SME BATTERY CABINET
INSTALLATION MANUAL

Safety instructions

It is critical that the below safety instructions are carefully read and understood. High voltage DC may be present within the battery cabinet even when turned off .
Only trained and qualifi ed electricians should install or maintain the battery cabinet The battery cabinet is heavy and will require lif ting equipment in all circumstances The battery cabinet must only be moved when it is empty, under no circumstances can it be moved once the batteries are installed
Before removing any covers or batteries the battery cabinet should be isolated from the PCS and DC Cabinet if fi tted
The installation order of the battery packs and high voltage box is critical, incorrect installation could result in serious damage
Signs and symbols in this guide
Pay particular attention to this instruction, as it represents risk of damage to the product or injury
Required tools and equipment

• Gloves
• Socket/spanner set
• Screwdrivers
• Suitably rated lifting equipment*

*The battery packs weigh 76kg. It is advised that these are not lif ted manually and the use of a lif ting device is recommended. Please speak to a GivEnergy representative if uncertain.

HANDLING

Delivery and unpackaging
The battery cabinet and battery packs are delivered on 2 separate pallets.
The battery cabinet will be delivered palletised in a cardboard box:

1. Remove all packaging and foam protection1.
2. Remove the lower black trim on all sides of the battery cabinet – be careful not to lose any of the bolts.
3. Unbolt the battery cabinet from its pallet on all 4 corners.
4. Lif t the battery cabinet to allow removal of the pallet, being careful not to put any body par t in a potential trap area/drop zone
5. The battery cabinet can now be positioned using lif ting equipment or a standard pallet truck.
6. The key to the door is attached to the handle6.

The battery packs and high voltage box are delivered on one pallet:

• Remove all outer packaging1.
• Carefully lower the battery boxes one at a time, using a lif ting aid if required2.
• Unbox batteries one at a time, taking care not to drop them3.
• Remove all foam and plastic protection4.

The battery packs have an electrical connector block on their rear, do not stand the batteries up as this could damage the connector.
Key dimensions

Environment criteria
To ensure optimal operation and lifetime of the system, it must be installed in an environment that meets the following criteria at a minimum:

• 0°C to 40°C
• 0 to 95% non-condensing humidity
• <5000m altitude
• In an area with adequate ventilation

The battery cabinet must only be installed internally on level fl at ground, it is possible to fix it to the fl oor on each corner if required.
Ventilation
The battery cabinet must have a suitable airfl ow to ensure optimal operation. All the battery packs are natural convection and do not have fan assistance. For more details please see the Ventilation guide.
Access
It is recommended that access to the area the system is located within is restricted. A locked door prevents immediate danger to the general public, however the emergency stop button is accessible on the front door.

ELECTRICAL AND DATA CONNECTIONS

Assembly
All battery packs and the high voltage box must be secured with 2 bolts on each side before powering up the battery cabinet.
All power and data cables should be fed through the cable entry cover at the bottom of the battery rack and then out of the grommets on the under tray. The cable entry cover is removable if additional access is required.
Note: Ensure that all grommets are located correctly to avoid sharp metal edges damaging the cables.
Multiple battery cabinets
When installing multiple 64kWh battery racks, a DC cabinet will be supplied. This cabinet off ers an additional level of control and protection as well as a position to connect the battery racks together. When a DC cabinet is provided the battery racks will take AC input from here. The DC cabinet is then powered from the PCS EPS output terminals (see DC Cabinet Installation Manual for more details).
High voltage box
It is critical that the high voltage box is installed into the bottom slot of the battery cabinet first and all input and output connections are installed before inserting any battery packs.
Battery packs
Battery packs must only be installed after the high voltage box is installed and connected.
Ensuring that both the MCCB and power button on the high voltage box are both OFF, the batteries can be installed in the order shown on the next page.The high voltage box front cover has sockets for DC output and AC input.
The AC input is used to power the UPS at the top of the battery cabinet, this ultimately provides power to all control circuits.
All connections in and out of the battery cabinet/high voltage box must be made prior to installing the battery packs.
DC output
Ensure the PCS DC switch is in the off position and use the supplied cables. Then, connect the ring terminal end to the PCS DC input terminals. Or, if fitting multiple battery racks, connect them all into the DC cabinet’s DC input terminals first, ensuring correct polarity.
AC input
Using the wiring harness provided, connect into the battery cabinet output terminals in the bottom right hand side of the PCS. If a DC cabinet is installed this supply will connect into the DC cabinet. See PCS or DC cabinet installation manual for details.
Data connections
For single battery installations – The high voltage box has 2 data connection points, one is to communicate with the PCS1, the other is for meter communication . Use the cables supplied, these can be extended as required.
See PCS installation manual for more details
See Meter installation manual for more details
For multiple battery installations – Only the PCS data connection is used to connect the terminals in the bottom of the DC Cabinet.
See DC cabinet installation manual for details
The EMS is located in the top of the battery cabinet and provides control to the whole system. When multiple battery cabinets are installed only one EMS is utilised and this will be located within the DC cabinet.
The EMS communicates with all battery packs, high voltage boxes, PCS, metering and the internet via either LAN or WiFi.
The GivEnergy engineer will help install and confi gure the LAN or WiFi connectivity and ensure communication with the online portal.

POWER PROCEDURES

Power-on procedure
Once all connections are terminated correctly with satisfactory test results, the following turn on procedure should be followed:

1. Release the emergency stop button if pressed.
2. Turn on the PCS (and DC cabinet, if fi tted) following its power-on procedure.
3. Turn on the MCB located at the top of the battery cabinet.
4. Press the on/off button on the front of the UPS.
5. Once lit up, press and hold the on/off button on the UPS for 3 seconds, checking that output voltage is shown on the output on the UPS screen
6. Press the power-on button on the high voltage box6.
7. Turn ON the MCCB on the high voltage box7.

Emergency shutdown procedure
In an emergency press the EPO button on the PCS fi rst then all battery cabinets/racks.
Standard shutdown procedure

1. Turn the PCS off fi rst, following its shutdown procedure.
2. Turn OFF the MCCB on the high voltage box.
3. Press the power button on the high voltage box.
4. Press and hold the on/off button on the UPS for 3 seconds, checking that the voltage is gone from the output on the UPS screen
5. Turn OFF the MCB located at the top of the battery cabinet.
6. Repeat for additional battery cabinets.

INITIAL TESTING / COMMISSIONING
All GivEnergy commercial storage solutions include an on-site commissioning service. Our engineer will ensure correct communication with meter, battery packs, EMS and PCS. To aid in this testing, the engineer will initially run a low power test in ‘manual ’ mode — setting the system to complete a 5 minute charge followed by a 5 minute discharge and a rate of 10kW.
Once this is complete, where electrical supply parameters allow, a full power charge and discharge will be ran for a period of 15 minutes in each direction. Depending on electrical limitations on site, this test can be adjusted to power levels with site tolerance Any additional tests can now be completed including system specifi c operation such as back up power. Once the above testing is successfully completed, the system will be set to run in its agreed operational modes and a demonstration can be given to the client and/or installer.
Our engineer will supply commissioning paperwork once complete, the date of which will commence the PCS warranty.

MAINTENANCE AND SUPPORT

Maintenance
Ensure that the ventilation holes on the front door of the battery cabinet do not become blocked with dust.
Support
Free remote suppor t is included with all systems for the period of the warranty.
