Example Of Wiring Entire System; Procedure For Incoming Wiring - Daikin CONVENI-PACK Installation Manual

7-1 Example of Wiring Entire System

Note:1. For Remote switch, use non-voltage contact for microcurrent (not more than 1mA, 12VDC)
Note:2. Total capacity for warning, alarm : 0.5A or less at AC 220 to 240V.
Capacity for operation output : 0.5A or less at AC 220 to 240V.

Note
• Use conduit for power supply wiring.
• Make sure the weak electric wiring (i.e. for the remote controller,
between units, etc.) and the power wiring do not pass near each
other, keeping them at least 50 mm apart.
Proximity may cause electrical interference, malfunctions, and
breakage.
• Be sure to connect the power wiring to the power wiring terminal
block and secure it as described in "7-2 Procedure for Incoming
Wiring".
• Do not connect the power supply to the terminal block for the
transmission wiring for warning, alarm, operation output, and
remote operation switch. Otherwise the entire system will be dam-
aged.
• Transmission wiring should be secured as described in
"7-3 Procedure for Power Supply Wiring".
• Secure wiring with clamp such as insulation lock ties to avoid con-
tact with piping.
• Shape the wires to prevent the structure such as the control box
lid deforming. And close the cover firmly.

7-2 Procedure for Incoming Wiring

• Route high-voltage wiring (power supply wiring, earth wires, and
warning/alarm/operation wiring) through wiring openings located
on the side or front of the unit (knock holes) or on the bottom
frame (knock holes).
• Route low-voltage wiring (for remote operating switches) through
wiring openings (knock holes) located on the front of the unit or
through wiring intakes.

Note
• Open the knock holes with a hammer or the like.
• After knocking out the holes, we recommend you remove any
burrs and paint them using the repair paint to prevent rusting.
