Electrical Wiring
Fig. 7: Pin code: Connection plug / Socket for 5-pin version
Serious injury or death from electric shock may occur if wiring, installation, disassembly or remove of wires is
performed while electrical power is energized.
Always shut off or disconnect electrical power at service panel and lock switch or breaker and tag to prevent energizing
electrical power during work or while Flowmeter is not assembled and installed.
Wiring installation, disassembly and removal must be performed by qualified persons experienced and knowledgeable
about electrical work.
