"UniVert 2" inverter
5 Start-Up
5.1Installation
When installing the INV, the following regulations must be observed:
•The INV has been designed for use in a dry room, practically free of dust.
•It is imperative to observe the specifications concerning ambient temperature and site altitude (see chapter “Technical Data”).
•Severe dust accumulation or a chemically aggressive atmosphere are not permissible; the system must be especially protected against conductive, humid dust deposits and condensation.
•The INV functions with forced air cooling. The supply air temperature must not exceed 45°C. The power loss of an INV is below 340 W at rated load.
•The inverter must be installed in suitable module racks.
5.2Connection
Before connecting the unit to the DC supply, ensure that the voltage values given on the nameplate correspond to the supplied voltages. The load is connected using terminals X2 (L1, N) on the front of the unit. The DC supply is connected using terminals X1
The discharge current lies below 3.5 mA. Prior to
With earthed DC systems, only the pole of the INV DC connection that is not earthed needs protection. Observe correct polarity of the DC lines.
The load current must be checked before connecting the load; a permanent overload is not permissible and has a very negative impact on the reliability and the service life of the unit.
DIL switch (see chapter 3.9 or chapter 4.11) CAN bus (see chapter 3.8 or chapter 4.10) Remote signals (see chapter 3.10 or chapter 4.12)
5.3Connecting the Loads / DC / Mains
When all lines have been connected completely, proceed as follows:
Individual INV operation:
•Switch off the INV, switch on miniature
•Connect the DC supply (The INV has a softstart device that limits the charging current in the input capacitors to a value below the rated current of the unit.)
•Switch on the INV
•Connect the load
