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 junction box and wiring to connect the receptacle to the building wiring.
265 volt sub base DOES NOT include short power cord
* 30-amp heater wattage is reduced in low fan operation.
Specifications subject to change.
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
and it is enclosed.
Since 265-volt units may not be line-cord connected, an LCDI device is not required.
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 four-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, RAK4002D, 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 and junction box.
For AZ45 and AZ65 Series 230/208-volt units where a
permanent installation using flexible conduit is desired,
the RAK4002D forms an
enclosed junction box on
the chassis. The RAK4002D
has a hole to allow a 1/2"
trade size electrical conduit
and a square knockout
for the chaseway 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 four-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.
