A-4
ELECTROMAGNETIC COMPATIBILITY (EMC)
The EMC classification of the POWER WAVE
®
i400 is
Industrial, Scientific and Medical (ISM) group 2, class A. The
POWER WAVE
®
i400 is for industrial use only. (See prints
L10093-1, -2 Safety Pages in the front of Instruction Manual
for further details).
Locate the POWER WAVE
®
i400 away from radio controlled
machinery. The normal operation of the POWER WAVE
®
i400 may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or damage to
the equipment.
INPUT AND GROUNDING CONNECTIONS
MACHINE GROUNDING
The frame of the welder must be grounded. A ground termi-
nal marked with the symbol shown is located inside the
reconnect/input access door for this purpose. See your
local and national electrical codes for proper grounding
methods.
INPUT CONNECTIONS
ELECTRIC SHOCK can kill.
• Only a qualified electrician should
connect the input leads to the POWER
WAVE
®
. Connections should be made
in accordance with all local and
National Electrical Codes and the con-
nection diagram located on the inside
of the reconnect / input access door
of the machine. Failure to do so may
result in bodily injury or death.
-----------------------------------------------------------------------
Use a three-phase supply line. A 1.75 inch (45 mm) diame-
ter access hole for the input supply is located on the case
back. Connect L1, L2, L3 and ground according to the input
supply and ground connection decals located near the input
power terminal block (1TB) and ground block inside of the
rear input reconnect box.
I
nput Fuse and Supply Wire Considerations
Refer to Specification in Installation Section for recommend-
ed fuse, wire sizes and type of the copper wires. Fuse the
input circuit with the recommended super lag fuse or delay
type breakers (also called "inverse time" or "thermal/mag-
netic" circuit breakers).
Choose input and grounding wire size according to local or
national electrical codes. Using input wire sizes, fuses or
circuit breakers smaller than recommended may result in
"nuisance" shut-offs from welder inrush currents, even if the
machine is not being used at high currents.
Input Voltage Selection
(See Figure A.1
)
The POWER WAVE
®
i400 is shipped connected for the
highest input voltage listed on the rating plate. To move this
connection to a different input voltage, see the diagram
located on the inside of the reconnect access door, also
illustrated below. If the Auxiliary lead (indicated as
ʻ
A
ʼ
) is
placed in the wrong position, there are two possible results.
If the lead is placed in a position higher than the applied line
voltage, the welder may not come on at all. If the Auxiliary
lead is placed in a position lower than the applied line volt-
age, the welder will not come on, and the fuse located in the
reconnect area will open. If this occurs, turn off the input
voltage, properly connect the auxiliary lead, replace the
fuse, and try again.
Power Supply Connection for the Fanuc R30iA / R30iB
Controller
The POWER WAVE
®
i400 is equipped with a dedicated
robot power terminal block (4TB) specifically designed to
feed input power directly to the Fanuc R30iA / R30iB con-
troller through the power source rotary ON/OFF switch. The
K2677-2 Integration kit provides the proper cable and instal-
lations instructions to make this connection.
The POWER WAVE
®
i400 on/off switch is not intended
as a service disconnect for this equipment. Only a qual-
ified electrician should connect the input leads to the
POWER WAVE
®
. Connections should be made in accor-
dance with all local and national electrical codes and
the connection diagram located on the inside of the
reconnect access door of the machine. Failure to do so
may result in bodily injury or death.
Do not attempt to back feed input power though the
robot power terminal block (4TB) into the POWER
WAVE
®
i400. This is not its intended purpose and may
result in machine damage, bodily injury or death.
