3.4 - GENERAL EXAMPLES OF INSTALLATION
EXAMPLE 1
1. 355AM... Manual reset solenoid valve
2. Jerk ON/OFF valve
3. Gas filter
4. OPSO shut off valve
5. Pressure regulator
6. 355AA... fast opening automatic solenoid valve
7. Solenoid valve control device
8. Relief valve
9. Pressure gauge and relative button
10. Gas detector
11. Remote jerk ON/OFF valve lever control
12. Expansion joint/anti-vibration mount
To wire the solenoid valve (see the images below):
a. Loosen the 4 fastening screws (
1
);
b. Remove the cover (
2
) and loosen the cable gland (
3
);
c. Pass the cable through the cable gland (
3
), leaving a suitable length at the end to facilitate wiring to the terminal
board without tensioning or forcing;
d. Secure the cables (duly crimped) to the terminal board (
31
), connecting terminals 1 and 2 to the power supply and
the earthing cable to the terminal .
IMPORTANT:
respect the polarity with 24 Vdc power supply;
e. Use a 22mm commercial spanner to secure the cable gland (
3
) , ensuring the product has a protection rating of IP65;
f. Secure the cover (
2
) with the 4 fastening screws (
1
). Make sure to place the rubber sealing gasket (
33
) correctly in
order to ensure product rating of IP65;
• The valve needs to be earthed either through the pipe or through other means (eg cable jumpers).
3.3 - INSTALLATION IN PLACES WHERE THERE IS THE RISK OF EXPLOSION (DIRECTIVE 2014/34/EU)
