Point (HmIPW-DRAP) to enable power supply for the device.
Before installation, please note the device number (SGTIN) labelled
on the device as well as the exact application purpose in order to
facilitate later allocation. You can also find the device number on the
QR code sticker supplied.
Installation may only take place in normal commercial switch boxes
(device boxes) in accordance with DIN 49073-1.

sonal safety equipment;
•
Evaluation of measuring results;
•
Selection of electrical installation material for safeguarding shut-
off conditions;
•
IP protection types;
•
Installation of electrical installation material;
•
Type of supply network (TN system, IT system, TT system) and
the resulting connecting conditions (classical zero balancing,
protective earthing, required additional measures etc.).
