TROX cannot guarantee leak-free dampers if the
actuators are provided and installed by others.
Connecting electric actuators
Personnel:
Skilled qualified electrician
Use only cables that are designed for the supply
voltage for which they will be used. The power
rating is given on the actuator rating plate. The
length and cross section as well as any contact
resistance may increase voltage losses.
A skilled qualified electrician has to select the cor-
rect cable types and sizes.
DANGER!
Danger of electric shock! Do not touch any live
components! Electrical equipment carries a dan-
gerous electrical voltage.
–
Only skilled qualified electricians are allowed
to work on the electrical system.
–
Switch off the power supply before working
on any electrical equipment.
Connect the actuator as indicated on the
actuator or in the manufacturer's product
documentation.
