9.1
Electric cable size
Attention
The voltage on the compressor terminals must not deviate more than 10% from 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.
The compressor is delivered with 3 m (10 ft.) cable and a fitting cable gland.
This cable gland is necessary to ensure the protection degree of the electric cubicle and
to protect its components from dust from the environment.
Local regulations remain applicable if they are stricter than the values proposed below.
