1 Safety notes
The inverter is an electronic device which operates at dangerous
voltage and current levels.
For this reason, the following instructions must be followed at all times!
1. The inverter should be installed, operated, repaired and maintained in
accordance with the instructions in this document.
2. Only fully trained and qualified personnel should have access to the
system. Only qualified and authorized personnel should be able to install
the units.
3. Even when the inverter is switched off, some of its interior components
remain live as long as it is connected to the commercial AC bypass supply
or the battery.
4. Capacitors may be charged even when the unit is disconnected. These
must be correctly discharged by a qualified electrician before the
connections or terminals are touched.
5. When working with the unit, use properly insulated tools at all times
which are suitable for the levels of voltage concerned.
6. All persons working with the unit must be familiar with the first-aid
measures to be adopted in cases of accidents involving electricity.
7. Always observe the regulations of the local operating company as well as
other safety regulations.
Attention!
The inverter may be operated only on 120 VAC (L1, N, G)
systems.
The neutral conductor of the inverter is connected internally to the
protective wire. ( )
Switch-over from inverter to commercial AC bypass or from
commercial AC bypass to inverter always takes place with both
the L1 and N poles!

2 General
The inverters in the product line TEBEVERT with an integrated switch-over
device can be utilized for a wide range of applications in the field of
telecommunications and other applications.
The output power of the inverter is either 500VA with 24VDC input models or
1000VA with 48VDC input models.
The inverters utilize Digital Signal Processor (DSP) technology, programmed with
the appropriate algorithms to carry out control and monitoring of the inverter.
Attention!
These inverters are not designed for parallel operation!

4 Assembly and commissioning
Attention!
The safety instructions must be observed at all times during
assembly, installation and commissioning!
After installation, connecting and commissioning the inverter is ready for
operation without restriction. No additional settings and readjustments are
necessary during operation under all operating conditions.
The inverter is designed for operation in closed and dry environment. The
maximum permissible ambient temperature is +40°C. without de-rating. The
inverter is designed to operate in a controlled environment. Attention must be paid
that the inverter is not exposed to aggressive airborne substances and that the
passage of cooling air is not hampered.
4.1 Device settings
Attention!
No adjustments are necessary for normal operation of these units.
4.2 Connecting the inverter
Attention!
The power-supply circuits (Commercial AC bypass input cable
and DC supply cables) must be provided with a disconnecting
device. The disconnecting devices should be readily accessible in
the vicinity of the inverter.
If a battery is connected, then the instructions concerning the
installation and maintenance given by the manufacturer of the
battery must be observed.
Before connecting the inverter, make sure that none of the
connections are live!
