9. Technical Data
9.1 Electric information
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.

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.

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.
