Shutting down for maintenance / troubleshooting

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.
Only appropriately qualified electricians authorised by the mains supply network operator are permitted to
open and maintain the device.
1. › Comply with all safety regulations and current technical connection specifications of the responsible
power supply company.
NOTE: Shutdown sequence
F Switch off the grid voltage by turning off the external circuit breakers.
ð After shutdown, wait 5 minutes before opening the device.

Maintenance and troubleshooting | 11
Explanation/remedy
› Check whether the AC voltage is within the permitted limits
(see Technical Data)
› Notify KACO Service.
If the grid separation relay is defective, the device will recog-
nise this error during the self-test.
› If the grid separation relay is defective, have it replaced by
KACO Service.
› Notify KACO Service.
Due to a grid fault (over/undervoltage, over/underfrequency),
the device stops providing reactive power and disconnects
from the grid for safety reasons.
› Change the grid parameters within the permitted operating
limits (see the "Start-Up" section).
If the grid fuse trips immediately, the device's hardware is
probably damaged.
› Contact KACO Service to test the hardware.
› No action.
When there are certain ambient conditions, the devices may
emit audible noises. Grid interference or grid failure caused by
particular loads (motors, machines, etc.) which are either con-
nected to the same point on the grid or located in the vicinity
of the device. Under particular grid conditions, resonances may
form between the device's input filter and the grid; these may
be audible even when the device is switched off. These noise
emissions do not affect the operation of the device. They do
not lead to loss of performance, failure, damage or to a short-
ening of the device's service life. People with very sensitive
hearing (particularly children) are able to hear the high-fre-
quency hum caused by the device's operating frequency of ap-
proximately 17 kHz.
