3-1 GENERAL
a. Verify Mechanical Installation
Ensure the Hazardous Area Oxymitter 4000
is installed correctly. See Section 2,
INSTALLATION.
Opening the electronics housing in
hazardous areas may cause an explo-
sion causing severe injury, or death.
It may be required to get a hot work
permit from your company safety offi-
cer before you open the housing.
b. Verify Terminal Block Wiring
1. Remove screw (18, Figure 9-3 or
Figure 9-4), cover lock (19), and cap-
tive washer (20) that secure cover (17)
on left side of housing (11). Remove
the cover.
2. Check the terminal block wiring
(Figure 3-1). Be sure the power, the
4-20 mA signal, and the logic outputs
are properly connected and secure.
To avoid a shock hazard, the power
terminal cover must be installed.
For units with remote electronics,
check the terminal block wiring at the
probe and at the remote electronics
unit.
3. Install the cover (17, Figure 9-3 or
