Replace DC fuse

↻ Ensure there is no DC voltage present.
. NOTE: Do not damage or remove lateral insulator attachment!
1. Loosen and remove the DC fuse on the upper and lower lock nuts by holding the
support bolt against it. [ W35] against it [ W17].
2. Insert the new specified DC fuse in the intended position and fasten it with the
lock nuts by holding the support bolt [ W35] against it [ W17 /
3. DC fuse replaced. Continue connecting the battery.

11.6.1 Procedure
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.
1. If a fault occurs, notify an appropriately authorized and qualified electrician or KACO new energy GmbH
Service.
2. The operator can only carry out actions marked with a B.
11.6.2 Rectifying a fault
B = Operator's responsibility ; E = The indicated work may only be carried out by an authorised electrician. ; K
= The indicated work may only be carried out by a service employee of KACO new energy GmbH!
Error Possible cause
The LEDs do not light up Grid voltage not avail-
able
The device stops feeding Defective circuit-break-
into the grid shortly ers in the device
after being switched on,
even though there is
sunlight present.
Device is active but not Grid-feed is interrupted
connected to the grid. A due to a grid fault.
grid fault is displayed on
the status LED.
The grid fuse trips. The grid fuse capacity is
too low.

5 Nm].
Explanation/remedy
› Check whether the DC and AC voltages are within the permit-
ted limits (see Technical Data)
› Notify KACO Service.
If the circuit-breakers are defective, the device will recognize
this during the self-test.
› Ensure that there is sufficient PV generator power.
› 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 stopped the feed-in process and disconnected from
the grid for safety reasons.
› Change the grid parameters within the permitted operating
limits (see the "Start-Up" section).
In case of a high level of solar radiation, the inverter exceeds its
rated current for a short period, depending on the PV gener-
ator.
Select the capacity of the device's backup fuse to be somewhat
higher than the maximum feed-in current (see the "Installa-
tion" section).
› Contact the grid operator if the grid failure continues to oc-
cur.
