Safety
Before using the product for the first time, please read through the safety instructions carefully.
DANGER
Lethal voltages are still present in the connections and cables of the device even after the device has
been switched off and disconnected!
If the load on the DC side is disconnected (e.g. by shutting down the battery), the device does not shut
down. DC voltage is still present at the connections. Severe injuries or death may occur if the cables and/or
terminals/busbars in the device are touched.
›
Comply with all safety regulations and current technical connection specifications of the responsible
power supply company.
›
The device is only permitted to be opened or serviced by a qualified electrician.
›
Switch off the grid voltage by turning off the external circuit breakers.
›
Check that all AC and DC cables are completely free of current using a clip-on ammeter.
›
For work on the device, ensure complete isolation from the power supply on the AC and DC connec-
tions.
›
Do not touch the cables and/or terminals/busbars when switching the device on and off.
›
An AC- and DC- disconnecter unit must be provided during the final installation stage.
›
Do not make any modifications to the device.
›
Keep the device closed when in operation.
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.
When working on the battery, it is also necessary to switch off the DC voltage with the DC isolator switch in addition to
disconnection from the grid.
2.1
Proper use
The device has been developed for use with a battery system. The device converts the DC voltage provided by the battery
into AC voltage, so that it can be fed into the grid or the battery can be charged. The device is built using state-of-the-art
technology and in accordance with the recognised safety rules. Nevertheless, improper use may cause lethal hazards for
the operator or third parties, or may result in damage to the device and other property. This relates to the following oper-
ation and connection:
Operate the device only with a permanent connection to the public power grid.
Operation in accordance with the appended EU Declaration of Conformity envisages up to 4 bidirectional feed-in in-
verters per battery.
Approval from KACO new energy is required for a parallel DC circuit with more than 4 bidirectional feed-in inverters.
Any other or additional use is not considered proper or intended use and can lead to an annulment of the product guar-
antee. This includes:
Mobile use
Use in rooms where there is a risk of explosion
