Mitsubishi Electronics PL24FK21 OC194-53, Individual Control by Grouping the Remote Controllers

Page 53

NOTE1 : Install the relay box where you can be serviced it easily.

NOTE2 : For control circuit wiring, use a wire of No. 14 AWG or a control cable according to the power supply of control circuit.

NOTE3 : When the power supply of the control circuit is 208/230V AC,

Do not connect the control circuit wire to the remote controller cable directly.

Do not place the control circuit wire and the remote controller cable into the same conduit tube.

4-2 Basic wiring

Caution : Before starting all units simultaneously by the remote ON-OFF switch, be sure to connect a sequence-start timer into the remote ON-OFF circuit. Otherwise, a rush of starting current may damage the power supply.

5. INDIVIDUAL CONTROL BY GROUPING THE REMOTE CONTROLLERS

Grouping the remote controllers allows individual control and cen- tralize monitoring of units installed in different places without a spe- cial control board.

Remote control cables are extendible up to 550 yards When the cable length exceeds 33ft, use the double-insulated two-care cable such as Belden 9407. Also, the cable thickness must be No. 22 AWG or above.

When gathering the power ON/OFF switches of air conditioners near the remote controllers, you should also install the power ON/OFF switch near each unit to prevent electric trouble during servicing.
