9 Technical data
9.1 Electric cable size and fuses
Important
• 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 Dimension drawings .
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.
• Caution
• Always double check the fuse size versus the calculated cable size. If
required, reduce the fuse size or enlarge the cable size
• Cable length should not exceed the maximum length according to IEC60204
