Wiring

WARNING
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is discon-
nected from the power supply.
▷ The solenoid actuator heats up during operation
depending on ambient temperature and voltage.
> +80 °C
▷ The rectifier adapter must be installed.
▷ Use temperature-resistant cable (> 80°C).
 Disconnect the system from the electrical power
supply.
2 Shut off the gas supply.

Tightness test

CAUTION
Please observe the following to ensure that the VGP
is not damaged during the tightness test:
– Check max. inlet pressure – see type label.
– Test pressure ≤ 1.5 x max. inlet pressure.
 Close the solenoid valve.
2 To be able to check the tightness, shut off the
downstream pipeline as close as possible to the
valve.
