8.2 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 IP 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.
•
Caution:
•
Always double-check the fuse size versus the calculated cable size. If required,
reduce fuse size or enlarge cable size.
•
Cable length should not exceed the maximum length according to IEC60204 table
10
Leakage breaker (optional)
If the installation requires a leakage breaker, always use an all current sensitive leakage breaker, RCM or
RCD Type B (according to IEC/EN 60755) with a sufficient trip level.
