power supply

Cold start function

• The UPS can be switched on without connection to the mains using the cold start function. In

order to switch on the UPS, press and hold down the button k within 4 sec. The buzzer beeps four

times, the output voltage indicator a displays the ﬁgure “220” and the power will be supplied to

devices-consumers.

Note. It is not recommended to use the cold start function when the connected load is large.

Sound alarm and protection

• At the instant the UPS starts to use power from batteries (when there is power failure), it beeps

4 times. Then the UPS beeps every 30 seconds, when it operates from batteries. This function can
