Installation instructions
Product description
The SAP14 is a power supply unit suitable for an E-Bus
and has an output voltage of 12 V at a maximum of 1.3
A. The housing offers space for four type SMT12 (transponder) and for a battery of up to 12 V, 17 Ah for VdS
applications or up to 12 V, 17 Ah for non-VdS
applications. At least one SMT12 must be fitted to use
the cover tamper contact.

Risk of electrical shock
z Ensure that the connection is secure and the circuit
breaker to the supply circuit is easily accessible when
operating the unit (e.g. fuse up to 16 A).
z Do not connect any external consumers to the fuse.
z Grounding has to adhere to the respective safety
regulations.
Device damage due to overvoltage
z Connect the unit only to current sources with the
specified voltage. Information on the power supply is
available on the power supply unit / rating plate.
Risk of panic reactions
z Prior to testing the system, make sure all important
persons involved and supporting authorities are
informed.
z To avoid panic, all involved should be informed prior to
testing alarm facilities.
Danger of explosion
z Make sure that the battery poles do not short circuit.
z Please pay attention to battery polarity.
z Always fasten the battery in place with the holder
intended for this purpose.
