5. Wiring

In this Chapter, the wiring necessary for connection to the EXAxt ZR Separate type Zirconia

Oxygen Analyzer is described.

5.1 General

CAUTION

• NEVER supply current to the converter or any other device constituting a power circuit in

combination with the converter, until all wiring is completed.

• This product complies with CE marking.

Where compliance with CE marking is necessary, the following wiring procedure is necessary.

1.Install an external switch or circuit breaker to the power supply of the converter.

2. Use an external switch or circuit breaker rated 5 A and conforming with IEC 947-1 or

IEC 947-3.

3. It is recommended that the external switch or circuit breaker be mounted in the same room as

the converter.

4. The external switch or circuit breaker should be installed within the reach of the operator, and

marked as the power supply switch of this equipment.

Wiring procedure

Wiring should be performed according to the following procedure:

1. Be sure to connect the shield line to FG terminal of the converter.

2. The outer sheath of the signal line should be stripped to a length of 50 mm or less.

The most outer sheath of the power cable should be stripped to a length of 20 mm or less.

3. Signals may be affected by noise if signal lines, power cable and heater cable are located in

the same conduit. When using conduit, signal lines should be installed in a separate conduit

than power and heater cables.

4. Install metal blind plug(s) in unused cable connection gland(s) of the converter.

5. Metal conduit should be grounded.

6. The following cables are used for wiring:
