4.6 Electrical Connections

Warning.

The analyzer is not fitted with a switch therefore an isolation 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 analyzer within easy reach of
the operator and must be marked clearly as the disconnection device for the analyzer.

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 3 A and 75 °C (167 °F) minimum, and voltage: 100 / 240 V
that conform to either IEC 60227 or IEC 60245, or to the National Electrical Code (NEC) for the US, or the Canadian
Electrical Code for Canada. The terminals accept cables 0.8 to 2.5 mm2 (18 to 14 AWG).

Ensure the correct fuses are fitted – Fig. 4.8, page 19, for fuse details.

Use screened cable for signal inputs and relay connections.

Replacement of the internal battery (type Varta CR2025 3V lithium cell) must be carried out by an approved technician only.

The analyzer conforms to Installation Category II of IEC 61010.

All connections to secondary circuits must have insulation to required local safety standards.

After installation, there must be no access to live parts, for example, terminals.

If the analyzer is used in a manner not specified by the Company, the protection provided by the equipment may be
impaired.

All equipment connected to the analyzer's terminals must comply with local safety standards (IEC 60950, EN61010-1).

Route signal leads and power cables separately, preferably in an earthed (grounded) flexible metal conduit.

The ethernet and bus interface connectors must only be connected to SELV circuits.
USA and Canada Only

The supplied cable glands are provided for the connection of signal input and ethernet communication wiring ONLY.

The supplied cable glands and use of cable / flexible cord for connection of the mains power source to the mains input and
relay contact output terminals is not permitted in the USA or Canada.

For connection to mains (mains input and relay contact outputs), use only suitably rated field wiring insulated copper
conductors rated min. 300 V, 14 AWG, 90C. Route wires through suitably rated flexible conduits and fittings.
