1.3 STRUCTURE
1.3.1 Power supply sources
1.3.1 Power supply sources
REV-302 may be powered by a standard 220V/50Hz AC circuit (terminals 7-8) or by a 24V DC source
(terminals 9-10). Only one power source can be connected at a time.
In order to provide for the standalone clock operation in case of power voltage loss and to backup the
programmed settings a 3V CR2032 lithium battery is utilized. The battery has 10 year life period.
If after an external power failure the time setting drops, the battery has to be replaced. To replace a dead
battery:
- make sure that REV-302 is disconnected from the AC power supply and the DC power supply (terminals
7-10, fig. 1.1);
- unscrew the mounting screws 9;
- remove the upper cover;
- remove the old battery;
- install a new CR2032, 3V battery into the holder block;
- re-install the upper cover and the screw position 9 screws back on;
- power the device via AC or DC power supply;
- set the correct time via settings menu.
- remove the upper cover;
- remove the old battery;

ATTENTION! The user may replace the clock battery on his/her own only in devices with expired
warranty period. Otherwise, damaging the seal will cancel the manufacturer’s warranty.
