Contact an electrical installer!
*Specialist knowledge required for installation:
The following specialist knowledge is particularly important during
installation:
•
The “5 safety rules” to be used:
Disconnect from mains; Safeguard from switching on
again; Check that system is deenergised; Earth and short
circuit; Cover or cordon off neighbouring live parts;
•
Select suitable tool, measuring equipment and, if neces-
sary, personal safety equipment;
•
Evaluation of measuring results;
Selection of electrical installation material for safeguard-
ing shut-off conditions;
•
IP protection types;
•
Installation of electrical installation material;
•
Type of supply network (TN system, IT system, TT sys-
tem) and the resulting connecting conditions (classical
zero balancing, protective earthing, required additional
measures etc.).
Installation may only take place in normal com-
mercial switch boxes (device boxes) in accord-
ance with DIN 49073-1.
The device may only be operated with adapters
and an associated, fitted switch cover. The switch
cover may only be removed during configuration.
Please observe the hazard information in section
„2 Hazard information“ on page 35 during in-
stallation.
A minimum load of 1 W is required for operation
