POLARIS
PROFESSIONAL- for Zone 2/22
POLARIS Panel PC Professional 10,4" / 12,1" / 12,1" W
As a result of the connection of the power supply to the POLARIS, the earth for the
power supply is connected to the PE. It is essential to ensure that the earth for the power
supply on the POLARIS, if this is not electrically isolated, indicates no potential
difference to the PE/PA.
The POLARIS PROFESSIONAL is fused internally in the DC model with a 4 A slow-blowing
fuse and with the AC model with a 1.6 A or 2.5 A slow-blowing fuse. The fuse may be
triggered in the case of voltage breaks or under-voltage.

We recommend that the POLARIS is secured with a back-up fuse to avoid triggering the
internal fuse in the device. The internal fuse can only be replaced by BARTEC.
Back-up fuse AC: 1.6 A slow-blowing (since June 2015: 2.5 A)
DC: 4 A quick-blowing.
The I
value is to be observed for other versions of the fuses.

Certain basic measures must be taken to ensure freedom from interference when the
POLARIS are installed:
The interference voltages coupled into the device via power, data and signal line
–
and the electrostatic voltage caused by contact are to be dissipated through the
equipotential bonding.
The installation point should be as far as possible away from fields of
–
electromagnetic interference. This is especially important if there are frequency
converters in the vicinity. Under certain circumstances will it be advisable to set up
partitions to isolate the graphic display from interference.
If inductive devices are fitted in the vicinity (e.g. contactor, relay or solenoid coils),
–
especially if they are powered from the same source, protective circuits (e.g.
RC elements) must be installed.
Power supply and data cables must be laid so as to avoid interference. This can be
–
achieved, for example, by avoiding laying such cables in close proximity to high-
current carrying cables.
