Installation Instructions
1)
Chargers without RCCB or RCBO included in the enclosure must have Residual Current
protection and must be protected with a max 32A fuse in the supply distribution box.
2)
Chargers without RCCB Type B fitted or DC fault protection in the enclosure must in
accordance to IEC 60364-7-722 be protected with a Residual Current Device (RCD) Type B.
3)
3-phase chargers equipped with a Residual Current Circuit Breaker (RCCB) must be protected
with a max 32A fuse in the supply distribution box.
4)
1-phase chargers fitted with a Residual Current Breaker with Overcurrent Protection (RCBO)
can be connected in parallel. This group of chargers must be protected by a backup fuse in
the distribution box. The backup fuse shall not exceed 125A.
• Calculate to determine the maximum operating current. Use conductors that are sized in
accordance with local wiring regulations. The selected cable must be able to sustain periods of
constant load of up to 32A. Manufacturers recommendation is to use minimum 6mm² conductors.
• Calculate the distance to ensure minimal voltage drop.
