Installation
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before
servicing. Follow proper lockout/tagout procedures to ensure the power
can not be inadvertently energized. Failure to disconnect power before
servicing could result in death or serious injury.
Once the door has been opened, it can be closed with the handle in any one
of the three positions outlined above, provided it matches the circuit breaker
position.
An overall layout of the field required power wiring is illustrated in Figure 19.
These diagrams are representative of standard applications and are for
general reference only. Always refer to the wiring diagram that shipped with
the unit for specific electrical schematic and connection information.
Main Unit Power Wiring
Table 3 lists the field connection wire ranges for both the cam-type
connector and lug-type connector in the main power supply box The unit
electrical data is listed in Table 4. The electrical service must be protected
from over current and short circuit conditions in accordance with NEC
requirements. Protection devices must be sized according to the electrical
data on the nameplate. Refer to the “Power Wire Sizing & Protection Device
Equations”, for determining;
A. the appropriate electrical service wire size based on “Minimum Circuit Am-
pacity” (MCA),
B. the “Maximum Over current Protection” (MOP) device.
C. the “Recommended Dual Element fuse size” (RDE).
1. A field supplied disconnect switch must be installed at or near the unit in
accordance with the National Electrical Code (NEC latest edition). Refer
to the “Power Wire Sizing & Protection Device Equations” (DSS calcula-
tion), for determining the correct size.
2. Complete the unit's power wiring connections onto either the factory sup-
plied cam-type receptacle, or the factory mounted lug-type connector
inside the power supply box. There are also 3/8” holes provided for field
supplied wire terminals. Refer to the customer connection diagram that
shipped with the unit for specific termination points.
3. Provide proper grounding for the unit in accordance with local and
national codes
