INSTALLATION
Step 4: Electrical ConnectionsA wiring diagram is located inside the control compar tment on the right side of the pul l-out control-panel
assembly. To access the control-panel compartment, remove the screw at the top of the control panel and
pull the control panel out.
Units ordered with a 115VAC, 60Hz, single-phase electrical rat ing are f actory-suppl ied with three-wire cord
and three-prong plug, which fits any standard three-prong gr ounded receptacle.
Units ordered with a 208/240VAC, 60Hz, single- or three-phase el ec tric al r a ti ng ar e f ac tor y-equipped with a
2-pole terminal block located behind a cover plate loc ated at the rear of the unit. To connect the supply
wires, remove the appropriate cover plate. Route the suppl y wires and t he gro unding wire thr ough the s train
relief fitting to the terminal block. Insert the suppl y wires, one each, into the two poles of the term inal block
and tighten the screws. Insert the ground wire into the grounding lug and tig hten the screw. Re-attach the
cover plate.
Three phase units are wired as above, using only two supply wires. The third wire is not used and must be
properly terminated.
All units are shipped wired as specified by factory order. Conversion between sing le-phase and three-phase
can be accomplished by referring to phase loading an d line amperes chart on wir ing diagram f or wire size
and ampere requirements.
! WARNING
A POSITIVE GROUND CONNECTION IS ESSENTIAL. DO NOT ALLOW ANY T AMPERING OR
ADJUSTMENT OF ANY CONTROL OR WIRING. THE UNIT IS FACTORY SET. ADJUSTING ANY
INTERNAL COMPONENT OTHER THAN THE MAIN FUSE BLOCK CAN VOID THE W ARRANTY.
