To comply with safety regulations, it is necessary to install an external surcharge
protection device for this equipment. This can be achieved by using a 5.0 A time-
lag fuse or a previously approved 1-amp thermo-magnetic circuit breaker such as
the ABB-S281-UC-K-1 or an equivalent model. It is crucial to ensure the correct
polarity of the DC connection, as connecting it incorrectly may result in damaging
the external line fuse.
The Teldat 5Ge-Rail is equipped with one earth terminal located on the rear pan-
el. It is essential to ground it using a cable with a section measuring at least 2 mm
(AWG14).
This equipment must be properly grounded. Never deactivate the ground conduct-
or or operate the equipment without a correctly installed ground. If you are unsure
about the availability of suitable grounding, it is recommended to contact the ap-
propriate electrical inspection authority or an electrician. During the installation or
replacement of the unit, always establish the ground connection first and discon-
nect it last.
