6.17 Controls
The two-speed hoists are available for 208, 230, 460, 575 Volt - three-phase – 60 hertz power supplies. The
controls of the two-speed hoists are NOT re-connectable because the hoist motors are voltage specific.
Note: The controls of the motorized trolley drive are not voltage re-connectable. Consult the motorized
trolley manual if a voltage changeover is required.
Control Circuit Fuses
The PC board control on the hoist includes a fuse (F100) for control circuit protection.
