Notes: 1. If you acquire UL standard with this device, please use the above-mentioned fuse.
This product can cause a d.c. current in the
rotective conductor. Where a residual current device
(RCD) is used for
protection in case of direct or indirect contact, only an RCD of Type B is
allowed
on the supply side of this product. Otherwise, another protective
measure shall be applied, such as
separation from the environment by
double or reinforced insulation, or isolation from the supply
system by a
transformer.
Fault current waveform
The drive does not have a built-in ground protection circuit. Install a ground-fault interrupt
circuit with short-circuit protection or a ground-fault interrupt circuit for ground protection
together with a circuit breaker if safety is of high priority in the system.
