INSTALLATION NOTES

Because of the many different types of service, feeder, and

distribution equipment, no specific wiring instructions can be

provided. It is recommended that only copper wire be used. In

all cases it is essential that while the load is connected to the

generator, there can be absolutely no feedback from the genera-

tor to the power line or the power line to the generator. When

properly installed, the normal A.T.S. Control and safety systems

will eliminate all paths for feedback.

To wire the automatic transfer switch into the existing wiring, first

determine which circuits will be on the emergency load circuit. If

the entire load is to be transferred, the transfer switch can be

wired in directly after the watt-hour meter and the service en-

trance, providing the service entrance ampere rating is within the

transfer switch’s rated capability.

If only specific circuits are to be powered under emergency power

failure conditions, an additional distribution panel designated

“emergency distribution panel” must be installed.

All selected emergency circuits are removed from main distribu-

tion panels and installed in the emergency distribution panel. The

A.T.S. is then installed between the main panel and the emer-

gency distribution panel. Suggested circuits: freezer, refrigerator,

furnace, emergency lights, sump pump, emergency outlet circuits,

etc. Total running load must not exceed generator rating.

CONNECTIONS

NOTICE - CLASS 1 WIRING METHODS ARE TO BE USED FOR

ALL FIELD WIRING CONNECTIONS TO TERMINALS OF A

CLASS 2 CIRCUIT

Note: This symbol always indicates ground where

shown.

All wiring must be completed in accordance with the Nation

Electric Code as well as any state or local codes.

You must pay particular attention to wire size requirement for the

amperage of service you are dealing with. Appendix "1" provides

you guidance on wire sizing based on both wire type and amper-

age. Wire amperage's have been derated for 40

C ambient

temperatures operation.

A - Neutral Lugs, These neutral lugs are isolated from ground

and provided for you to connect your neutral wire from the

transfer switch to the generator.

Refer to the neutral lugs installed in your connection box for wire

sizing and proper torques specifications. If you have additional

question on wiring sizing contact the WINPOWER Service

department at 507-357-6707.

B - Generator Circuit Breaker, This circuit breaker provides

overload protection for the generator. Your power feeds from the

transfer switch will connect to the bottom lugs on the circuit

breaker. The generator power feeds have already been wired

into the upper lugs.

Please refer to the circuit breaker installed on your unit for

breaker lug capacities and proper torque specifications.

To select the proper conductor size between the Generator and

the ATS, first look at the amperage rating of the circuit breaker

and then refer to Appendix "1" for guidance on wire sizing based

on both wire type and amperage. Wire amperages have been

derated for 40

C ambient temperatures operation.

For additional information on wire sizing refer to table 310-16 of

the National Electrical Code ANSI/NFPA 70.

C - Ground Lug, These ground lugs are bonded to ground and

are provided for you to connect your ground wire from the transfer

switch to. Refer to the ground lugs installed in your connection

box for wire sizing and proper torques specifications. If you have

additional question on wiring sizing contact the WINPOWER

Service department at 507-357-6707.

D - 120 VOLT GFCI CIRCUIT TERMINAL BLOCK - These

terminals are rated for 85 amps and will handle wire sizes #4

AWG to #18 AWG. They should be torqued to 16 in. lbs. This

circuit must be fed from a fused circuit in the distribution panel

and provides power for the blockheater and the battery charger.

G - This lug is provided on the neutral terminal block to allow you

to run a neutral to ground lead if you are using the generator in a

stand alone application. This would be an application where

there is not a distribution panel and no other ground to neutral

bond in the wiring system. If a grounding wire is attached here

remove the floating neutral label in the panel. This will not be

used when you are wiring a generator and transfer switch

into an existing power system.
