2.2 Receiving & Unpacking
Unpack equipment and check for damage and shortage of parts. If damage or shortage is noted, file a claim with the carrier immediately and notify the factory.
Do not remove any identification tags attached to the components, as they will be useful for identification during the installation.
The packaging is meant for maintaining the assemblies as clean and dry while in transit and for short periods of storage. Upon receipt of the equipment, the material received should be checked against the packing lists to be sure that all parts are received. An examination should be made to determine if any damage was sustained during shipment. If damage or shortage is noted, file a claim with the carrier immediately and notify the factory.

2.3 Storage
All components of the device are suitable for outdoor use. The storage requirements are listed below:
· Inspect all packing material thoroughly prior to storage.
· Store Indoors.
· Protect cabinets that encase electronic components. Treat with care as you would a SCADA network terminal unit (NTU) or digital relay.
· Protect unit from being immersed in water and away from high humidity.
· The 3 components should be stored in their original packing boxes until preparation for installation.

3 Installation & Configuration Procedures
3.1 Assembly
The device is shipped from the Southern States factory fully adjusted and ready for installation and configuration to the customers relay.
Pr elim i n ary

The Quality Name in High Voltage Switching

Page 12

The device is shipped with the intent to minimize and simplify installation. Once installed the assembled unit is ready to be configured. Configuration of device will be described in a later section.
The device is typically shipped in three major sections:
1. Sensors:
o Correctly orient each sensor to the 3 phases, one for each phase. (If installed on a CapSwitcher® or Circuit Switcher, connect the sensor directly to the interrupter bus. If on a switch, connect to the phase or interrupter bus.
o Orient each sensor eye toward the Receiver Cabinet position.
o Tighten all bolts to proper torque using customer’s lock tight procedures.
2. Receiver Antenna Enclosure:
o Three whip antennas per enclosure.
o Mounting brackets – Mount cabinet on structure in line of sight of sensors.
o Conduit – Install conduit between Receiver (control) Cabinet.
3. Control Cabinet:
o Install cabinet to structure with mounting brackets at working height and connect conduit from Receiver Antenna enclosure.
o Host Computer Module
o Southern States supplies a Schweitzer SEL 751A Relay (or customer supplied relay)

3.2.1 Mounting 3.2.1.1 Sensors

Page 14

Mount the three sensors according to their preset designations as marked on each sensor (L, M, R). The orientation shown in Figure (1) on the preceding page is shown from the side of the switch where the sensors and receiver will be mounted.
A. Brackets – Begin by identifying left, middle, and right sensors (sensors will be labeled accordingly). Left, middle, and right sensors should be mounted on the same side as the receiver cabinet. i) Mount the sensors in their predetermined position (shown in Figure 2 and 3) utilizing the included sensor mounting bracket to adjust the angle of the sensor (one bracket per phase).
B. Adjust each sensor bracket (Figure 3 Item 3) so that the “eye” of each sensor is aimed directly at top of the receiver cabinet.

3.4 Voltage Test
The following instructions shall be performed after VAC + VDC power sources have been restored.
Equipment- You will use the following equipment to test system:
– DC power – AC Power – Multimeter

Testing DC + AC Power 1. Ensure that you have connected the VAC and VDC wires of the conduits to the
correct terminal blocks and locations in the ICS large cabinet (refer to SS wiring diagram). Open all circuit breakers/ fuses in the Control Cabinet.
An open circuit breaker will be in the down position as shown below.
Perform visual inspection of all wiring within Control Cabinet and Receiver
Cabinet. Verify that all wires are properly landed and ensure power supply wires (AC and DC) are wired in their correct positions. 2. Disconnect power inputs from all modules. 3. Using a multi-meter, ensure you have the correct VAC + VDC feeding the ICS cabinet at the inputs located at the breaker switch.
If this is a unit that is set up for remote monitoring, please contact Southern States and ask to be connected to the Automation & Sensors Division at 770-9464562 to confirm that the unit is online and we are able to monitor the unit.
