POWER CONNECTION FOR 4100
AND 6100 SERIES ZONELINE UNITS
All 4100 and 6100 Series Zoneline units are equipped with
universal heaters allowing chassis installation flexibility. The
Zoneline units are connected to the building power supply
by a unique power connection kit. By utilizing a separate
universal power connection (UPC) kit, each unit is capable of
providing various outputs of electric resistance heat to more
closely meet the heating requirements of the particular room,
thereby increasing the installation flexibility of the particular
chassis. This power connection kit is the only means of
supplying power to the Zoneline chassis. The appropriate
kit is determined by the voltage, the means of electrical
connection, either line-cord connected or permanently
connected, and the desired resistance heat output that may
be supported by the branch circuit.
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 insulated line cord with an electrical plug on
the end. The configuration of the electrical plug conforms
to National Electrical Code (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 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 appropriate receptacle for minimum circuit
amperage, a chaseway to route 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 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, which attaches to the chassis to form an
enclosed junction box.
The short sub-base line cord may not be used without
the sub-base.
Electric Heat Amps include electric heater and fan motor current draw.
Each 265-volt sub-base kit consists of a sub-base with appropriate receptacle for minimum circuit
amperage, a chaseway to route the power connector from the sub-base to the chassis and wiring
to connect the sub-base to the building wiring.
*Wattage not available with 7,000 BTU systems.
The 265-volt power connection kit must be ordered separately.
All wiring must conform to local electrical regulations
and codes.

265- or 277-Volt Unit Installation — Permanently
Connected Units
NEC (Article 440.60) requires permanent connection for units
connected to power sources over 250 volts; therefore these
units must be permanently connected (direct-wired) with
field-supplied connectors. Units connected using a sub-base
meet the requirement for permanent connection since all
wiring is internal wiring between the
sub-base and the chassis.
Since 265-volt units may not be line-cord connected, an LCDI
device is not required.
For 4100 and 6100 Series 230/208-volt units where a
permanent installation using flexible conduit is desired, the
RAK4002A forms an enclosed junction box on the chassis.
The RAK4002A has a 7/8"-diameter hole to allow conduit to
be connected to the junction box. For direct connection,
purchase and install the appropriate Universal Power Supply
Kit (also referred to as
the Direct Connection Kit
below) that matches the
ampacity of the building
circuit connected to the
unit. This nine-pin
connector with three
7"-long conductor wires
is used for direct
connections to the
building wiring inside
a direct-connect junction
box. These wires are then
connected to the building
wiring by field-supplied
connectors.
Specifications subject to change.
