• The voltage on the compressor terminals must not deviate more than 10% of the
nominal voltage.
It is however highly recommended to keep the voltage drop over the supply cables
at nominal current below 5% of the nominal voltage (IEC 60204-1).
• If cables are grouped together with other power cables, it may be necessary to use
cables of a larger size than those calculated for the standard operating conditions.
• Use the original cable entry. See section
To preserve the protection degree of the electric cubicle and to protect its
components from dust from the environment, it is mandatory to use a proper
cable gland when connecting the supply cable to the compressor.
• Local regulations remain applicable if they are stricter than the values proposed
below.
• Currents are calculated with the full service factor, but we suggest to add 10% due
to over- and under-voltage. Fuses are maximum allowed values for full service
factor and 10% over- and under-voltage.
• Causion
• Always double check the fuse size versus the calculated cable size. If
required, reduce the fuse size or enlarge the cable size
• Cable lenght should not exceed the maximum lenght according to IEC60204
