5.1 Electrical Safety

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 transmitter within easy reach of the operator and must be
marked clearly as the disconnection device for the transmitter – see Fig. 5.1, page 19.

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.

Use cable appropriate for the load currents: 3-core cable rated 5 A and 90 °C (194 °F) minimum,
that conform to either IEC 60227 or IEC 60245. The terminals accept cables from 0.8 to 2.5 mm
(18 to 14 AWG).

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, EN61010-1).
