Figure 9. Install Handle, 20 Amp Cutter
POWER INSTALLATION
These cutters are designed to operate on a properly
grounded 230 or 208 volt, 60 Hertz, single phase,
alternating current (ac) power source fused at 50 amps.
Have a qualified electrician verify the actual voltage at
the receptacle into which the cutter will be plugged and
confirm that the receptacle is properly fused and
grounded.
IMPORTANT: Do not operate the cutters if the actual
power source voltage is less than 198 Vac or greater
than 240 Vac. Contact a qualified electrician if this
problem exists. Operating on inadequate or excessive
power will result in improper performance and/or
damage to the cutter.
CONVERT FROM 230 V TO 208 V
OPERATION
WARNING
ELECTRIC SHOCK CAN KILL!
To reduce risk of electric shock, make certain the
cutter is unplugged from the ac power source.
These cutters are factory set for 230 Vac operation for
actual receptacle voltages between 219 and 240 Vac. If
the actual receptacle voltage falls between 198 and 218
Vac, it will be necessary to convert the cutter to
208 Vac operation as identified in Table 4. Make the
conversion according to the following procedure steps.

CAUTION
IMPORTANT: Failure to set these cutters to
match the actual power source voltage (see
Table 1) will cause improper cutter
performance and can cause damage to your
cutter.
1. Remove the sheet metal access panel on the right
side (when facing the front, 50 amp only) of the
cutter or remove the cover (20 amp).
2. Locate the contactor inside the cutter (see Figure
10) and convert to 208 volt operation according to
the instruction decal on the back of the cutter.
3. Reinstall the sheet metal access panel.
CONNECT THE CUTTER TO POWER
SOURCE
Connect the cutter to the power source according to the
following instructions.
WARNING
ELECTRIC SHOCK CAN KILL!
WARNING
FIRE CAN KILL, INJURE, AND CAUSE
PROPERTY DAMAGE!
To reduce the risk of electric shock and fire, connect
only to properly grounded and fused outlets. NEVER
ALTER the ac power cord or power cord plug provided
on the cutter. NEVER ALTER an extension cord or
extension cord plugs.
Do not alter the ac power cord or power cord plug on
this cutter. If the ac power cord plug does not mate
with your existing receptacle, have an NEMA 6-50R
receptacle installed by a qualified electrician in
accordance with National and local electrical codes and
ordinances. Do not use any adapters between the ac
power cord plug and ac power source receptacle.
