Electrical connection
DANGER!
Risk of fatal electric shock!
All electrical connection work must be carried out
by qualified electricians only.
Before opening the unit, disconnect the system
from the power supply and prevent it from being
switched back on again!
WARNING!
Note and follow the relevant EN, VDE and/or local
safety regulations during installation and when car-
rying out electrical work.
Note and follow the technical connection condi-
tions of the responsible power supply company!
WARNING!
Only qualified personnel (trained heating or refrig-
eration engineer or electrician) may carry out work
on the unit and its components.
CAUTION!
A cable with a small cross-section reduces the approved
length of the connection cable. If the cable is too long the
RBE may not work!
ATTENTION
Electrical work on the room control unit may only be car-
ried out by the authorised service personnel or specialised
firms, which have been authorised by the manufacturer.
