• If the flowmeter is protected by the optional transient protector, you
must provide a high-current ground connection from the electronics
housing to earth ground. Also, tighten the ground screw in the bottom
center of the terminal block to provide a good ground connection.
• Plug and seal all unused conduit connections on the electronics
housing to avoid moisture accumulation in the terminal side
of the housing.
• If the connections are not sealed, mount the flowmeter with the conduit
entry positioned downward for drainage. Install wiring with a drip loop,
making sure the bottom of the drip loop is lower than the conduit
connections or the electronics housing.
