2.2 Installation
2.2.1 System Assembly
For assembly mount the products on a top hat rail according to EN
50022. There are two possibilities:
A) Operating with supply set 716425 (Supply terminal and End
block)
ΠSnap on the supply terminal on the left side. The terminal includes
the end stop function. The supply terminal is connected to the PSU
(DC 12/24V, 40A).
• Alongside of the supply terminal (right side) the needed number of
control devices 716410 can be mounted.
Ž Mount the end stop terminal.
• To get an electrical connection between supply terminal and
control device cut the copper rail 716426 to a suitable length.
Calculation: 18mm + 8,1mm x n. The copper rail has to be
snapped into the relevant slots of the supply terminal and end stop terminal.
• To contact the single control modules, move the contact slide on the copper rail by using a screw
driver. The load is connected to termination point (1). The minus potential of the load must be
connected directly to the users power supply. This also applies to the minus potential (5). For all
other functions, see the function plan on the next page.
‘ If required, the copper rail can be covered by a plastic cover 716427 between supply terminal and
end terminal. The pre cut part is based on the calculation: L = 6mm + 8,1mm x n.

User Manual LOCC-Box, LOCC-Pads
LOCC-Box-Net_1.61_HB_EN 9
Der max. Strom einer Einspeiseklemme beträgt 40A. Um einen Strom > 40A in
das System einzuspeisen können, empfehlen wir die zusätzliche Verwendung
einer oder mehrerer Einspeiseklemmen vom Typ 716421. Somit ist ein
Maximalausbau mit 160A möglich (begrenzt durch die 3x10mm Kupferschiene).
B) Direct voltage supply of the control unit
Instead of powering the system via the supply terminal, it is possible to power the system via the
termination point (6). A power supply of DC 12/24 V is needed. All other functionalities correspond
to description A).

module for 1 sec. The displayed number increments by 1 and
the next module can be assigned. This process has to be

chapter 3.5.11.
An additional Reset of the default status is possible over the push button. See

Searching modules with a node number > 0
After clicking Search, the internal bus is checked for
connected modules. All modules with a node number
between 1 and 254 will be displayed in the LOCC-
Box Node window.
Modules with the node number 0 or the same node
number are also recognized. These modules have to
be configured.
The window Search Node appears.
In the following example two modules with the node number 6 were
found.
After configuring node number 7 the search restarts.
This process will be repeated till all modules are
assigned to a valid node number (accept 0).
