ELECTRICAL

The machine must be properly set up before it is safe to operate. DO NOT connect this machine to the power source until instructed to do so in the "Power Connection" portion of this manual.

Phase Operation

The Model W1773 is prewired for 220V 3-phase operation, but may be rewired for 440V 3-phase operation (see Page 13).

This machine must be hardwired to a locking shutoff switch by a qualified electrician. Hardwiring involves a permanent installation with conduit runs that can only be accomplished safely by a qualified electrician. As always, observe all applicable electrical codes when connecting this machine to power.

This machine must be grounded! Verify the ground before connecting this machine to the power source.

Phase Converter

The power from the manufactured power leg (wild wire) of a phase converter fluctuates, which may damage elec- trical components if connected to the wrong incoming power terminal. If you must use a phase converter for 3-phase power, only connect the "wild wire" to the L1 terminal. The wire from the L1 terminal can handle some fluctuation because it goes directly to the motor. The power going to the L2 and L3 terminals connects to the controls and must be consistent to prevent damage.

Attempting to connect this machine to the power source without a qualified electrician greatly increases the risk of electrocution, fire, or machine damage.
