Powermatic PM1800 operating instructions Dust Collection, Electrical Connections

Dust Collection

The use of a dust collection system is strongly recommended for this band saw. It will help keep the shop clean, as well as reduce potential health hazards caused by inhalation of wood dust. The collector should have a capacity sufficient for this size machine – 400 CFM is recommended. Walter Meier has a line of dust collection systems available; see your dealer or visit our website listed on the back cover.

Connect the hoses of your dust collection system to the 4” dust ports at the rear of the band saw. Secure tightly with hose clamps (not provided). See Figure 18.

Electrical Connections

Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

Single Phase Connections

The single phase Band Saw is factory wired for 230 volts. It is not supplied with a plug. You may either install a UL/CSA-listed plug suitable for 230 volt operation, or “hard-wire” the Band Saw directly to a service panel.

It is recommended that the single phase Band Saw be connected to a grounded and dedicated, minimum 50 amp circuit with a 50 amp circuit breaker or time delay fuse. Local codes take precedence over recommendations.

Three Phase Connections

The three phase Band Saw is factory wired for 230 volts. It is not supplied with a plug. You may either install a UL/CSA-listed plug suitable for 230 volt operation, or “hard-wire” the Band Saw directly to a service panel.

The three phase Band Saw may be converted to 460V operation. The current contactor must be replaced with the 460V magnetic contactor (part no. PM2000-293C, purchased separately). In addition, re-connect the motor leads according to the diagrams inside the motor junction box. (Similar diagrams may be found at the back of this manual.)

It is recommended that the three phase Band Saw be connected to a grounded and dedicated, minimum 30 amp circuit with a 30 amp circuit breaker or time delay fuse. Local codes take precedence over recommendations.

Figure 18

If the single phase or three phase Band Saw is to be “hard-wired” to a service panel, make sure a disconnect is available for the operator. During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the Band Saw will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

Grounding Instructions

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipment- grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipment- grounding conductor.

If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Repair or replace a damaged or worn cord immediately.

Make sure the voltage of your power supply matches the specifications on the motor plate of the Band Saw.
