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
2
).
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.
The instrument conforms to Mains Power Input Insulation Category 2, Pollution Degree 2 (EN601010–1).
(This equipment is protected through double insulation – Class II.)
All connections to secondary circuits must have basic insulation.
After installation, there must be no access to live parts, e.g. terminals.
Terminals for external circuits are for use only with equipment with no accessible live parts.
If the instrument is used in a manner not specified by the Company, the protection provided by the equipment may
be impaired.
All equipment connected to the instrument's terminals must comply with local safety standards
(IEC 60950, EN601010–1).
