Gas compression fittings
▷
The seals in some gas compression fittings
are approved for temperatures of up to 70°C
(158°F). This temperature limit will not be ex-
ceeded if the flow through the pipe is at least
1 m
3
/h (35.31 SCFH) of gas and the maximum
ambient temperature is 50°C (122°F).

Wiring
WARNING
Attention! Please observe the following to ensure
that no damage occurs:
– Electric shocks can be fatal! Before working
on possible live components, ensure the unit
is disconnected from the power supply.
– The solenoid actuator heats up during opera-
tion. Surface temperature approx. 85°C (approx.
185°F) pursuant to EN 60730-1.
▷
Use temperature-resistant cable (> 80°C/176°F).
▷
Wiring to EN 60204-1.
Disconnect the system from the electrical power
supply.
Shut off the gas supply.
▷
The solenoid actuator can be rotated to allow
it to be repositioned for electrical connection.
On VG..N, the hexagonal nut/cap on the solenoid
actuator must be loosened for this.
