Hazardous Area Oxymitter 4000

Instruction Manual

IB-106-340C Rev. 4.1 July 2004

2-3 ELECTRICAL INSTALLATION (FOR HAZARDOUS AREA OXYMITTER 4000 WITH REMOTE ELECTRONICS)

All wiring must conform to local and national codes.

Disconnect and lock out power before connecting the unit to the power supply.

Install all protective equipment covers and safety ground leads after installa- tion. Failure to install covers and ground leads could result in serious injury or death.

To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation of this equipment, con- nection to the main electrical power supply must be made through a circuit breaker (min 10 A) which will discon- nect all current-carrying conductors during a fault situation. This circuit breaker should also include a me- chanically operated isolating switch. If not, then another external means of disconnecting the supply from the equipment should be located close by. Circuit breakers or switches must comply with a recognized standard such as IEC 947.

The probe and probe abrasive shield
are heavy. Use proper lifting and car-	2
rying procedures to avoid personnel
injury.

To maintain explosion-proof protec- tion, all cable entry devices and blanking elements for unused aper- tures must be certified flameproof, suitable for the conditions of use and be properly installed.

a.Remove screw (18, Figure 9-4), cover lock (19), captive washer (20), and left side blind cover (17) from the remote electronics.

b.Connect Line Voltage. Connect the line, or L1, wire to the L1 terminal and the neutral, or L2 wire, to the N terminal (Figure 2-10).

The Hazardous Area Oxymitter 4000 will automatically configure itself for 90-250 VAC line voltage and 50/60 Hz. To avoid a shock hazard, the power terminal cover must be installed.

c.Connect 4-20 mA Signal and Calibration Handshake/Logic I/O Leads (Figure 2-10).

1.4-20 mA Signal. The 4-20 mA signal represents the O2 value and can also operate the Model 751 Loop LCD Dis- play or any other loop powered display. Superimposed on the 4-20 mA signal is HART information that is accessible through a Model 275/375 Handheld Communicator or AMS software.
