Supplying Electric Power - Amada vm Series Operator's Manual

SUPPLYING ELECTRIC POWER

WARNING
NOTICE
Supply the machine with 3-phase, AC 200V, 50/60 Hz electric power with
voltage variations of 10% or less.
these power supply conditions as required.
The apparent power of the machine is 11 kVA. Install a shop circuit breaker
that suits this power.
Use a power cable of such a size and type as to suit the power supply
voltage, wiring length, and wiring method.
Supply electric power to the machine from a source different from those for
welding or other machines that produce electrical noise. Ground the
machine with an independent grounding conductor. If the power cable
conductors and grounding conductor are shared by this machine and a
noise-producing machine, this machine may be damaged. Additionally, the
machine may abruptly stop its operation or may operate improperly. These
conditions can lead to a serious accident.
Connect the power cable to the machine as described below.
1 Check that the shop circuit breaker switch is turned off.
2 Turn the POWER switch on the electrical enclosure to OFF.
Remove the three screws securing the door of the electrical
3
enclosure, turn the POWER switch to RESET (OPEN), and open
the door of the electrical enclosure.
4 Pull the power cable from the shop circuit breaker through the
power inlet into the electrical enclosure.
5 Connect the three power cable conductors to the power terminals
L1, L2 and L3 and the grounding conductor to the ground terminal
PE.
6 Check that the voltage of the power source to the machine is the
same as the voltage required for the transformers and motors as
shown on the label attached to the electrical enclosure.
If you must use a different source voltage, change the wiring
connections of the transformers and motors, and change the
thermal relay settings of the motors or replace the thermal relays.
If fuses are installed, replace them as well.
Have a qualified electrician make the
necessary electrical connections.
Before opening the door of the electrical
enclosure, be sure to turn off the shop
circuit breaker switch.
Ground the machine independently of
other equipment.
Prepare a transformer that suits
