C. Operation Instructions
(A) Selection of Power Supply Mode
To meet the requirements of different power supply voltage in different countries, all devices in
PC-LINK
system have three types of working voltage:
①
AC220-230V working voltage;
②
AC110-115V working voltage
;
③
DC24V working voltage, which
is used as the backup power supply in the system, i.e. in case of AC220V or AC110V is not available,
the device can operate normally under the DC24V power supply. The DC24V power supply is supplied
by PC1022E (emergency power supply device for PA system).
Use voltage selector on the back panel (shown in the following figure) to select working voltage.
Selection of AC110V Selection of AC220V
1)
When the selector is turned to the right till “115” appears, the working voltage of the device is set
to AC110V-115V.
2)
When the selector is turned to the left till “230” appears, the working voltage of the device is set to
AC220V-230V.
3)
DC24V can be used directly if neither of the above two types of power is available.
