Connecting 208 / 230 / 240 VAC Power
Installation must meet all National and Local
Codes. This installation must be
electrically con-
nected
by a Suitably Trained and Qualified Trades-
person.
DO NOT TOUCH
any
live electrical parts or conductors.
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is
on.
DO NOT WORK ALONE! The Input Power Sup-
ply circuit and Power Source internal circuits
are also live when power is on.
NOTE
6:
These products configures the Power Source to the
operating parameters for 120 / 208 / 230 / 240 VAC.
Electrical Input Requirements
Operate the Power Source from a single-phase, 50/60 Hz,
AC Power Supply
available on SITE
. The
Input Supply Volt-
age
must match one of the electrical input voltages shown in
this manual.
Refer to Figure 2 and
Table 2
for connection, maximum
Input Supply Voltage and Fuse Size.
NOTE 7
:
DO NOT
connect an Input Power Cord (WHITE or
BLACK) cable to the ground terminal.
NOTE 8
:
DO NOT
connect an Input Power Cord ground
(GREEN) cable to the Input Primary Supply terminal.
