READING STATUS OF PA AND PB SERIES DEVICES
Visual Status
Protection is indicated by one (1) LED for each phase. An excessive surge, a lightning strike, or a loss of power can cause
one or more LEDs to turn off. If power is provided to the SPD unit and one or more LEDs are not illuminated, the unit has
been compromised and should be replaced.
REMOTE MONITORING
For units with remote monitoring contacts option (“-A” suffix), the SPD is equipped with Form C (SPDT) NO/NC dry contacts.
The maximum load is 4 amps (resistive) at 120 VAC.
To connect the remote monitoring unit (sold separately), wires properly sized to the load shall be connected to the remote
contacts connector (green) located on the SPD board. A minimum of 18 AWG, 600V rated conductors should be used to
provide the connection.
IMPORTANT NOTE! During a power failure, the SPD continues to provide full protection, despite the lack of visual
status indication. However, if the unit lacks power as a result of the circuit breaker being in
the off position, the SPD is off-line and will not provide protection.
