VI. FIELD CONNECTIONS

A. A separate line voltage supply with a suitable branch

circuit protection device should be run directly from the

main electrical panel to the unit. A disconnect switch for

each branch circuit is a required part of this installation.

See the voltage label on the unit for circuiting and total

electrical load. The wiring diagram is located in the

wiring compartment, located on the top of the unit.

See Figure 7.

B. All eld wiring must be copper with a minimum

insulation of 60°C within approved conduit. If any of the

wire supplied in the unit must be replaced, it must be

replaced with copper wire with a minimum insulation of

90°C.

C. Electric and hot water heated air curtains are factory

equipped with an unit mounted solid state temperature

sensor located internally to measure the incoming

(return) air stream.

D. Remove the wiring compartment cover.

E. Connect all supply and control circuit wires according to

the wiring diagram provided.

NOTE: For Electric and Hot Water heated air curtains

provided with an optional remote thermostat, mount

and wire the thermostat according to thermostat

instructions and wiring diagram.

For BACnet-IP Integration –

see XI - Appendix C, “BACnet-IP integration.”

For Serial Network Connection - proceed to

XI - Appendix A, “Serial/Network Connection.”

NOTE: The air curtain must have been ordered from the

factory with this option.

For Wall Mounted Touchscreen – proceed to

XI - Appendix B, “Wall Mounted Touchscreen.”

if optional remote Touchscreen control of the

Intelliswitch™ has been ordered from the factory.

For Electric and Hot Water air curtains - proceed to

Section VI - Field Connections, otherwise proceed to

Section VII - Operating Instructions

A. ELECTRICALLY HEATED MODELS

The heater circuit may be controlled by an optional

remote thermostat or through the built-in Intelliswitch™

thermostat located on top of the air curtain. Overheating

protection is provided by auto reset thermal cutouts built

into the heater coil assembly (see the wiring diagram

located in the wiring compartment). See Figure 7.

B. HOT WATER HEATED MODELS

An optional water coil solenoid valve (by others or

Berner) may be controlled through the Intelliswitch™ or

independently. The Intelliswitch™ is capable of providing

the same voltage used for the motor to power a solenoid

load up to 5 amps. This call for heat may be controlled

by an optional remote thermostat or through the built-

in Intelliswitch™ thermostat located on top of the air

curtain. Piping should be done in accordance with local

codes, regulations and standard practices. Connect

the building system to the (3/4"-AC08 or 1"- AC10) MPT

supply and return header connections. See Figure 8.
