(1): current in the supply lines at maximum load and nominal voltage
(2): rating of motor circuit breaker with thermomagnetic release characteristic D with residual current device
(to be installed by customer).
Q2: fan motor overload setting
NOTE: The supply line cable delivered with the compressor MUST be protected by raceway or by a suitable
conduit system.
Possible configurations
There are 3 possible configurations:
• (1): Single supply cables. (For DOL and VSD versions, only K21 is used).
• (2): Parallel supply cables
• (3) is only valid for Y-D versions
Cable sizing according IEC
The tables below indicate the current carrying capacities of cables for 3 commonly used installation methods,
calculated according to standard 60364-5-52 - electrical installations of buildings part 5 - selection and erection
equipment and section 52 - current carrying capacities in wiring systems.
The allowed currents are valid for PVC insulated cables with three loaded copper conductors (maximum
conductor temperature 70 °C).
