Warning.

The instrument is not fitted with a switch therefore a disconnecting device such as a switch or circuit breaker
conforming to local safety standards must be fitted to the final installation.

It must be mounted in close proximity to the instrument within easy reach of the operator and must be marked clearly
as the disconnection device for the instrument.

Remove all power from supply, relay and any powered control circuits and high common mode voltages before
accessing or making any connections.

Use cable appropriate for the load currents. The terminals accept cables from 18 to 14 AWG (0.8 to 2.5 mm

Always route signal leads and power cables separately, preferably in earthed (grounded) metal conduit.

It is strongly recommended that screened cable is used for signal inputs and relay connections.
