2 Safety
DANGER
Lethal voltages are still present in the connections and cables of the device even after the device
has been switched off and disconnected!
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched.
üOnly appropriately qualified and authorised electricians are permitted to open and uninstall the device.
üComply with all safety regulations and current technical connection specifications of the responsible power
supply company.
1. Switch off the grid voltage by turning off the external circuit breakers.
2. Secure the device against reconnection.
The electrician is responsible for observing all existing standards and regulations. The following applies:
– Keep unauthorised persons away from the device and/or system.
– Ensure operational safety by providing proper grounding, conductor dimensioning and appropriate protection against
short circuiting.
– Observe all safety instructions on the product and in these operating instructions.
– Switch off all voltage sources and secure them against being inadvertently switched back on before performing visual
inspections and maintenance.
– When taking measurements on the live device:
– Do not touch the electrical connections
– Remove all jewellery from wrists and fingers
– Ensure that the testing equipment is in safe operating condition.
– Modifications to the surroundings of the device must comply with the applicable national and local standards.
2.1 Proper use
The RPO device is designed exclusively for the reactive power compensation. During this period, the device is
activated by a control system.
The device is built using state-of-the-art technology and in accordance with the recognized safety rules. Never-
theless, improper use may cause lethal hazards for the operator or third parties, or may result in damage to the
product and other property.
The device is intended for indoor and outdoor applications and may only be used in countries for which it has
been approved or for which it has been released by KACO new energy and the grid operator. 1
Operate the device only with a permanent connection to the public power grid. The country and grid type se-
lection must be commensurate with the respective location and grid type.
The requirements of the grid operator must be met for grid connection to take place. The permission of the rel-
evant authorities may also be required in order to secure authorisation to connection to the grid.
The name plate must be permanently attached to the product and must be in legible condition.
NOTE:In addition to the parametrised preset data, it is also possible to apply a static setting.
Any other or additional use is not considered proper or intended use and can lead to an annulment of the
product guarantee. This includes:
– Use of a distribution system that is not described (grid type)
– Mobile use
– Use in rooms where there is a risk of explosion
– Use in direct sunlight, rain or a storm or other harsh environmental conditions
– Outdoor use in environmental conditions that exceed the limits stated in the technical specifications > [See
section4.3}Page13].

2.3 Functional restrictions
Note the following device-specific restrictions:
– It is not possible to connect PV modules or strings to the device.
– The device must not receive broadcast commands from the controller of the PV inverter. This device
should only receive commands from an external controller/regulator (control system/SCADA)- RPO react-
ive power requirements.
– For reliable operation, an automatic re-start of the device will take place regularly (on Sunday 12:00
o'clock).

3 Description of the device
3.1 Mode of operation
The device has been developed specifically for the provision of reactive power.
To implement reactive power control at the grid connection point, the control system reads the measured re-
active power at the grid connection point.
If the actual value is different to a specified value, additional reactive power can be ordered from this device, in
this way the reactive power at the grid connection point can be compensated or the device operates according
to static specifications.

6 Assembly and preparation
6.1 Choosing the installation location
DANGER
Risk of fatal injury due to fire or explosions!
Fire caused by flammable or explosive materials in the vicinity of the device can lead to serious injuries.
1. Do not mount the inverter in potentially explosive atmospheres or in the vicinity of highly flammable ma-
terials.
CAUTION
Property damage due to gases that have an abrasive effect on surfaces when they come into contact with
ambient humidity caused by weather conditions.
The device housing can be seriously damaged due to gases in combination with air humidity resulting from weather con-
ditions (e.g. ammonia, sulphur).
1. If the device is exposed to gases, the installation must be carried out at observable locations.
2. Perform regular visual inspections.
3. Immediately remove any moisture from the housing.
4. Ensure adequate ventilation at the installation location.
5. Immediately remove dirt, especially on vents.
6. Failure to observe these warnings may lead to device damage which is not covered by the manufacturer warranty.
NOTE
Access by maintenance personnel for service
Any additional costs arising from unfavourable structural or installation conditions will be billed to the cus-
tomer
Installation space
– As dry as possible, climate-controlled, the waste heat must be dissipated away from the device.
– Unobstructed air circulation.
– Close to the ground, accessible from the front and sides without requiring additional resources.
– Protected on all sides against direct weather exposure and sunlight (thermal heating) in outdoor areas. Implementa-
tion where necessary via constructional measures, e.g. wind breaks.
– For easy operation during installation, ensure that the display is slightly below eye level.
Installation surface
– Must have adequate load-bearing capacity
– Must be accessible for installation and maintenance
– Must be made out of heat-resistant material (up to 90 °C )

NOTE
Power reduction due to heat accumulation!
If the recommended minimum clearances are not observed, the device may go into power regulation mode
due to insufficient ventilation and the resulting heat build-up.
1. › Observe minimum clearances and provide for sufficient heat dissipation.
2. All objects on the device housing must be removed during operation.
3. › Ensure that no foreign bodies prevent heat dissipation following device installation.

Property damage as a result of condensation
During pre-assembly of the device, moisture can penetrate into the interior via the dust-protected threaded connections.
The resulting condensate can cause damage to the device during installation and start-up.
üKeep the device closed during pre-assembly and do not open the connection area until you perform installation.
1. Seal off the screw connections using sealing covers.
2. Prior to installation, check the inner area for condensation and if necessary, allow it to dry sufficiently before installa-
tion.
3. Immediately remove any moisture from the housing.
