The maximum number of connected panels cannot exceed 32.
The GR-750x series provides an ideal solution for medium to large scale facilities such as department stores, hotels, factories.
1.2 Safety
WARNING 
To ensure safety and proper use of the device read all accompanying documents carefully and follow the provided instructions.
It is recommended that this product is installed, commissioned, and maintained by trained technician personnel in accordance with:

• The regional regulations for installation and maintenance of electrical appliances in buildings.
• Manufacturer’s instructions.

The device main power supply is rated at 220-240Vac/50-60Hz and is a Class I product (the corresponding terminal contact with the “Protective Earth” marking ( ), inside the device, must be connected to the building’s ground to ensure proper function and safety). The mains power supply of the device must be connected to the building’s electrical installation, with its own separate power line and circuit-breaker rated at 16A, labeled “Emergency lighting system – Do not switch off”.
1.3 Terms and definitions
1.3.1 Point
The term “point” refers to any addressable device connected to the panel. For example, an emergency luminaire.
1.3.2 Emergency mode/In emergency
When the system or a point is referred as being in emergency or emergency mode, it means that its mains power supply is unavailable, and it is operating by drawing power from its battery.
1.3.3 Inhibit mode
A luminaire set in inhibit mode, will not function as an emergency light. If its mains power supply is unavailable, it will switch off its lamp (if it is a continuous operation luminaire) or it will not switch on (if it is a non- continuous operation luminaire). Enabling and disabling the inhibit mode can only be done by the user (manually).
1.3.4 Forced emergency
Forces the luminaires to switch to emergency mode, even though the mains power supply is available.
1.3.5 Loop circuits
All models of the GR-750X series use the same loop boards, they only differ in number. The loop output connection terminals come pre-installed with a short- circuit adapter (it links +L to +LF and –L to –LF terminals, to form a closed loop circuit).
A loop circuit can operate with up to 250 addresses and a maximum of 250 points connected to it.
1.3.6 Function test
Function test procedure initiates a self-test (operational test) procedure of the luminaires connected to the panel, to verify their proper operation. No specific equipment is required and can be manually performed at any time or scheduled at specific days of the week at a certain time. During the test, a LED indicator flashes on the luminaire indicating the ongoing operation. For more information about the LED indicators of the luminaire, refer to its manual.
Upon completion of the test, if a problem is detected by the luminaires, the panel will be notified, the corresponding fault will appear in the fault list with detailed information.
1.3.7 Duration test
Duration test procedure initiates a self-test (autonomy test) procedure of the luminaires connected to the panel, to evaluate the endurance of their batteries. No specific equipment is required and can be manually performed at any time or be scheduled up to two times per year. During the test, a LED indicator flashes on the luminaire indicating the ongoing operation. For more information about the LED indicators of the luminaire, refer to its manual.
Upon completion of the test, if a problem is detected by the luminaire, the panel will be notified, the corresponding fault will appear in the fault list with detailed information.

INSTALLATION

2.1 Mounting the panel

WARNING
All installation operations must be done while the panel is disconnected from mains power supply and batteries. Only trained personnel should carry out operations inside the panel and only after taking all the precautionary measures.
Prior to installing/maintaining the panel, read the manual and have knowledge of the system’s capabilities, functionality, and design to ensure proper operation.
Do not connect or disconnect system components while mains power supply or batteries are connected. Prior to any operation inside the enclosure of the panel, ESD prevention measures should be taken.
The panel mounting area must be clean, dry, and free of collisions and vibrations. The panel must be permanently installed on a fixed position in an indoor location. In (Figure 1) the interior mounting holes of the panel are marked. Use all three mounting holes with the included wall mounting accessories of the package for proper installation (plugs and screws).
The panel should be placed at least 1m above floor level, 1m bellow roof level and at a minimum distance of 30cm from other electronic devices. No other lines should cross the wall behind the panel except the panels own power supply. The panel should be placed in a visible and accessible area to the building’s stuff, fire and lighting safety personnel. 2.2 Power supply connection
The power supply cable must be a 3−core double insulated wire that meets the voltage and current requirements of the panel. The ground terminal (marked with on the power management board) must be connected to the installation’s ground (protective earth) to ensure proper and safe operation of the system.The interior of the control panel has space suitable for two 12V lead-acid batteries (Pb) with nominal capacity of 7Ah, 9Ah, 12Ah or 15Ah. Both batteries must be the same model, type and have the same nominal capacity.
The two batteries must be connected in series. Three cables are provided to connect them, two of them are pre-installed on the board’s battery terminals. The red wire must be connected to the positive terminal (+) of the first battery. The black wire must be connected to the negative terminal (-) of the second battery. A jumper cable is included in the accessories bag, to connect the two other terminals (negative terminal (-) of the first battery to the positive terminal (+) of the second battery), as it is shown in the figure below:

2.3 Point wiring
Use a cable that meets the specifications below to connect the loop board with the points:

1. The installation cable must be suitable for data transfer.
2. LiYCY (TP) type cables are recommended, with cross section from 0.75mm 2 to 1.5mm 2 or YSLYCY-JZ with cross section from 1mm 2 to 2.5mm 2 , depending on the number of connected points, the topology of the installation and the length of the cable.
3. The communication cables must be placed 40cm away from any MAINS cable.
4.  The communication cables must be placed 5m away from any motors or power station.
5. The cross section depends on the distance and the number of installed points. The communication cable must contain 2 conductors, a shield and no additional unused conductors
6. Select shielded cable for every installation.
7. The cable shield must be reconnected in every cut during the length of the loop and must be terminated to the «PE» (Power Earth).
8. The positive and negative polarity must be maintained throughout the installation.
9. All points must be connected in parallel with the output.
10. Low resistance, less than 25 Ohm/km – the total impedance of each core of the cable should not be more than 20 Ohm.
11.  Wire cross section should be between 0,7mm 2 and 2,5mm 2 .
12. Low capacitance, less than 200 pF/m – the total capacitance of a single cable should not exceed 400 nF.

