– MCA: Max circuit amps (A)
– TOCA: Total overcurrent current amps (A) for each OC set
– MFA: Max fuse amps (A). It is used to select the main overcurrent and dierential switches
– MSC: Max starting current (A) of the compressor
– RLA: Rated load amps (A). It is based on the following conditions: indoor temperature 27 °C DB, 19 °C WB, outdoor
temperature 35 °C DB.
– OFM: Outdoor fan motor
– FLA: Full load amps (A)
– KW: Rated motor output (kW)
The units are suitable for use with electrical systems where the voltage supplied to the unit terminals is not below or
above the given range limits. The maximum allowed voltage variation between phases is 2%
Select the cable size according to the MCA value
a
CAUTION
Appliances in compliance with IEC 61000-3-12.
The fixed wiring must incorporate an omnipolar switch where all active conductors have the minimum contact
spacing required by national wiring regulations.
a
CAUTION
Seal the electrical connections with insulating material to prevent condensate from forming.
Note: Air conditioners can connect to a centralised controller (CCM). Before start-up, connect the cables properly and
set the system address and network address of the indoor units.
