Initial Setting - Daikin VRV BSF4Q54TVJ Manuel D'installation

CAUTION
• When fastening the wire, use the included clamp (Accessory (1)) so as not to apply tensile force to the
wire connection and then securely fasten the wire.
Also, after the wiring is completed, organize the wiring so that the control box cover does not pop up
and then properly replace the control box cover.
Make sure no wires are pinched when replacing the control box cover.
Always use the wire through hole to protect wires.
• Do not pass the transmission wiring and power supply wiring
through the same locations, and outside of the unit keep them sep-
arated by at least 2 in. (50 mm).
Not doing so could cause the transmission wiring to pick up electric
noise (external noise) and result in a malfunction or breakdown.
• As shown in the figure on the right, wrap the transmission wiring
between each Branch Selector unit and indoor unit with finishing
tape (to be supplied in the field).
