Important note
- If several power supplys are used for increasing the emergency power capacity, the 0 V potentials of all power
supplys must be interconnected via KL103/KL104.

Fault messages can be switched through to
collective fault with S100.
The respective switch must be at the "ON”
position.
S100/1 Fault - external user
S100/2 Mains fault
S100/3 Accumulator defective (<9.45 V)
S100/4 Charger controller defective
For VdS compliant applications, the following
settings apply:
S100/1 = OFF
S100/2 = OFF
S100/3 = OFF
S100/4 = OFF
Wire Jumpers:
DB100: Open, when the non-fused earth
conductor registers faults
DB101: Open during continuous operation
without accumulator
(not Vds-compliant)
DB102: Open, when external NCT is
connected
Before opening the housing, wait
until the electrolytic capacitors are
discharged (approx. 3 minutes).
Please observe Chapter 2 and 3
in these instructions!
