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.

 Install the module only in areas with limited access to unskilled personnel.

 Before starting work, the electrical module must be disconnected from mains. Make sure

that the module is earthed.

 Do not touch connector pins as they can be charged with dangerous voltage up to 30

seconds after disconnection.

 Only spare parts approved by the manufacturer must be used.

1B. Electric Waste Disposal

Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment.

In the case of waste disposal of your discarded equipment we recommend to contact a waste management company.

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. The inverters are controlled and monitored by an internal microprocessor. Due to the outstanding switching principle the units have very low losses and therefore very compact dimensions, low weight and a very high power density. All main functional parameters are adjustable with front side operating keys and are indicated with digital displays. To increase the reliability the UNV-F inverter is designed to operate together with a static transfer switch of series UNB. The static transfer switch monitors the connected bypass mains and synchronizes the inverter output with mains frequency. In inverter priority mode the UNB transfers the load supply to bypass mains in case of inverter faults, high overload or battery low voltage. The transfer is nearly without voltage interruption (<4ms). The unit switches back to inverter operation automatically if the reason for the transfer is gone. In case of mains priority mode the inverter will take over the load if the mains voltage is not present, out of limits or heavy disturbed. The priority source is programmable at the UNB unit (see separate manual).

3.1 Mounting accessories

 Mounting set for 19’’ cabinet (not for UNV48-5.0F): Mat. code 880-MEC-MKT.01

 Mounting set for 19’’ cabinet (for UNV48-5.0F): Mat. code 880-MEC-MKT.02

The mounting set is necessary to fit the UNV module in a 19’’ compatible cabinet (see section 4.2 “commissioning”).

(Input/output fuse)

All operating elements are arranged at the front side of the module. The UNV-F, 2.5 and 3.3kVA are fitted with a combined input and output MCB which is used as ON/OFF switch, whereas the 5.0kVA version is fitted with a mechanical switch.

As shown with the front view the unit is equipped with seven LED indications:

 Switch symbol (Operation)  Vo (Output voltage ok)  Vi> (Input overvoltage)  Vi< (Input undervoltage)  Io> (Overload)  T> (Overtemperature)  Bell symbol (General alarm)

Two digital displays indicate the output voltage and output current values.

Detailed information concerning signalling and monitoring are described in the following sections.

The maximum allowed load for the relay contacts is:

 @ V= 110V / I< 0.45A

 @ V 60V

DC / I< 1ADC

*In parallel operation the contacts SYNC – GND and SYNC – SIG of each inverter have to be wired.

**In operation with an UNB it is necessary to interconnect the synchronization bus (contacts SYNC – GND, SYNC – SIG and SYNC – STAT) between the inverter(s) and the UNB.

***Potential free relay contact with safe electrical separation to the AC and DC side; in case of failure COM and NC are closed.
