Instruction manual

Follow steps 1–5 to make wiring connections.
1. Turn off all power supplying this equipment through the Panel Circuit
Breaker or Primary Disconnect before working on or inside the
equipment. (For additional protection, an integral switch may be used)
2. Mount the SPD as close as possible to the panelboard being protected.
3. Connect the SPD to the panelboard using an approved wiring method.
The connecting wires should be twisted (1/2 turn for each foot of length)
to enhance the performance of the device. See page 8 for the
recommended wire size and installation torque. For wiring diagrams,
see figures 3 and 4.
a. Connect the ground wire to the GROUND bus of the distribution panel.
Where applicable, connect ground to the SPD module.
b. Where applicable, connect the neutral wire to the SPD module.
c. Be sure the circuit breaker is open (OFF) prior to making any
connections of any kind. If a circuit breaker or circuit breaker space is
not available, connect to the electrical panel bus and then to an
integral disconnect utilizing the 3M or 10ft tap rule. (See NEC
240.21(B)(1)(4)). Be sure the disconnect is open (OFF) and the circuit
is de-energized before making any connections. Connect a wire (in
conduit) to each phase (HOT) terminal on the LOAD side of a circuit
breaker. Refer to the markings on the device when connecting the
phase, neutral, and ground conductors. Fuses are not
recommended for protection unless the fuses are specifically
designed for use in an SPD application.
4. After all connections have been made, reinstall any barriers that have
been removed, close the door or replace the cover.
5. Restore power to the equipment as required. If the SPD is properly installed
and functioning, the green LED indicators on the display will be lit.
If you have any questions pertaining to the installation, contact your APC
representative.
NOTE: Always install the SPD on the LOAD side of the main disconnect.
