FIGURE 7 - Electrical Connections

NOTE: One Intelliswitch serial cable assembly (part #

505SC***INT485-A) is required for every unit that is to

be used as a master/slave. “***” denotes length of cable

in feet- “008” = 8 feet long.

For Master/Slave operation, a serial cable connection must

be made between the INTELLISWITCH GEN2 control boards

of each unit to be linked.

1. Disconnect power to all the units.

2. Access the wiring tray on top of each unit by removing

the screws that hold the cover in place.

3. Find the (RS485) phone jack couplers in the wiring

trays. There will be two short cables in the wiring

tray of each air curtain, each with a double ended

female phone jack coupler attached to the cable.

4. The serial cable ordered for each unit will be coiled up

in the wiring tray of the unit and connected to one of

the couplers.

Note: There may be one less serial cable than the

number of units ordered. e.g. Two units together will

need only one cable; three units together will need two

cables, etc. Any extra cables can be kept as spares.

5. Use one of the extra electrical knockouts to route serial

cable from one unit to the next. Be sure to protect the

edge of the knockout properly.

6. Plug (RS485) male phone jack on the end of the serial

cable into the empty coupler on the next unit.

7. Continue process for all units that are to be connected

serially.

8. Serial cable connections are capable of two way com

munication. It does not matter which coupler the

cables are connected to.

9. The rst and last air curtains in the group will each

have an empty coupler after all connections are made.

So if there are only two air curtains connected, each

will have an empty cable coupler.
