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
1.
Always mount connection points, conduit couplings, junc-
tion boxes, etc., lower than actual generator.
2.
Venting of generator is beneficial. One method is to take
conduit run outside of hostile area where practical. (Applies to
conduit installations only.)
3.
For washdown areas, shroud or otherwise cover the
SHAFTach to prevent direct water spray. Do not attach the shroud
directly to the generator.
4.
Keep conduit outputs and axis of rotation horizontal.
5.
Purging of SHAFTach should be reviewed with Avtron.
