Identifying the Ground wire:
Caution: The machine may appear to operate with an incorrectly connected ground wire, but it will not
operate properly. Selecting the correct ground wire is important for proper machine operation and
personnel safety.
Ground wires on Longevity™ machines are usually one of the following colors:
The ground wire is a dark green with a yellow stripe. The wire may also be just SOLID GREEN.
Clean the ends of the wires to more easily distinguish the colors. The best and safest way to determine
which wire is ground is to measure the resistance between the machine chassis and the selected wire,
using an ohmmeter. Another method is to check the continuity between the chassis and the wire, using a
continuity meter. If the selected wire is ground, the connection between the chassis and the wire will
cause the meter to illuminate. If, for any reason, you cannot visually detect the ground wire or do not feel
comfortable with your selection, ask an electrician for help.
Identifying the hot wire:
For 220vac service, both the brown and blue wire will be positive wires. As you may know, 220vac
features two hot wires. If you are wiring to 220vac, your blue and brown wires are both hot. The
green with yellow or SOLID GREEN is the ground. Remember, any hot wire can be attached to
either hot leg on the plug.
Note: Hot Wires May also be WHITE and BLACK if a GREEN WIRE is one of the three
wires. Therefore, GREEN is ALWAYS GROUND.
