Input Cable Installation - Phase Stabilizer 15 - 100 kVA and Constant Power 18
The customer-furnished input power cable provides power from the building power source to the unit. Both the
circuit which feeds this cable and this cable should be dedicated to providing power only to this unit. This cable
must include three power conductors and an insulated ground conductor. Size the cable to suit the unit kVA
rating, the input voltage and the overall length of the cable. The input power cable size and installation must be
in accordance with the National Electrical Code (NEC) and applicable local requirements.
A parity sized ground, with respect to the primary input conductors is recommended. The grounding conductor
is to be grounded to earth at the service equipment or other acceptable true building ground.
The input power cable should be installed through the left side panel. No holes are provided in the panel. A
hole can be sized, located and drilled or punched when the cable is installed.
If cables are crossed or wires are likely to touch, insulating sleeves or their equivalent must be used to prevent
wires from touching.
PROCEDURE:

5.
Remove rear panel by unbolting 6 screws located on the corners and right and left sides of the panel.
DANGER!!
VERIFY THAT INCOMING HIGH-VOLTAGE CIRCUITS ARE DE-ENERGIZED
BEFORE CONTINUING WITH THIS PROCEDURE.
6.
Punch or drill holes in left side panel to accomodate input cable.
7.
Route and connect the 3 power wires to input power terminals labelled L1, L2, and L3.
See Illustration 1-6.
