WARNING
Bodily injury.
• 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.
• The probe must be bonded to local earth using the
external earth connection – see Figure 11.
• 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 AZ10 cable carries the screened signal wires and the
separately screened 90 to 264 V AC heater wires safely. 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).

NOTICE
Earth bonding between the probe and transmitter is
required to ensure effective EMC compliance. Min. 4mm2
cable should be used.
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.
