CHAPTER 3 Main Unit Power-on/off
4
For a unit using software-based automatic power control, do not set the MODE
switch on the operator panel to UNLOCK or LOCK. If a main line switch in the
power distribution box is switched off and on while the MODE switch is set to
UNLOCK or LOCK, the unit may be powered on automatically as soon as the
main line switch is switched on. To avoid this, set the MODE switch to
MAINTENANCE.

A dual power feed configuration requires a dual power feed option. If the main
unit without the option mounted is connected to different power supply sources
using multiple power cables, it is not a supported dual power feed configuration.
This option is mounted in the main unit before shipment. Include this option
when placing an order for a main unit. If this option is required after the main
unit has been installed in the field, consult your sales representative.
