Power Connection
230/208-Volt Line Cord Connected Units
Line cord kits consist of a self-aligning nine-
pin molded connector, that plugs into a mating
connector on the Zoneline chassis, and an insulated
line cord with an electrical plug on the end. The
confi guration of the electrical plug conforms to NEC
standards for the circuit amperage, and the position
of the wires in the nine-pin connector determines
the heater wattage and current requirements when
it is plugged into the Zoneline chassis.
The power connection kit is selected by the
amperage of the circuit, where it will be installed.
Each line cord kit has an integral Leakage Current
Detection and Interruption (LCDI) or Arc Fault
Current Interrupter (AFCI) device as required by the
National Electrical Code (NEC) and Underwriters
Laboratory (UL) for line cord connected air
conditioners manufactured on or after August 1,
2004. The line cord power connection kits are shown
in the table below.

230/208-Volt ― Permanently Connected Units
Permanently connected units do not require
the LCDI or AFCI device. Permanent connection
is usually made through the use of a sub-base.
Each 230/208-volt sub-base consists of a sub-
base with an appropriate receptacle for minimum
circuit amperage, a chaseway to route the power
connector from the sub-base to the chassis,
wiring to connect the sub-base to building wiring,
and a short line cord with a self-aligning nine-pin
connector to connect to the chassis and plug into
the receptacle in the sub-base.

Permanent, or direct-wired, installation of a
230/208-volt unit requires a junction box kit,
RAK4002A, that attaches to the chassis to form
an enclosed junction box. The short sub-base line
cord may not be used without the sub-base. For
6100 Series 230/208-volt units, where a permanent
installation using fl exible conduit is desired, the
RAK4002A forms an enclosed junction box on the
chassis.
The RAK4002A has a 7/8-in. diameter hole to allow
conduit to be connected to the junction box. A
line cord kit (See
Receptacles/Sub-Bases
purchased and modifi ed to allow direct connection
to the building wiring.
The line cord kit should be cut about 8 inches away
from the 9-pin connector. Strip the insulation off
the end of each conductor to expose wires for fi eld
connection. These wires are then connected to the
building wiring by fi eld-supplied connectors.
