SAFETY NOTES
Disconnect power from hoist before removing end
covers.
7-1. Voltage Conversion
Standard single phase units are convertible from 115 to 230
volts and standard single speed three phase units are
convertible from 460 to 230 volts. Conversion to the alternate
voltage can be accomplished with the following procedure.
a. Be sure power is disconnected from hoist. Remove long
end cover.
b. Single Phase Hoists (With SINPAC' switch): Transfer leads
2. H2, H3, T2, S1, and T3 per the appropriate terminal block
schematic.
c. Three Phase Hoists: Transfer leads T4, T5, T6, T7, T8,T9,
H2, H3, S1, and S2 per the appropriate terminal block
schematic.
SECTION VII - WIRING
d. After converting voltage, check for proper phasing of three
phase units and check for proper limit switch operation.
7-2. Wiring Diagrams
The wiring diagrams for standard hoist models are reproduced
on the following pages. In addition, every hoist should have a
wiring diagram located inside the long end cover.
