Wiring and Connections (cont’d)
SENSING CIRCUITS
Sensing input range is 175 - 600Vac. DIP switch SW2-1
must be set appropriately.
Single Phase Sensing
Connect PM500 terminal E1 to output lead L1 and E2
to output lead L2. PM500 terminal E3 is jumpered to
E2. Refer to Figure 3b for typical connections.
3 Phase Sensing
Connect PM500 terminal E1 to output lead L1, E2 to
output lead L2 and E3 to output lead L3.
If used in a paralleling application, a paralleling CT
will be required in the generator B phase. Paralleling
CT must be sized to provide either a 1A or 5A signal
when the generator is under full load. DIP switch
SW2-6 must be set appropriately. Refer to Figure 3a
for typical connections.
