2 INSTALLATION
2.1 Inspection
A list of all items in the shipment is attached to the shipping container. Inspect the equipment upon arrival for
damage that may have occurred during shipment. All damage claims should be reported to the responsible
shipping agent before installation is attempted. If damage is such that faulty operation is likely to result, the
MicroMod Customer Service Department should be notified.
Inspect the packing material before discarding it as a precaution to prevent loosing mounting hardware or
special instructions that may have been included with the shipment. Normal care in the handling and
installation of this equipment will contribute toward its satisfactory performance.
2.2 Location
The 53IT5100 is supplied with an enclosure designed specifically for indoor mounting. The installation site
selected should be dry, well lighted, and vibration free. The ambient temperature should be stable and
maintained within the specified minimum and maximum temperature limits listed in the Section 1,
specifications of this Instruction Bulletin.
The instrument can be supplied for use with a 24 V dc supply or 120, 220 and 240 V ac line service.
Instrument power requirements are given on the instrument data tag.
2.3 Mounting
2.3.1 General
It is normally not necessary to open the instrument case during installation. If the instrument must be removed
from the case, refer to Section 5 for details. Incorrect procedures may damage the instrument.
The instrument can be flush panel mounted, either as a single unit or side by side. Appropriate mounting
hardware is supplied. Outline dimensions and panel cut-out requirements for case mounting are shown in
Figure 2-1.
The dimensions given for spacing between instruments were selected on the basis of 1/8" thick panel
strength. Panel strength must be considered when multiple case mounting is required. As the panel cut-out
becomes longer it may be necessary to install supporting members. Because the panel area between
instrument rows becomes weaker as the cut-out becomes longer to the point where the panel offers very little
support. It is recommended that the 9 inch minimum center line dimension between horizontally mounted
rows be increased as the number of units increases, or that the panel strip be stiffened.
The rear of the instrument case must be supported to prevent panel distortion. Mount an angle iron or similar
member along the bottom of the cases as indicated in Figure 2-2. If the panel is to be moved the instrument
cases must be tied down to prevent damage.
If multiple mounted instruments are installed in a panel that tilts back, it may be necessary to support the
instruments so the panel does not sag. The downward weight should be supported by additional panel
supports and/or by increasing panel thickness.
