Electrical Connections, Dust Outlet and Cord Plate

Dust Outlet and Cord Plate

Refer to Figure 12:

1.Install the dust outlet using the four M6 x 12 pan head flanged screws (FF).

2.Single Phase model: Feed the electrical plug through the hole in the stand, and slide the cord plate through also. Secure the cord plate to the stand using the two M5x12 pan head screws (GG) as shown.

Switch (Single Phase Model)

Refer to Figure 13:

1. Place the push button switch into the rectangular opening from inside the stand.

Figure 12

2. Secure the switch to the outside of the stand, using two M4x8 pan head screws (HH), two M4 lock washers (JJ) and two M4 flat washers (KK).

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 31A Sander is equipped with either a single phase 115/230 volt motor (pre-wired 115V); or a three phase 230/460 volt motor (pre-wired 230V).

The three phase sander is not equipped with a plug. You may either install a UL/CSA listed plug suitable for 230 or 460 volt operation, or “hard- wire” the sander directly to a service panel. The installer shall follow local regulations and National Electrical Code, ANSI/NFPA 70 installation requirements. If the Sander is to be hard-wired to a 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 Sander will be connected.

If connected to a circuit protected by fuses, use time delay fuse marked “D”.

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

Figure 13

(single phase model)

It is recommended that the single phase sander be connected to a dedicated 30 amp circuit (for 115V) or 20 amp circuit (for 230V) with circuit breaker or time-delay fuse marked “D”.

It is recommended that the three phase sander be connected to a dedicated 20 amp circuit (for 230V) or 10 amp circuit (for 460V) with circuit breaker or time-delay fuse marked “D”.

NOTE: Local codes take precedence over recommendations.

Converting from 115 Volt to 230 Volt (Single Phase Only)

To convert from 115V to 230V (1 phase model), consult the diagrams inside the cover of the motor junction box, to determine how to switch the motor leads. A similar diagram is also found at the back of this manual.

The 115V attachment plug supplied with the sander must be replaced with a UL/CSA listed plug suitable for 230V operation. Contact your local authorized Powermatic service center or qualified electrician for proper procedures to install the plug. The sander must comply with all local and national codes after the 230 volt plug is installed.
