Option 2: FTC2BR powered by independent source
If FTC2BR and outdoor units have separate power supplies, the following
requirements MUST carried out.
• Remove the short circuited connector CNS2.
• Turn on the outdoor unit before the FTC2BR.
• Outdoor unit DIP switch settings changed to SW8-3 ON.
• Power by independent source is not available for particular models of outdoor unit
model.
For more detail, refer to the connecting outdoor unit installation manual.
Notes:
1. Do not run the low voltage cables through a slot that the high voltage ca-
bles go through.
2. Do not bundle power cables together with other cables.
3. Bundle cables as Fig. 4.1.3 by using clamps.
*1. A breaker with at least 3.0 mm contact separation in each pole shall be provided.
Use earth leakage breaker (NV).
The breaker shall be provided to ensure disconnection of all active phase
conductors of the supply.
*2. Max. 45 m
If 2.5 mm² used, Max. 50 m
If 2.5 mm² used and S3 separated, Max. 80 m
*3. The values given in the table above are not always measured against the ground
value.
Notes:
1. Wiring size must comply with the applicable local and national codes.
2. FTC2BR/outdoor unit connecting cords shall not be lighter than
polychloroprene sheathed flexible cord. (Design 60245 IEC 57)
FTC2BR unit power supply cords shall not be lighter than
polychloroprene sheathed flexible cord. (Design 60227 IEC 53)
3. Install an earth longer than other cables.
