Nteunting Guidelines

Thesystem circuitry is enclosed in a NEMAType3R enclosure suitable for indoor_outdoor use.Guidelinesfor

mounting the enclosure include:

° Install enclosure ona firm, sturdy supporting structure. ° The enclosure must be installed with minimum

NEMA3R hardwarefor conduit connections.

, To prevent switch contact distortion, leveland plumb

the enclosure.This can be done by placing washers betweenthe enclosure and the mounting surface.

, NEVERinstall the switch whereany corrosive

substance might drip onto the enclosure.

, Protect the switch at all times against excessive

moisture, dust, dirt, lint, construction grit and corrosive vapors.

Typical automatic transfer switch installations are depicted below, it is best if the transfer switch is mounted near

the utility meter,either insideor outside. Discuss layout suggestions/changes with the owner beforebeginning the system installation process.

Maintenance

Thetransfer switch is designed to be maintenancefree under normal usage. However,inspection and maintenancechecks should be made on aregular basis. Maintenancewill consist mainly of keepingthe transfer switch clean.

Visual inspections should be done at least once amonth. Accessto transfer switch must not be obstructed. Keep 3 feet (92 cm) clearancearound transfer switch. Check

for an accumulation of dirt, moisture and/or corrosion on and around the enclosure, loose parts/hardware,

cracks and/or discoloration to insulation, and damagedor discolored components.

Exercisethe transfer switch at leastonce ever},three months as described in Testing the Automatic Transfer Switch unless a power outage occurs and homegenerator system has gone through an automatic sequence.Allow generatorto run for at

least 30 minutes. Contact a licensed electrical professional to inspect and clean

the inside of the enclosure and other components of your home generator systemat least once a year.

When Calling for Assistance

You must have the Model Number andSerial Numberfrom the unit ID label at hand if it is necessaryto contact alocal

servicecenter regarding service or repair of this unit. Obtain this information from the unit ID labellocated on or inside the

enclosure. To contact Briggs & Stratton call800-743-4115, between
