1.1General

Congratulations on your choice of Silcon DP300E UPS (Uninterruptible Power Supply). This UPS has been designed and produced for reliable and troublefree long-term use. For you it means that once installed and commissioned, you can forget it. However, you should arrange for preventive maintenance as described in section 8.0 of this manual.

1.2The display unit

The display unit – placed on the front of the Silcon DP300E UPS – is the link between user and UPS. It consists of a display, an alarm LED, and a keyboard.

The display is used for showing parameters, measured values, and alarm messages. A backlight is activated in case of an alarm or if one of the keys are pressed. No activity or no alarm for 5 minutes will automatically switch of the light.

By pressing and simultaneously you increase the contrast, and by

pressing and simultaneously you decrease the contrast.

The alarm LED is linked with an acoustic signal as an indicator for unusual operating situations. The light changes from green to red in case of alarm. The keyboard is used for programming of operating parameters and for calling read- outs of parameters/alarm messages.

NOTE:

The display accuracy is ±1-2%,

±1 digit.
