Wiring of the CT's:
For each of the six 3-phase metering elements A through F, connect the current transformers as shown in the
diagram below.
Note: The CTs are insensitive to orientation and may be placed on the wires to be monitored with the CT faces
™
in either direction. The CTs are connected on the PowerScout
board in positions labeled L1, L2, L3 and must
be placed on the phase wires of the load to be monitored corresponding to the phase of the voltage leads. i.e.,
The CT labeled L1 must be placed on L1 phase voltage wire, the L2 CT must be on the L2 voltage, and the L3 CT
on the L3 voltage.
Wiring of the Voltage Input:
™
Last, connect 14 AWG THHN (or equivalent) wires to the PowerScout
CAT III voltage terminals as shown in the
diagram above after a building installed dedicated circuit disconnect breaker while being as close as possible to
™
it (following the local electrical codes). Mark the breaker as the disconnect for the PowerScout
. Note that
™
the PowerScout
has an internal non-user replaceable .5 Amp Internal fuse protection.
Warning: DO NOT EXCEED 600Vac PHASE TO PHASE CAT III. When complete, close the enclosure cover, if
equipped.
Attention: NE PAS DÉPASSER UNE PHASE À 600VAC CAT III. Une fois terminé, fermer le covercle, s'il y en a un.
