Field Power Wiring

LOCKOUT/TAGOUT all power sources prior to wiring or servicing the unit.
Hazardous voltage can cause serious injury or death. Disconnect electric
power before servicing equipment. More than one disconnect may be
required to de-energize the unit.
Dangers indicate a hazardous electrical situation which will result in death
or serious injury if not avoided.
Proper line voltage and phase balance must be provided. Improper voltage
or excessive phase imbalance may result in severe damage to the electrical
components within the unit.
For the unit to operate, power must be supplied to the
unit through field installed service conductors. Electrical
characteristics, such as Unit Voltage, Minimum Current
Ampacity (MCA), and Maximum Overcurrent Protection (MOP)
are found on the Unit Nameplate. These characteristics must
be considered when planning the installation of the service
conductors and other applicable field wiring.
NOTE: The installation of all field wiring, must comply with all
applicable local codes and ordinances. The warranty
is void if the field wiring is not in accordance with
these standards.
Depending on the unit configuration, the unit will come with
either a Fused Disconnect, a Non-Fused Disconnect, a power
block, or a combination in cases where multiple sources
of power are specified. Consult the Unit Specific Electrical
Schematics to determine the number of required sources of
power. Refer to Table 5 for the standard multiple point power
connection options and their function.

The point of connection for service conductors will be within
the Main Control Panel. However, on some units service
conductors may be required to be installed in the Electric
Heater Control Panel. Consult the Unit Specific Electrical
Schematics to determine if the electric heater will require its
own set of service conductors. Refer to
Modules" on page 74
pertaining to the electric heater.
The recommended entrance for field installed service
conductors that terminate in the Main Control Panel is through
the Panel Entrance Plate in the bottom right corner of the
control panel enclosure. This entrance to the Main Control
Panel is shown in Figure 35 on page 32

When planning the installation of the service conductors,
consider the information in
page 32. These tables provide details for the field wired
service conductor connections including the number of
ports that will be available per phase as well as the range of
conductor gauge that they will accept.
