• “OFF” - Indicates that the disconnect switch is
open, interrupting the main power supply to the
unit controls.
• “RESET/LOCK” - Turning the handle to this position
resets or disconnects the device. To disconnect, the
handle must be turned to the Reset/Lock position.
Pulling the spring-loaded thumb key out, so the lock
shackle can be placed between the handle and the
thumb key, locks the handle so the unit cannot be
energized.

The handle can be locked in the “OFF” position by
completing the following steps (see Figure 56, p. 73):
1. While holding the handle in the “OFF” position,
push the spring loaded thumb key, attached to the
handle, into the base slot.
2. Place the lock shackle between the handle and the
thumb key. This will prevent it from springing out of
position.

NNoottee:: All field installed wiring must conform to NEC
guidelines as well as State and Local codes.
An overall layout of the field required power wiring is
illustrated in Figure 57, p. 74. To ensure that the unit
supply power wiring is properly sized and installed,
follow these guidelines:

• Verify that the power supply available is compatible
with the unit nameplate rating for all components.
The available power supply must be within 10% of
the rated voltage stamped on the nameplate.
• Use only copper conductors to connect the 3-phase
power supply to the unit.
Electric Heat Units
Electric Heat Units require one power entry as
illustrated in .
Use the information provided in Service Sizing data
and the “Power Wire Sizing & Protection Device
Equations,” to determine the appropriate wire size and
Maximum Over current Protection for the heaters/unit.
NNoottee:: Each power supply must be protected from short
circuit and ground fault conditions. To comply
with NEC, protection devices must be sized
according to the “Maximum Over current
Protection” (MOP) or “Recommended Dual
Element” (RDE) fuse size data on the unit
nameplate.
Provide grounding for the supply power circuit in the
electric heat control box.
Main Unit Power Wiring
Figure 58, p. 75 and Table 30, p. 75 lists the field
connection wire ranges for both the main power
terminal block and the optional main power disconnect
switch. The electrical tables beginning withTable 31, p.
76 list the component electrical data.
The electrical service must be protected from over
current and short circuit conditions in accordance with
NEC requirements. Protection devices must be sized
