Inrush Current
When the POWER switch is turned on, an inrush current of up to 70 A can momentarily flow
into the rear AC input of the programmable power supply. Check that sufficient current capacity
is available in the AC power line or the switchboard, particularly if you are using multiple RMX
programmable power supplies and turning on their POWER switches simultaneously.
Turning the POWER Switch Off
Flip the POWER switch to the side to turn RMX programmable power supplies off. The RMX
programmable power supplies save the panel settings (except the output on/off setting) that were
in use immediately before the POWER switch was turned off.
You can use CONFIG settings CF02 to select how the RMX programmable power supply starts
when 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 last
settings may not be stored.
Caution
After you turn the POWER switch off, wait at least 10 seconds after the
panel display turns off before you turn the POWER switch back on. Repeatedly
turning the POWER switch on and off at short intervals can cause damage to the
inrush current limiter. Furthermore, this will shorten the service life of the POWER
switch and the internal input fuse.
