WARNING Indoor equipment is not designed to withstand
water or moisture. If water does penetrate the
chassis, it could cause equipment damage and/
or create a safety hazard.
Cabling
Wiring is subject to extremes of temperature, humidity, and
vibration. MRC recommends the following general practices be
performed at all installations.
CAUTION Be sure the power being supplied matches the
power required by the equipment.
CAUTION Power supply cords and cables must be
protected. Do not run cords where they can be
stepped on. Protect cables against pinching and
chafing. Pay special attention to locations where
the cables enter or exit an enclosure or make a
sharp bend.
CAUTION Ensure that the electrical supply is protected by
over-current protection devices as required by
the applicable electrical codes.
• Secure all cables at close intervals along their entire
lengths.
• Protect cabling with added sheathing or padding
anywhere cabling passes through a hole or lies against an
obstruction.
• Provide flex relief at any location where the cable must
change direction sharply, to maintain a smooth bend and
prevent kinking.
• Provide strain relief at each connector to absorb any
pulling forces on the cable and prevent damage to the
connector.
