Delta 11-985 instruction manual Power Connections, Extension Cords, Grounding Instructions

POWER CONNECTIONS

A separate 110-120 volt, grounded electrical circuit should be used for your drill press. This circuit should not be less than #12 wire and should be protected with a 20 amp fuse or circuit breaker. Before connecting the drill press to the power line, make sure the switch is in the "OFF" position.

If the power cord is worn, cut, or damaged in any way, have it replaced immediately by a certified electrician to avoid electrical shock or fire hazard.

extension cord, be sure to use one heavy enough to		0-6	120	50-100		16 AWG
carry the current to your drill press. An undersized cord		0-6	120	100-150		14 AWG
will cause a drop in line voltage resulting in a loss of

power and overheating. Fig. 18, shows the size cord to

Improper connection of the equipment-grounding conductor can result in 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. Use only 3-wire extension cords that have 3-prong grounding type plugs and 3-hole receptacles that accept the tool's plug, as shown in Fig. 19.

Repair or replace damaged or worn cord immediately.
