WARNING All heaters must be fused in
accordance with National Electric Code
(NEC) for the full load amperage listed
on the nameplate rating for each
heater.
WARNING Failure to properly ground the unit(s)
per the National Electric Code could

Based on the NEC Table 310.15 for 75°C insulated copper wire @ 30°C
Ambient. Aluminum wire requires larger gauges.
Not all available (optional) voltages are listed in the
table.
For standard enclosures, remove the four screws
and take the bottom cover off. For NEMA 4/4X
enclosures, open the enclosure door.
NOTICE! Any option that requires field wiring must be
done with 600V cable per the schematic that
was shipped with the heater.
NOTICE! Use a 4-core cable or multi-stranded machine
tool wire from an approved isolating 3-pole
switch or circuit breaker.
NOTICE! Make sure the electrical cable is the correct
size to carry 100% of the full load current. See
table for proper wire sizes.
Standard: A pre-cut hole is already sized for
conduit connection. Skip to step C.
NEMA 4/4X: Using a hole punch, cut a hole the
proper size for the conduit connection; large
enough for the wire size for each heater. The
connectors need to be rated NEMA 4/4X to
ensure proper sealing of the enclosure.
Run wires through the appropriate size conduit.
Connect wires to the system terminal block or
fused disconnect inside the enclosure.
Connect the ground wire to the stud provided
with the “Ground” label beneath it.
I
f unit is ordered with a D1 or DC controller,
option, the DB9 connector for hookup on a
standard unit is located on the upper left/hinge
side of the cabinet. Please review the appropriate
Special Instruction & Operation Instructions
section for information regarding controller
programming and wiring. Proceed to the Start Up
Checklist once the steps in the Special Installation
& Operation Instructions section have been
completed or if you do not have this option.
