V. ELECTRICAL CONNECTIONS
VI. FIELD CONNECTIONS
All electrical wiring and connections
MUST
be performed by
qualified personnel in accordance with the latest edition of the
National Electrical Code ANSI/NFPA No. 70 or, in Canada, the
Canadian Electrical Code, Part 1-C.S.A. Standard C22.1 and local
codes and regulations.
MAKE SURE THE CORRECT
VOLTAGE AS MARKED ON THE UNIT IS USED.
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
junction box.
See Figure 7.
B.
All field wiring must be copper with a minimum
insulation of 60°C within approved conduit. If any of the
wire supplied with the unit must be replaced, it must be
replaced with copper wiring with a minimum insulation
of 90°C.
C.
Electric, steam and hot water heated air curtains are
factory equipped with an air curtain mounted solid state
temperature sensor cable located in the junction box.
Depending on where the temperature is to be measured,
the sensor may be left on the endplate or positioned
elsewhere. Do not put any clamps on the rubber coated
tip.
D.
Remove the junction box cover.
E.
Connect all supply and control circuit wires according to
the wiring diagram provided.
NOTE: For Electric heated air curtains provided with
the optional remote thermostat, mount and wire the
thermostat according to thermostat instructions and wiring
diagram.
For Serial Network Connection
(previously Master/
Slave Connection)
– see Appendix A, “Serial/Network
Connection.”
NOTE: The air curtain must have been
ordered from the factory with this option.
For Remote Mounted Display Faceplate
– If operation of the
Intelliswitch™ is to be through a Factory Ordered Remote
Mounted Display Faceplate, see Appendix B, “Remote
Mounted Display Faceplate.”
For Electric, Steam 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 a remote
thermostat or manually through the Intelliswitch™
located on the discharge side 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 junction box).
See Figure 7.
