Power, input and output (I/O) wiring must be in accordance with the area classification for which it is used (Class I, Div 1). For North America, installations must be per the U. S. National Electrical Code, NFPA 70, or the Canadian Electrical Code in order to maintain Class I, Division 1 ratings. This may require using connections or other adaptations in accordance with the requirements of the authority having jurisdiction.

WARNING: Explosion Hazard - Substitution of components may impair suitability for Class I, Division 1 applications.

WARNING: Explosion Hazard - When in hazardous locations, turn power OFF before replacing or wiring modules.

WARNING: Explosion Hazard - Do NOT disconnect equipment unless power has been switched OFF or the area is known to be Non-Hazardous.

For positive ground installation, contact the Liquid Controls Service Department

Solenoid operated valve 81527 (3-way LPG solenoid) has 3 cablespotted into the housing. All other solenoid operated valves on LiquidControls valves use cable assembly81859, which has 2 cables.

The Earth grounds for Terminals 16& 19 are optional. The solenoid operated valves are grounded through the component they aremounted on.

ESD PRECAUTION OPENING LECTROCOUNT REGISTERSBefore opening the LectroCount register and handling the CPU board, it is important to discharge any ESD that may have built up on your person. To discharge ESD from your person, touch a well-grounded point such as the LectroCount register housing, the meter, the truck piping, or the bumper. When the maintenance is complete and the LectroCount register door is closed, the CPU board is protected from ESD by the LectroCount register housing which is grounded to the chassis.
