Field Wiring

General
Wiring must comply with all applicable codes and ordinances .
Daikin Applied's product warranty does not cover equipment
failures caused or contributed to by wiring not in accordance
with specifications. A tripped manual motor protector (MMP)
or open fuse indicates a short, ground or overload . Before
replacing a fuse or restarting a compressor or fan motor, locate
the trouble and correct . Use copper wire for all power lead
terminations . Contact the factory for information concerning
aluminum wire power lead terminations .
A single power terminal block is provided as standard, and
wiring within the unit is done in accordance with the
Electric Code (NEC) . Each branch circuit within the control
panel is individually protected by fuse or MMP. A single field-
supplied disconnect is required or a unit-mounted, non-fused
disconnect can be ordered with the unit .
A knockout is located on the right or left front unit upright for
locating unit power entry. 24 V field connections are suitable for
Class II wiring .
Unit Disconnect
Disconnecting means are addressed by Article 440 of the NEC,
which requires "disconnecting means capable of disconnecting
air conditioning and refrigerant equipment including motor-
compressors, and controllers, from the circuit feeder ." Select
and locate the disconnect switch within the NEC guidelines .
Location requirements per NEC are that the disconnect is
located in a readily accessible position within sight (50 feet) of
the unit . A factory-mounted, non-fused disconnect is available .

Return Air and Outside Air Sensors
All units are provided with a return air sensor . It is connected
to the patch panel and is coiled and placed in the control box
of the unit for shipment . Field-installation is required to put it in
the return air stream for proper unit operation . The return air
sensor is connected to the unit's patch panel at location PL1
(see IM 919) .
The outside air sensor is optional and can be ordered with the
unit. The outside air sensor is field wired to terminal strip TB2.
It is connected at terminals 122, 123, and 123G .
The mixed air temperature sensor is already installed at the air
inlet .
Mount the sensors in areas that are exposed to representative
temperature conditions . Mount them at a position that has good
air mixing and does not have stratification. Sensors can be
mounted in the ductwork using a grommet (see
