5.1 Mounting
the
gas-net C1 / C2
The
gas-net
devices are designed for mounting in a 19”-cabinet; the
gas-net
C1
has a mounting width of 1/6 whereas the width of the
gas-net
C2 is 1/3.
A mounting depth of 170 mm must be taken into consideration to leave the ter-
minals on the back accessible. We recommend mounting the device in a swing
frame.
The gas-net devices must be installed in an explosion-free plant area
(where electrical appliances are located) according to protection class
IP 20.
5.2 Line
Connection
The device must always be load-free during the connection of the generator,
supply, signal and data lines.
Any modification of the wiring is only permitted if the supply has been
disconnected before!
The connection of the signal lines to the
gas-net
device is implemented via plug-
gable screw terminals each of which is located in a cable terminal box. The
power supply is connected via fixed screw terminals. Data lines have to be con-
nected to the according SUB-DB9 connector housings.
Please consider the relevant installation guidelines when arranging the wiring.
The lines must be tensile stress-free and must be provided with a bend protec-
tion, if the
gas-net
device is mounted in a hinged bay. The cable length must be
dimensioned in such a way that there is no tensile stress on the cable during the
swinging of the swing bay.
5.2.1 Power supply and earthing
Operate the
gas-net
C1 or C2 device with a nominal voltage of 24 V DC.
The connection of 24 V is implemented via the terminals
+
and
–
on the back of
the device and must be protected externally against short circuits with 1 A. The
internal device protection is guaranteed by a self-resetting overcurrent protector.
Connect the protective earth to
PE
of the power supply socket for equipotential
bonding.
