Proper Mounting Of Electrical Arc Suppressors {1408,4466}

Usage:


All Machines Using Arc Suppressors

Arc suppressors are used in electrical circuits with solenoids which may discharge inductive loads when the solenoids are de-energized. The purpose of the arc suppressor is to dissipate the discharged energy, so that other components in the circuit are not damaged.

Typical machine applications where an arc suppressor is used include the air conditioner clutch solenoid on many machine models, and the cushion hitch solenoid and bail solenoid on certain Wheel Tractor Scrapers. The 3E-9169, 105-8827, 130-0956, and 130-8134 Arc Suppressor Groups may experience lead wire failure due to vibration if not properly supported. The arc suppressor should be secured to a stationary support using a 2U-4497 Strap, to prevent any motion of the suppressor body. Additionally, the connectors on both ends of the suppressor group should likewise be secured.

A suitable bracket for supporting an arc suppressor is the 116-6100 Plate. The addition of a 9R-2926 Plate should permit mounting the 116-6100 Plate around obstacles, if the 116-6100 Plate can not be installed directly in an existing application. The sure seal connectors on the 3E-9169 or 105-8827 Arc Suppressor Group should be secured with two 9G-9150 Clips. This prevents movement of the connectors relative to the suppressor body. The Deutsch connectors on the 130-0956 or 130-8134 Arc Suppressor Groups should be secured with two 9U-2277 Clip Assemblies. The clips should be bolted through the slotted holes on the 116-6100 Plate. See the following figure, which illustrates the proper installation of an arc suppressor group.

The 106-8704 Arc Suppressor is now being used for new machine designs. The 106-8704 Arc Suppressor contains less mass than previous arc suppressors, and can be strapped directly to the mating wiring harness.
