NSTALLATION
Earth connection
Connector type: M5 bolt
An earth wire of at least 6mm
2
must be attached via a crimp on ring terminal to the dedicated
M5 earth bolt on the case of the gauge.
Do not rely on the mounting bolts to provide a reliable earth path.
If a height stand is used then it must also be earthed via its own dedicated earth wire.
All earth wires should be kept as short as possible.
Shielded Cables
Use shielded cable for all signal connections.
Ensure that all cable shields are correctly clamped and electrically connected to their
connectors and metal connector shells at both ends.
Ensure that the shields of cables conn
ecting to the end user’s
equipment are clamped to
earth at their destination.
