For CurrentGuard Compact Units (model number ends with -M)
Verify that all “Phase Protection Status” indicating lights are illuminated . The
“Service Required” indicating light illuminates only upon failure of one or more
phases (indicating an alarm condition) . Audible alarm should not operate under
normal conditions . The audible alarm can be “muted” by pressing the “ALARM
SILENCE” button, which subsequently will illuminate the “ALARM SILENCED”
light . Pressing the “ALARM SILENCE” button again will enable the alarm .
CAUTION:
Prior to installation ensure the system configuration and voltage is
equivalent to the CurrentGuard unit being installed .
The CurrentGuard units come with 36" of #10AWG conductors . Each phase
conductor is labeled (Phase A, B or C) . Ensure that the conductor lengths are
kept as short and straight as possible . On all high-leg delta systems, the high-
leg (208V L-N) must be connected to the Phase B of the SPD (color-coded
orange according to NEC) .
* The 3-wire plus ground Delta CurrentGuard does not have a neutral
conductor.
