Installation 5-3 SCM4000 Technical Reference Manual
WARNING Follow instructions carefully. Do not place
the equipment on an unstable support such
as a cart, stand, or table. The equipment

2. Install the two bottom screws first. Use lock washers to
prevent loosening. Tighten securely.
3. Install the top two screws. Use lock washers to
prevent loosening. Tighten securely.
5.5.3 Ventilation
CAUTION Temperatures inside a closed mounting
area can be significantly higher than the
ambient temperature. Always allow
adequate ventilation.
• If possible, install the SCM4000 in a climate-controlled
area.
• Installation should allow adequate air flow around the
equipment. Air flow should be circulated and mixed with
room air, not trapped in a closed space.
• When mounting the SCM in an enclosed rack with other
equipment, it is good practice to allow spaces at the top
and bottom of the rack, and to fill those spaces with
grillwork instead of blank panels.
5.5.4 Moisture
WARNING Indoor equipment is not designed to
withstand water or moisture. If water does
enter the chassis, it could cause equipment
damage and/or create a safety hazard.
• Locate the equipment in an area protected from dripping
water or excessive humidity.
5.5.5 Cabling
In mobile installations, wiring is subject to extremes of
temperature, humidity, and vibration. MRC recommends the
following general practices be performed in all installations.
