TOPAX
®
DX
Multichannel controller
Two link plugs/jumpers have to be connected to the TOPAX DX (the last
one in the network) for the 120 ohm switch, Pull-up and Pull-down re-
sistances. The resistances are not active when the system is delivered.
The resistance of 120 ohms on the PC side is applied via the connector
converter.
The jumper slots are located in the front of the housing on the display
board, above the flat band-connection to the main board (see Fig. 7).

4.4.6 TopView software
For remote viewing on a PC the manufacturer offers the full version of
the TopView display program and a freeware version with limited func-
tionality. The "TopView Mini" freeware version is free on the internet and
can be downloaded from the manufacturer's website.
4.4.7 Connection to a computer via Ethernet (option)
The Ethernet interface provides a further method with which to integrate
the TOPAX DX in the network. The Ethernet interface can be set up using
an internal intranet. This network still enables telemaintenance.
4.5 Electrical installation
The equipment may be installed and attached only by authorized and
qualified electricians. Connections must be made according to the en-
closed wiring diagrams.
ATTENTION!
Only work on electrical connections while the device
is disconnected from the power supply.
Insert the cables in the various connections screwed on the bottom side
of the housing. After the installation, tighten all cable connections so
that the required protection class is provided.

housing.
For the connection to the power supply and to the actuators, TOPAX DX
is equipped with special terminal clips (see Fig. 9). For a better assem-
bly these clamps are designed as plug-ins (see Fig. 10), whereby the
maximum cross section is 2.5 mm
2
for the power cord and 1.5 mm
2
for
all other clamps.

installation.
ATTENTION!
When choosing the line material, for installation and
electrical connection of the device, observe the reg-
ulations of VDE 0100 "Provisions for setting up elec-
tric power plants with nominal voltages below 1000
V" or the individual national rules.
ATTENTION!
The equipment is not suitable for the installation in
areas with a potentially explosive atmosphere.
