Micromod Micro-DCI: 53IT5100A Indicator/Totalizer - Manual (Page 19)

2.0 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 re-
ported 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 hard-
ware 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 Indicator/Totalizer 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 maxi-
mum 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 serv-
ice. 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 in-
strument.
The instrument can be flush panel mounted, either as a single unit or side by side in multiple fash-
ion. Appropriate mounting hardware is supplied. Outline dimensions and panel cut-out re-
quirements 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 di-
mension 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 sup-
port the instruments so the panel does not sag. The downward weight should be supported by ad-
ditional panel supports and/or by increasing panel thickness.
