DANGER
There is a risk of serious injury or death when working
on live components.
- Switch off the power supply to the device for installation and assembly work.
- Secure the switched-off supply voltage against unintentional reconnection by other
persons.
- Check that the supply line is voltage-free before starting installation and assembly work.
ALL-CURRENT SENSITIVE RESIDUAL CURRENT CIRCUIT
BREAKER (FI TYP B)
Depending on the equipment, the power distributors can be equipped with a
residual current circuit breaker (FI/RCD) "Type B", which are only intended for
certain applications.
WARNING
For safe use, it is essential to observe the following instructions!
The affected devices are marked accordingly with a sticker:
WARNING
Power distributors with universal current sensitive residual current circuit
breakers must not be operated behind pulse current sensitive residual current
circuit breakers (with RCD type A). When used, a residual current circuit breaker
(FI/RCD) type B must always be connected upstream.
Electrical equipment or consumers (e.g. welding equipment, pumps, vibrating
machines, etc.) that are controlled via a frequency converter can generate
smooth DC residual currents.
Commercially available residual current circuit breakers with the tripping
characteristic AC or of type A cannot detect these residual currents, so that
proper tripping of the RCD is not guaranteed and the risk of electric shock
increases in the event of a fault.
Contact a qualified electrician.
Before using the device, have the electrical installation checked by a qualified
electrician to ensure that you can operate the device or the loads to be
connected.
After a residual current circuit breaker has tripped, all circuit breakers in the
circuit of the electrical system, including those of the supply point used,
must be tested for function and effectiveness by a qualified electrician.
Please observe the country-specific regulations.
