WIRING CONSIDERATIONS

For bidirectional operation of the SHAFTach™,

proper phasing of the two output channels is

important. Phase A channel leads phase B

channel for clockwise rotation as viewed from

the end-cap (anti-drive) end of the generator.

Interconnecting cables specified in the wiring

diagrams are based on typical applications.

Refer to the system drawing for specific cable

requirements where applicable.

Physical properties of cable such as abrasion,

temperature, tensile strength, solvents, etc.,

are dictated by the specific application. Gen-

eral electrical requirements are: stranded cop-

per, 22 thru 16 gauge, braid or foil with drain

wire, 0.05 MF maximum total mutual or direct

capacitance, outer sheath insulator, 1,000 ft.

max.

ENVIRONMENTAL

CONSIDERATIONS

Special attention is to be given to conduit runs, interconnection

wiring and NEMA type enclosure mounting. In those applications

where ambient temperatures are controlled within 40°F and high

humidity/washdown are not present, position the flexible conduit

with a slight sag to prevent any condensation from entering the

SHAFTach via conduit.

In harsh environments, which include temperature extremes, high

humidity, equipment washdown or atmosphere contamination,

extra care is required for interconnection. Follow these steps to

reduce potential problems:

NOTE: 5' FLEXIBLE CONDUIT STANDARD

FOR ALL OUTPUT OPTIONS

Always mount connection points, conduit couplings, junc-

tion boxes, etc., lower than actual generator.

Venting of generator is beneficial. One method is to take

conduit run outside of hostile area where practical. (Applies to

conduit installations only.)

For washdown areas, shroud or otherwise cover the

SHAFTach to prevent direct water spray. Do not attach the shroud

directly to the generator.

Keep conduit outputs and axis of rotation horizontal.

Purging of SHAFTach should be reviewed with Avtron.
