Qualifications and Requirements
XPR300 Instruction Manual 809480 45
Input power requirements for CE units
The XPR cutting system is intended for use only in sites that have a service current capacity that is
greater than (or equal to) 100 A per phase and supplied from a distribution network that has a
nominal voltage of 400/230 V. The installer or user is responsible for verifying that the service
current capacity for the installation site satisfies this requirement.
Remote on-off switch
You must supply the remote on-off switch (or switches) for your cutting system.
A remote on-off switch lets you supply electric power to or remove electric power from the gas
connect console, torch connect console, and some parts of the plasma power supply from a
location that is remote from the main power source. A convenient location for a remote on-off switch
is near the CNC.
For information about how to do this, refer to How to install a remote
on-off switch on page 196.
WARNING
ELECTRIC SHOCK CAN KILL
The plasma power supply contains dangerous electric voltages that can seriously injure or
kill you.
Even if the plasma power supply is turned OFF, you can still get a serious electric
shock if the plasma power supply remains connected to an electric power source. When
the remote on-off switch is in the OFF position, electric power remains active to the
following components in the system:
• Control board
• Control transformer input and output
• 48 V power supply
• 24 V power supply
• 120 VAC and 220 VAC on the power distribution board
• Input side of the contactors
• Input side of the pump relay
• Power-indicator LED on the front of the plasma power supply
Use extreme caution if you do diagnosis or maintenance tasks when the plasma power
supply remains connected to an electric power source and the outer cover or panels are
removed. All work that requires removal of the plasma power supply outer cover or panels
must be done by a qualified technician.
