ElECtrIC SHoCK CAN KIll! Precaution-
ary measures should be taken to provide
maximum protection against electrical
shock. Be sure that all power is off by
opening the line (wall) disconnect switch
and by unplugging the power cord to the
unit when connections are made inside of
the power source.
CAutIoN
Be sure that the power source is properly
configured for your input power supply.
Do Not connect a power source configured
for 230 V to a 460 V input power supply.
Damage to the machine may occur.
400V CE Mains Supply requirements:
High power equipment may, due to the primary current drawn from the mains supply, influence the pow-
er quality of the grid. Therefore connection restrictions or requirements regarding the maximum permis-
sible mains impedance or the required minimum supply capacity at the interface point to the public grid
may apply for some types of equipment (see technical data). In this case it is the responsibility of the
installer or user of the equipment to ensure, by consultation with the distribution network operator if
necessary, that the equipment may be connected.

A line (wall) disconnect switch with fuses or circuit breakers should be provided at the
main power panel (see Fig. 3-1 and Table 3-1 for fuse sizes). The input power cable of
the console may be connected directly to the disconnect switch or you may purchase
a proper plug and receptacle from a local electrical supplier. If using plug/receptacle
combination, see Table 3-1 for recommended input conductors for connecting receptacle
to line disconnect switch.
The POWERCUT 650 power source with 230 vac, 1 / 3 -phase input capability is factory
set for 230 vac input.
NOTE: PC-650 input cable differences
The colors of input phases of the CE models differ from those of the "non CE" models.
Below is a table comparing the two:
400 & 460-Volt CE
For the 400 and 460-Volt units, it isn't important which leg is connected to L1, L2 and
L3, when 3-Phase input is used, however if inputting 1 phase power, L2 will be the un-
used leg. The T2 must have power to operate and it is connected across L1 and L3.
208/230-Volt models
**for SINglE-PHASE CoNNECtIoN of 230-Volt CE MoDElS:**
If single-phase connection is desired, connect the BlACK leg to "l3" and the
BroWN leg to "l1" with the grEY (l2) leg disconnected, lugged, and taped back.
, L2 will be the un-used leg. The T2 must have power to operate and it is connected
across L1 and L3.
