ote: Prior to mounting the SPD, verify that the device has the same voltage
rating as the power distribution system in which it is installed by comparing
the nameplate voltage or model number on the SPD with the nameplate of
the electrical distribution equipment.
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.
enhance the performance of the device. See page 8 for the recommended
wire size and installation torque. For wiring diagrams, see figures 3 thru 6.
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.
NOTE: On a high-leg delta installation, the high-leg of the power
system must be connected to phase B of the SPD.
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.
