Hazardous Area Oxymitter 4000
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-
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 O
2
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.
