Chapter 4: Installation
BEWARE!!
The data line must be locked at both sides with a
120 Ohm line resistance and must be supplied a
firm potential using the two link plugs on the two
jumpers on the circuit board of the display of all la-
test TOPAX DX versions.
Two link plugs/jumpers have to be connected to the TOPAX DX
(the last one in the network) for the 10 ohm switch, Pull-up
and Pull-down resistances. The resistances are not active in its
delivered state.
The jumper plug-in slots are located in the upper casing on the
display board, above the flat band-connection to the main board
(see fig. 4.7).
OFF
- delivery status
- resistances are NOT activated
- jumpers are set down
ON
- in the network
- resistances are activated
- jumpers are set up

on the last TOPAX DX in the network.
TopView Software
For the remote indication a visualization program is offered in
two versions. One of them, the program TopView mini, is free of
charge and can be downloaded from Internet on.
4.5 Power connections
The equipment may be installed and attached only by authorized
and qualified electricians. The connection has to take place as
per the attached terminal diagrams.
Insert the cables in the various connections screwed on the bot-
tom side of the housing. After the installation, tighten all cable
connections so that the required protection class is provided (see
Fig. 4.8).
Fig. 4.8:Connections screwed, to reach the required protection class.
For the connection to the power supply and to the actuators,
TOPAX DX is equipped with special terminal clips (see Fig. 4.9).
For a better assembly these clamps are designed plug-ins,
whereby the maximum cross section is .5 mm for the power
cord and 1.5 mm for all other cable to the terminal clips (see
Fig. 4.10),.

technical components.
BEWARE!
When selecting cables and lines as well as when
installation connecting the equipment to other elec-
trical peripheries make sure to comply with the regu-
lations of VDE 0100 for high voltage systems (rated
voltages up to 1000 V) and/or the respective natio-
nal regulations of your country!
BEWARE!
The equipment is not suitable for the installation in
explosive conditions!
