Power On Information DisplayInrush CurrentWhen the POWER switch is turned on, an inrush current of up to 70 A can momentarily flowinto the rear AC input of the programmable power supply. Check that sufficient current capacityis available in the AC power line or the switchboard, particularly if you are using multiple RMXprogrammable power supplies and turning on their POWER switches simultaneously.Turning the POWER Switch OffFlip the POWER switch to the side to turn RMX programmable power supplies off. The RMXprogrammable power supplies save the panel settings (except the output on/off setting) that werein use immediately before the POWER switch was turned off.You can use CONFIG settings CF02 to select how the RMX programmable power supply startswhen the POWER switch is turned on. Refer to Chapter 2, CF02 Power-on Status Parameter,for more information about this setting.If the POWER switch is turned off immediately after the settings have been changed, the lastsettings may not be stored.Caution After you turn the POWER switch off, wait at least 10 seconds after thepanel display turns off before you turn the POWER switch back on. Repeatedlyturning the POWER switch on and off at short intervals can cause damage to theinrush current limiter. Furthermore, this will shorten the service life of the POWERswitch and the internal input fuse.
