2.2 - CPI SWITCH INSTALLATION and CALIBRATION
It is necessary to work in a non-explosive atmosphere and shut off the gas before installation.
• ATTENTION:
The device is supplied with a 3 metre long pre-wired connection cable. This cable
CANNOT
be replaced
with a different one and in the event of damage, the part must be disposed of and replaced with an identical new one; Any
repair (if possible) can only be carried out by the manufacturer;
• In the dangerous zone, wire the ends of the cable with explosion-proof approved equipment (E.g. Terminal box with “E”
protection or increased safety according to EN 60079-7) using the special wire terminals.
• Connect the terminal of the CPI connection cable in series (
