Figure 1. Installation dimensions for LH2 enclosure.
Suitability for the Installation—To determine if a unit’s
area classification approvals are appropriate for a
particular installation, first inspect the classification
labeling on the instrument and/or instrument enclosure
and the “Control Drawing for Installation” found in the
User’s Manual (where applicable). Second, consult the
installation criteria for the approval or electrical standard
agencies governing your location to determine if the
unit’s approvals are suitable for the installation. If the
instrument’s labeling matches the agency criteria and/or
electrical codes for the area, the unit is suitable for the
installation. To determine if the unit’s electrical and
environmental specifications are appropriate for the
installation, consult the “Specifications” table in the
User’s Manual for that instrument. If the instrument’s
electrical and environmental characteristics are within
the expected ambient operating conditions for the
installation, the instrument is suitable for the installation.
CAUTION
If for any reason you are uncertain as to whether the
instrument’s specifications or area classifications meet
the operational or safety requirements for the installation,
consult Moore Industries prior to installation.
Installation of LH Enclosure Apparatus
1. Install the LH2 enclosure onto a surface, temperature
thermowell, or onto a standard 2-inch pipe using the
mounting hardware. Remove the cap from the LH2 by
rotating the cap counter clockwise after unlocking by
rotating the locking screw clockwise.
2. Connect input and output wiring in accordance with the
connection information found in the User’s Manual for
that instrument.
3. Replace the cap to the LH2 by rotating the cap
clockwise. Secure (lock) the cap by rotating the
locking screw counterclockwise.
4. Connect a ground wire between the ground screw on
the LH2 enclosure to an appropriate earth ground.
Ground Wire Recommendations
The following ground wiring practices must be followed
to ensure proper performance of the Moore Industries
instrument in any application.
• Any Moore Industries product in a metal case or
housing must be grounded.
• All input signals to, and output signals from, Moore
Industries’ products should be connected using a
shielded, twisted pair technique. Shields should be
connected to an earth or safety ground at the unit itself.
• The maximum allowable length of any unshielded
portion of the input and/or output connections is 2
inches (50.8mm).
See the User’s Manual for the instrument for additional
installation information.
