2.4.1 Power Supply Unit Specifications
All DC power supply specifications are contained in
Chapter 9 Technical Data System
6842 GPS Slim Line (1U)
.
2.4.2 Fusing
Pay attention to the correct fusing of the power supply when connecting the System 6842
GPS Slim Line (1U).
The corresponding performance data can be taken from the equipment nameplate. The
System 6842 GPS Slim Line (1U) is currently fitted with a power supply unit with a power
consumption of max. 40VA.
If the internal fuse (device protection) trips it is highly probable that the
equipment is faulty. In this case the device should be checked in the
factory.
2.4.3 Reverse Voltage Protection
The version of System 6842 GPS Slim Line (1U) with DC supply has reverse voltage
protection. This protection prevents damage to the equipment due to an incorrectly
connected DC power supply.
Protection is effected by means of a self-resetting fuse. In the case of reverse polarity, it is
necessary to switch the equipment off for approx. 20 seconds after this fuse has tripped. The
power supply can then be connected with the correct polarity.
