SECTION 2: CIRCUIT REQUIREMENTS

Operation

Serious personal injury could occur if you connect the machine to power before com- pleting the setup process. DO NOT connect the machine to the power until instructed later in this manual.

Electrocution or fire could result if machine is not grounded and installed in compliance with electrical codes. Compliance MUST be verified by a qualified electrician!

NOTICE

The Model G0671/G0672/G0673 is prewired for 220V operation. If you plan to use your Model G0673 at 440V, you MUST have a qualified electrican perform the 440V con- version described on this page.

Power Supply Circuit Requirements

You MUST connect your machine to a grounded circuit that is rated for the amperage given below. Never replace a circuit breaker on an existing cir- cuit with one of higher amperage without consult- ing a qualified electrician to ensure compliance with wiring codes. If you are unsure about the wiring codes in your area or you plan to con- nect your machine to a shared circuit, consult a qualified electrician.

Power Connection Device

We recommend having an electrician hardwire the machine (using a metal conduit setup) directly to a locking disconnect switch (Figure 6), which is directly connected to the power source.

440V Conversion

The Model G0673 can be converted for 440V operation. This conversion job consists of discon- necting the dust collector from the power source, changing the magnetic switch, and rewiring the motor for 440V operation, as shown on Page 42.

The necessary magnetic switch for this procedure can be purchased by calling Grizzly Customer Service at (800) 523-4777 and ordering Model G8296 (3-Phase 440V 10HP Mag Switch).

All wiring changes must be inspected by a quali- fied electrician before the dust collector is con- nected to the power source. If, at any time during this procedure you need help, call Grizzly Tech Support at (570) 546-9663.
