Installation | Checking Whether the Power Is On or Off
Inrush current
When the POWER switch is turned on, an inrush current flows. Check that sufficient current capacity is
available in the AC power line or the switchboard, particularly if you are using multiple units and turning on
their POWER switches simultaneously. For the inrush current of each model, see “Specifications”
.
Turning off the POWER switch
Turn the POWER switch off ( ).
This product saves the panel settings (except the output on/off setting) that were in use immediately
before the POWER switch was turned off.
You can use the CONFIG settings (CF01) to select the output state of the product when the POWER
switch is turned on
If the POWER switch is turned off immediately after the settings have been changed, the last settings may
not be stored.
CAUTION
If you want to turn the POWER switch back on, wait at least 10 seconds after the panel dis-
play turns off. Repeatedly turning the POWER switch on and off at short intervals can cause
damage to the internal circuit. Furthermore, this will shorten the service life of the POWER
switch and the internal input fuse.
In some cases, the keys may become uncontrollable or a malfunction may occur in the alarm
indicators or the like. Turn the POWER switch off once and then back on.
