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.
Following parameters of a specific inverter unit can be controlled or monitored:
Remote ON/OFF
Inverter status (OK/failure)
Input voltage (measurement value)
Input current (measurement value)
The CAN-Bus connectors are located at the front panel. The wiring to the central unit should be as short as
possible. The cable length must not exceed 30m.
4. Handling
4.1 Storage
The devices must be stored in a dry, dust free environment with a storage temperature according to specific
data (please see section 7).
4.2 Commissioning
Note:
Before commissioning the module, make sure that the input voltage corresponds to the input voltage
range of the unit as specified on the type plate.
If the inverter is to be mounted in a 19’’ compatible cabinet, a mounting set is necessary (see picture below).
After unpacking the unit put it upon the rails and slide in the unit carefully over the rails until the module
connector gets in touch with the backplane connector. Increase the pressure a little bit until the unit fits in
completely. Please avoid too much pressure. If the unit does not fit in please start again with the complete
slide-in process.
Mount the unit with 4 screws (M4x12).
