Warning.

The transmitter 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 fitted in close
proximity to the instrument within easy reach of the
operator and must be marked clearly as the
disconnection device for the transmitter - see IM/
AZ20E-EN.

Electrical installation and earthing (grounding) must be
in accordance with relevant national and local
standards.

Remove all power from supply, relay and any powered
control circuits and high common mode voltages
before accessing or making any connections.

The Endura AZ25 cable carries the screened signal
wires Do not use alternative wires.

The equipment conforms to Installation Category II of
IEC 61010.

All connections to secondary circuits must have basic
insulation.

After installation, there must be no access to live
parts, for example, terminals.

Terminals for external circuits are for use only with
equipment with no accessible live parts.

If the equipment is used in a manner not specified by
the Company, the protection provided by the
equipment may be impaired.

All equipment connected to the transmitter's terminals
must comply with local safety standards (IEC 60950,
EN601010-1).

Caution.

Make connections only as shown.

Maintain Environmental Protection at all times.

Ensure the seal and mating surfaces are clean to
maintain environmental rating.

Ensure cable glands are tightened after wiring. Do not
overtighten the plastic cable glands to avoid
destroying their sealing properties. Initially, tighten
finger-tight, then a further
suitable spanner or wrench.

Fit blanking plugs where required.

Inductive loads must be suppressed or clamped to
limit voltage swings.

Operation of outputs is programmable.
