6.2.2 Receiver Location
To ensure safe and reliable system operation, the following items must be considered when selecting a location
for mounting the receiver:
•
Install the receiver in an environment where the ambient temperature during operation does not drop
below -20º F (-28º C) or rise above +160º F (+71º C)
•
To ensure that the receiver enclosure is electrically at earth ground, connect the green wire in the
interface cable to earth ground
•
Mount the receiver enclosure securely using appropriate locking-type hardware

Installation Wiring
WARNING
Before starting this installation, ensure that the crane power has been disconnected and that all
applicable safety precautions are followed.
CAUTION
Connection to equipment or contactors with higher voltage or current requirements requires
intermediate relays.
6.4
Output Snubbers
Snubbers are recommended for the suppression of noise generated from arcing relay contacts. When a contactor
opens, the contactor coil produces a large voltage potential, much like automotive ignition systems. When the
points open on automotive ignition systems, the coil sends a large voltage to the distributor. This voltage jumps
across the spark plug (called
arcing
). The result is a large amount of noise generated in the system.
A snubber is a device designed to reduce arcing (noise). To increase relay life, it is recommended that all
contactors have snubbers installed directly across the coils. If more snubbers are needed, see the
or contact Cattron at
