Unit Wiring
Field Power Wiring
DANGER
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.
DANGER
Dangers indicate a hazardous electrical situation which will result in death
or serious injury if not avoided.
DANGER
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 eld 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 eld wiring.
NOTE: The installation of all eld wiring, must comply with all
applicable local codes and ordinances. The warranty
is void if the eld wiring is not in accordance with
these standards.
Depending on the unit conguration, the unit will come with
either a Fused Disconnect (factory-installed or eld supplied),
a Non-Fused Disconnect, a power block, or a combination in
cases where multiple sources of power are specied. Consult
the Unit Specic Electrical Schematics to determine the
number of required sources of power. Refer to Table 7 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 Specic Electrical
Schematics to determine if the electric heater will require its
own set of service conductors. Refer to “Daikin Applied Electric
Heater Modules” on page 113 for service conductor entrance
details pertaining to the electric heater.
The recommended entrance for eld 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 133 on page 65 and also noted in
Figure 132.
When planning the installation of the service conductors,
consider the information in Table 8, Table 9, and Table 10
on page 64. These tables provide details for the eld
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. Table 8 provides this
information for non-fused disconnects, Table 9 covers the
fused disconnects, and Table 10 details power block ports.
