DC/AC Inverter UNV-F User Manual Page 5 (28) 1A. Safety Instructions Warning! Because several components of operating electrical modules are charged by dangerous voltage, the improper handling of electrical modules may be the cause of accidents involving electrocution, injury, or material damages. Operation and maintenance of electrical modules must be performed by qualified skilled personnel such as electricians in accordance with EN 50110-1 or IEC 60950.
DC/AC Inverter UNV-F User Manual Page 6 (28) 2. General Information Inverters of the series UNV-F convert input side DC voltage to a stable sinusoidal output voltage. The inverters are available for delivery with an output power of 2.5, 3.3 and 5.0 kVA per module. Several units can be switched in parallel operation to increase the system output power. The UNV-F is a hot-pluggable module with rear side connectors. Only the communication wire (CAN-Bus) is connected at the front.

DC/AC Inverter UNV-F User Manual Page 12 (28) 3.5 Communication Interface The inverter UNV-F is equipped with a serial data interface according to CAN (= Controller Area Network) – specification. Via CAN-Bus, several devices in a system or parallel connection can be controlled and monitored by a central unit which is integrated into the static transfer switch unit UNB.
DC/AC Inverter UNV-F User Manual Page 13 (28) For the electrical connection of DC input and AC output the backside panel connector is to be used. The DC input is protected against wrong polarity (unit does not switch on). The UNV-F with output power of 2.5 and 3.3kVA are fitted with an output side MCB fusing at the front panel combined with an input side MCB, whereas the 5kVA version is fitted with a mechanical switch. That means that the 5kVA version must be fused with external fuses.
