DANGER
NOTICE
34
If the unit is connected to electrical supply mains without a neutral
conductor, a type B fault current circuit breaker (RCD type B), which is
sensitive to all types of current, must be installed.
The unit generates a small fault current through use of special
electronic components. To ensure that the residual current device does
not trip during normal operation, each unit should have its own residual
current device.

The unit can be included in a potential equalization system by means of
appropriately sized wiring.
Risk of personal injury and property damage from electric shock
• Before working on the unit, ensure that the unit is dead.
• Do not operate the unit with the housing open.
Risk of property damage from wrong supply voltage

on the transformer inside the unit.
