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 per-
sonnel 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 man-
agement company.

2. General Information
The static transfer switch STS207 is designed for a nominal switching capacity of 7kVA and is used for
nearly interruption free switching (<4 ms) between two AC sources (usually inverter and substitute-
mains supply). It is intended for the operation in combination with inverters of series INV215/222. Con-
sequently AC consumer loads can be driven nearly without interruption if one of the two power sources
fails.
The STS207 is a hot plug-in module with rear side connectors and is designed to be mounted in an
assembly set sub rack (see section 3.2).
The operation and indication elements as well as an Ethernet and CAN-Bus connector are user-friendly
integrated in the front plate of the unit.

2.2 Operating modes
The static transfer switch STS is designed for the operating modes “inverter priority” and
“mains priority” alternatively. The consumer load is energized by the priority source as long as that
source works faultlessly.
REMARK: The unit's default setting is "Inverter priority".
The priority source is programmable using "service menu 2" (only available on request for qualified and
skilled service personnel).
2.2.1 "Inverter priority" (default setting)
At the operating mode “inverter priority” the load is switched on inverters during normal operation.
Source “Mains” only is required to energize the consumer load if source “Inverter” fails or is overloaded
(i. e. distortions by short circuit behaviour or overload).
2.2.2 "Mains priority"
At the operating mode “mains priority” AC mains works as priority source and the inverter
(as “substitute mains”) as source 2. The STS only switches to inverter(s) when mains failes.

3.5 Cooling/Air flow direction
The unit is cooled by an internal fan. The airflow is from the front to rear side. The fan is monitored and
speed controlled dependent on module temperature. To provide sufficient air flow, a minimum space
(see item “A” in figure 7) of 50 mm is required between the unit and the rear cabinet wall as well as an
unobstructed supply of air to the front of the module.
Figure 7. Module air flow
3.6 Communication interfaces
3.6.1 CAN-Bus
The STS207 is equipped with a serial data interface in accordance with the Controller Area Network
(CAN) specification. The CAN-Bus connection is integrated in the rear side connector and an additional
one is located at the front panel.
The communication of the STS207 with the connected inverters and a possibly implemented UPC3 DC
controller unit takes place via CAN-Bus.
The following information is available via CAN:
Status information of the STS207:
Availability of the connected inverters
Availability of the substitute mains

4. Handling
4.1 Storage
The STS must be stored in a dry, dust free environment with a storage temperature according to
specific data (see section 8).
4.2 Commissioning
Note: Before commissioning the module, make sure that the battery voltage for redundant circuitry
supply of the STS corresponds to the specification as specified on the type plate.
1. Carefully unpack the unit
2. Put the unit into the provided slot to the right of the sub rack.
3. Carefully slide in the unit until the module connector touched the backplane connector.
4. Increase the force until the unit fits in completely. Avoid using too much force. If the unit does not
fit in, begin again at step 2.
5. Secure the module using the captive screw provided with the module.
Caution: After switching off the module the internal capacitors are still fully charged. Do not touch
connector pins as they can still be charged with dangerous voltage after disconnection.
4.3 Operation
The operation of the unit takes place with keys located on the front side of the unit.
All main functional parameters and measured values are displayed on the front side LCD panel (text
indicator) as well as with LED indicators. The different functions are described in the following sections.

4.3.3 LC-Display: Indication of measured values and alarm messages
In its initial state, the display shows the measured voltage of the input sources (AC output voltage of
inverter, mains voltage) and the STS output current.
Pushing the keys and changes between different display topics.
Figure 9. LC-Display: Indication of measured values
The display [1] shows the initial state (basic display). The plain text of the basic display becomes visible
after a successful start-up procedure. As shown in figure 9., you can select the displays [1], [2], [3] and
[4] by pressing the keys or :
If no inverter is registered, display [4] is not available.
If exactly one inverter is registered, display [4] is visible without inverter number.
If more than one inverter is registered, it is possible to call the parameters (input current,
output current and status) of all connected inverters in succession by pressing “ENT”.
The inverter number is shown in the first line of the display. Press “ESC” to go one step back.
The display automatically will revert to display [1] if no key is pressed for a period of more than
30 seconds.
Display [5] “Alarm messages” indicates the current alarm status. It can be selected from display [1], [2]
and [3] by pressing “ESC”.
By pressing the keys or you can scroll through the list of alarm messages if more than three
entries are present there. The display “Alarm messages” can be quit by pressing “ESC” again.
Basically (factory setting) all individual failures according to “List of the selectable individual alarm
messages“, (see section 5.1) are switched “active” and therefore they are visible on the display in case
of failure. The alarm messages which shall not be visible on the display in case of failure are to be
switched “inactive” in the customer menu (see the diagram “customer menu”).
