Diagnostic Operation
•LED ON = Normal operation.
•LED OFF = Fault. Check line voltage, breakers and connections. If OK,
replace unit. (see Figure 3)
•Remote Monitoring (Dry Contact option) (see Figure 4). A three-pin
socket and plug are provided to allow the customer to wire one set of
normally open (NO) and normally closed (NC) “Dry”Contacts to a
remote monitoring indicator. The customer must provide power for this
indicator, keeping within the specifications shown in Figure 4.
The SPD’s internal electrical relay energizes only in the event of a
fault within the SPD.
NOTE: The supplied three-pin plug can accept up to #16 AWG
(1.5mm2) wire.

1. Turn off all power supplying this equipment before working on or
inside equipment.
2. Mount the SPD as shown in Figure 1.
3. Confirm SPD is rated for your system by comparing the L-N voltage
measurements to the Rated Line Voltage on the product label (120V
or 230V). (see Figure 2)
4. Insure that the in-line circuit breaker rating and wire size are per National
and Local Codes and match the current rating on the SPD label.
5. Connect as shown in Figure 2.
