Powermatic PM1900TX manual Electrical Connections, Operating the Machine, Extension Cords

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.

The PM1900TX is equipped with either a single phase, 230 volt only motor; or a three phase, 230/460V motor (pre-wired 230V). Keep in mind that a circuit being used by other machines (tools, lights, heaters, etc.) at the same time will add to the electrical load. Thus, it is recommended that the single phase machine be connected to a dedicated 40 amp circuit, with a 40 amp circuit breaker or fuse. It is recommended that the three phase machine be connected to a dedicated 20 amp circuit with a 20 amp circuit breaker or fuse. Local codes take precedence over recommendations.

The three phase dust collector can be re-wired for 460V operation as follows:

To convert from 230 to 460 volt operation:

1.Disconnect from power source; unplug!

2.Connect the motor leads as shown in the diagram inside the motor junction box; this diagram is also shown on page 20 of this manual.

3.Replace the plug on the power cord with an appropriate UL/CSA listed 460V plug.

4.When finished wiring, re-install junction box cover.

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.

The hose or ductwork you use to connect the tool to the dust collector must also be grounded.

Make sure the voltage of your power supply matches the specifications on the motor plate of the dust collector.

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.

Extension Cords

If an extension cord is needed, make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 11 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

*based on limiting the line voltage drop to 5V at 150% of the rated amperes.

NR: Not Recommended.

Operating the Machine

3 Phase models: Connect the dust collector to the power source, and use the industrial-style push-button switch to operate the machine.

1 Phase models: If power is flowing, a green indicator will light on the face of the control panel. To operate the machine, use the buttons on the control panel, or use the provided remote control. To start the dust collector, press the ON button. If the remote control is used, aim it at the control panel. The machine will remain running until the OFF button is pressed. The digital readout will always display 00 while running.

The remote control operates on two AAA batteries. These will need replacing periodically.
