ted parts carrying mains voltage the-
re is a risk of electric shock including
injury or death!
Measures:
Observe all the valid rules and regu-
lations for electrical installation !
The removed control unit does no lon-
ger have IP protection and must be pro-
tected from damp!
CAUTION! Maintenance work must only
be carried out when the device is in a
de-energized state! Any work involving
electrical parts must only be performed
by suitably qualified and authorized per-