Addressable Luminaire Connections

1. The GR-7500 can support up to 250 points per loop.
2. The maximum connected points to each cable must not exceed 75 for open loop and 150 for closed loop.
3. Each point must have unique non repeatable address.
4. No arithmetic address sequence is obligatory.12. Wire cross section should be between 0,7mm 2 and 2,5mm 2

WARNING
The maximum length of a single loop cable should not exceed 2000m. The maximum connected points per cable are 150.
The upper and lower cable openings of the metallic enclosure of the panel can be used to drive the cables through. The rubber plugs should not be removed from the openings, so the ingress protection IP30 remains unchanged. Instead, pierce a hole on the rubber plug, big enough to barely fit the cable and drive the cable through it. To connect one or more points to the loop output terminals, remove the short-circuit adapter.
IMPORTANT

1. The cable’s shield must be reconnected in every cut along the length of the loop and must be connected to the earth bar of the panel
2. The positive and negative polarity must be maintained along the length of the loop
3. All points must be connected in parallel with the output
4. If the number of installed points on a loop circuit exceeds 75, or if the length of its cable exceeds 300m, then a closed loop connection topology is always recommended, to minimize communication issues

The below figure describes the parallel connection of addressable points, which use a 2-way terminal, with theloop board:
Notes:

• Max 250 points per loop device
• Max 150 points per line

Table 1 – Recommended cable cross section

| Loop cable length
---|---
200m| 500m| 1.1000m| 1500m| 2000m
Point Number| 50| 0.75 mm2| 1 mm2| 1 mm2| 1.5 mm2| 2.5 mm2
100| 1 mm2| 1 mm2| 1.5 mm2| 1.5 mm2| 2.5 mm2
150| 1.5 mm2| 1.5 mm2| 2.5 mm2| 2.5 mm2| 2.5 mm2

The below figure describes the parallel connection of addressable points, which use a 4-way terminal, with the loop board:
Notes:

• Max 250 points per loop device
• Max 75 points per line
• Max 50m initial cable
• Max 300m cable per line

2.4 Configure point address
A valid (1-250) and unique address (per loop) must be set for each point, using the onboard address selection DIP switch on each point.
Certain models, such as ZLD-xx, GR-29X, do not have onboard DIP switches. In this case, the address must be set using the panel by connecting and setting the luminaires one-by-one from the CHANGE POINT ADDRESS menu.
For more information on the point’s address configuration, refer to the manual of the specific luminaire.
It is essential to draw a schematic of the installation. The schematic should include cable length, cable crosssection, and the location of each point. It could be useful for the maintenance of the installation and an efficient way to locate a faulty point or line problem. 2.5 Wiring verification

IMPORTANT
The following steps should be performed while the cables are NOT connected to the loop board terminals.
Steps to verify the integrity of the installation’s wiring:

1. Verify the mains power supply to the panel and the connection of the protective earth (PE) to the board terminals. The panel should be supplied by a separate line with its own circuit-breaker.

2. Using a multimeter measure the resistance between the protective earth (PE) terminal and the panel’s earth bar. It should be less than 10 Ω. Higher values indicate bad panel grounding, and it is highly dangerous and unsafe to operate it.

3. Optical inspection of each cable for possible wear/damage caused during the installation.

4. Optical inspection of each point connection for bad/wrong wiring.

5. If points are connected using a loop topology, using a multimeter measure the resistance between each L+ and its corresponding LF+ line. It should be less than 60 Ω. Higher values indicate faulty connections/cable and should be investigated and resolved.

6. If points are connected using a loop topology, repeat the previous step for loop cable, each L- and its corresponding LF- line and each shield line start-finish.

7. If points are not connected using a loop topology (no return line), connect temporally the L-, L+ and its shield, at the last point (end of line) together. Using a multimeter measure the resistance between the start of L- and L+ line.
   It should be less than 60 Ω. Higher values indicate bad connections/faulty cable and should be investigated.

8. If points are not connected using a loop topology, repeat the previous step for the L- or L+ line and its shield. IMPORTANT: Remove the temporal connection at the end of the line between L-, L+ and its shield.

9. Using a multimeter measure the resistance between each L+ and its corresponding L- line. It should be more than 10 kΩ. Lower values indicate faulty connections/cable/short circuits and should be investigated and resolved.

10. Using a multimeter measure the resistance between each L+ and its corresponding shield line. There should be no circuit continuity (at least 10 MΩ). Lower values indicate faulty connections/cable/short circuits and should be investigated and resolved.

11. Repeat the previous step between each L- and its corresponding shield line, each L+ and the protective earth (PE) line and each L- and the protective earth (PE) line.

12. Every time a problem is detected and corrected on a line, all the check for this line should be repeated from the start.
