WM100 Typical Wiring

Should the time delay feature on start up not be required, power should be applied

continuously from a separate source. Typically this would be desirable for automatic

upstream start up of conveying devices after down stream drive has reached its operation

speed.

Note

1. Interlocks and safety pull switches are not shown.

2. If 'START' is initiated by programmable logic controller, closure time may be of insufficient

duration to allow WM100 contact to latch. In such a case, program a timer contact into

circuit.

3. CSA requires a 3 A or less fuse to protect contacts. For 240 V AC, protect contacts with a

1500 VA transformer as well.
