Electrical Connection; General Information - Wolf BWL-1S-05 Installation And Operating Instructions Manual

20 Electrical connection
20.1 General information
The installation may be carried out only by an approved electrical contractor. Observe
VDE regulations [Germany] and all local regulations of your power supply utility.
An omnipolar isolator with at least 3 mm contact separation must be integrated in the
power cable upstream of the appliance.
If using residual current protection (ground fault circuit interrupter or RCD), use a type
B AC/DC-sensitive residual current protective device, as this is the only type suited to
DC residual currents.
Type A residual current protective devices are not suitable.
Do not route sensor leads alongside 230 V or 400 V cables.
Danger through 'live' electrical components.
Please note: Turn OFF the ON/OFF switch before removing the casing.
Never touch electrical components or contacts when the ON/OFF switch is in the ON position.
There is a danger of electrocution, resulting in a risk to health or death.
The main terminals are "live", even when the ON/OFF switch is in the OFF position.
During servicing and installation work, isolate the entire system from the power supply
across all poles, otherwise there will be a risk of electrocution.
Before connecting the appliance to the power supply, ensure that all electrical covers and
protective devices are fully installed.
Connecting cables, installation ducts or tubes, etc., must be weatherproof, UV-resistant and
protected from mechanical damage.
