1. General
The accumulator buffered DC supply guarantees a safe backup of the DC supply in case of a mains failure.
Every other use is strictly excluded.
The operating instructions must be read prior to use or installation; all instructions have to be considered!
Commissioning and maintenance may only be performed by qualified specialist personnel.
All warranty and guarantee claims could be lost in case of non-observance or unauthorised modifications!
This power supply is only a built-in unit with VdS certification. For a proper VdS installation the external power
supply must be installed in a housing with protective system IP30 or better. Furthermore the temperature sen-
sor which is optionally available must be installed for temperature tracking

General safety notes
NOTE
The operating instructions must be read prior to installation or use of the unit. The instructions
must be observed. All warranty claims could be lost in case of non-observance!
DANGER
Only specialised electricians are authorized to commission and maintain the unit. Improper han-
dling with voltage procedures or lead accumulators can lead to electric shock and severe burns.
DANGER
All work on the unit may only be performed in de-energized state!
The five safety rules must be observed.
Input and output lines must be sufficiently dimensioned and fused!
Never open the housing. Repair may only be done by the manufacturer!
Non-observance can lead to fatal electric shocks.
CAUTION
For use in a controlled environment refer to chapter 11 Technical Data for environmental condi-
tions.
NOTE
In case of malfunction we recommend to send the unit to the manufacturer
The unit has been developed for protection class I and has the degree of protection IP20. Operation is only
admissible in dry rooms. The operation is only allowed in closed housings. This device is designed for pollu-
tion degree 2. The applicable VDE regulations, in particular VDE 0100 and EN 60204, must be observed!
The admissible ambient temperature range must be observed!
The DC output circuit must be fused externally in order to avoid overload! (See section 3.2)
The two energy sources (mains and lead accumulator) must be separated in order to de-energize the unit on
the output side!
Only the lead accumulator types specified for the unit must be used! The change of lead accumulators must
only be performed when the unit is de-energized! (see section 7.2). If external buffer accumulators are used,
accumulator safeguarding must be performed by the user! For safety reasons, the safeguarding element
(overload and short circuit protection) must be arranged in close proximity to the accumulator set! If lead ac-
cumulators are used, sufficient air flow must be provided according to VDE 0510, part 2.
Never interconnect new and used lead accumulators, or lead accumulators of different types or from different
manufacturers.
Used lead accumulators must be disposed carefully.
