WARNING
Electric shocks can be fatal!
–
Before working on electrically live components,
ensure they are disconnected from the power
supply.
–
It must be possible to isolate the actuator from
the power supply. Provide a double pole switch.
▷
Install supply and signal lines separately.
▷
Conductors which have not been connected
(spare conductors) must be insulated at their
ends.
▷
Cables should be installed well away from high-
voltage lines of other devices.
▷
Observe EMC Directive for installation of signal
lines.
▷
If the power supply is susceptible to frequent
voltage peaks, we recommend that an electric
filter be used.
▷
Use temperature-resistant supply cables (≥ 90°C
and min. 1 – 1.5 mm² or AWG 14 – 18).
▷
Use cables with wire end ferrules.
▷
Cable cross-section: max. 2.5 mm².
▷

and outputs, see www.docuthek.com

Disconnect the system from the electrical power
supply.
Shut off the gas supply.
▷
Before opening the unit, the fitter should ground
himself.

Do not connect power supply and digital inputs
to different phases of a three-phase current sys-
tem.
