1. Safety Instructions
Warning!
Because several components of operating electrical devices are charged by dangerous voltage, the
improper handling of electrical devices may be the cause of accidents involving electrocution, injury,
or material damages.
Operation and maintenance of electrical devices 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 device 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.
2. Waste Disposal Rules
All electric devices must be disposed of separate from domestic waste at collecting points that have
been set up by the government or municipal authority.
“Separate collection is the precondition to ensure specific treatment and recycling of WEEE and is
necessary to achieve the chosen level of protection of human health and the environment in the
Community.”
The above statement from EU directive 2002/96/EC applies to all electric devices installed within
EU countries.
In countries outside the EU, different rules may apply regarding waste disposal of electric devices.
For more information about waste disposal of your discarded equipment, contact your
ELTEK VALERE INDUSTRIAL partner.

3.5 Cooling/Air Flow Direction
The INV222 (INV215) and STS207 units are cooled with internal fans. The airflow is from the front to
rear side. The fans are monitored and speed controlled dependent on module temperature. To provide
sufficient air flow, a minimum space (see item “A” in figure 3) of 50 mm is required between the back-
plane of the rack and the rear cabinet wall as well as an unobstructed supply of air to the front of the
modules.

4. Handling
4.1 Storage
AC racks must be stored in a dry, dust free environment with a storage temperature in accordance
with the specific technical data (see section 6).
4.2 Commissioning
Carefully unpack the unit and integrate it in your power supply cabinet with 4 screws M6 (1) at
the front side.
Figure 4) - Front view of the empty rack
4.2.1 Assembling
Assemble the modules into the slots of the sub rack.
Fill the rack beginning with the left slot (slot 1 to 3 for INV222/INV215, slot 4 for STS207)
Fix the modules with the captive screws.
Not used slots must be covered with cover plates (see section “Optional Equipment”).

4.2.2 Communication Interface/Termination
The AC rack is equipped with a serial data interface in accordance with the Controller Area Network
(CAN) specification.
Several racks and/or modules in a system can be controlled and monitored through the CAN-Bus by a
central DC controller unit UPC3.
Two CAN-Bus connectors (X21= CAN 1; X22= CAN 2) are located at the rear of the sub rack
(see figure 5).
4.2.3 CAN-BUS Addresses
All modules within a system must have a specific CAN-BUS address for a clear identification through
the central controller unit.
The CAN-BUS addresses of the installed inverters are automatically designated by the AC rack.
4.2.4 Termination
The CAN-Bus must be terminated at both ends.
If no other rack and/or module is connected (CAN 2 not used), the CAN-Bus termination resis-
tor must be activated with the plugged jumper at the rear of the backplane of the AC rack (see
figure 6).
If CAN 2 is connected, the CAN-Bus termination resistor must be deactivated (the jumper must
be removed).
Not more than two termination resistors should be activated on one bus and these should be
located at both ends of the bus.
ATTENTION: Missing terminations or too many terminations within the system can disturb the CAN-Bus
communication.

5. Maintenance
In general, the system is maintenance-free.
A yearly inspection with following checks is recommended:
Correct fan operation (modules)
Mechanical inspection
Removal of dust and dirt
Check for internal dust or humidity
Attention! Dust combined with moisture or water may influence or destroy the internal electronic
circuits.
Dust inside the unit can be blown out with dry compressed air.
The interval between the checks depends on the ambient conditions of the installed system.
To exchange defective fans in the inverter modules, an additional instruction manual is available on
request.
