• Description of the application and
• Description of the error that has occurred
The accompanying letter for repair can be downloaded online from the manufacturer's website
(use the search function if necessary).
Protection against electrostatic discharge (ESD)
(ESD = electrostatic discharge)
To prevent damage from ESD, electronic modules or components must be handled, packaged,
and stored in an ESD-protected environment. Measures against electrostatic discharge and
electrical fields are described in DIN EN 61340-5-1 and DIN EN 61340-5-2 "Protection of elec-
tronic devices from electrostatic phenomena".
When returning electronic modules or components, please note the following:
• Sensitive components must only be packaged in an ESD-protected environment. Work-
spaces such as this divert electrostatic charges to ground in a controlled manner and pre-
vent static charges due to friction capacities.
• Only use packaging for ESD-sensitive modules/components. These must consist of con-
ductive plastics.
No liability can be assumed for damage caused by ESD.

1 Introduction
1.5 Brief description
The router module is used to achieve decentralization within the automation system, which
means that the input/output modules are dispersed to several DIN rails/switch cabinets. A dis-
tance of up to 100 m can lie between two router modules, between a router module and a base
unit, or between a router module and a multifunction panel. A maximum of 30 router modules
and a maximum of 30 input/output modules is possible in a system.
LEDs are used to indicate applied voltage supply and the operating status of the module.
The electrical connection of the voltage supply for the router module is carried out at the front
through a removable terminal strip.
No configuration of the router module is required. The router module is simply integrated into
the overall system by the setup program. For special applications such as hot-connect the ad-
dress of the router module can be set by rotary coding switches.
For service work, the module insert can be easily pulled out of the case at the front. The case
including the bus PCB remains mounted on the DIN rail.

2.1 General information on installation/dismounting
Mounting site
All modules have protection typeIP20 and are only intended for use in fireproof controlcabinets
or switch boxes. The mounting site should be virtually vibration-free. Electromagnetic fields
caused by equipment such as motors or transformers should be avoided.
Multifunction panel 840 has protection type IP67 at the front and is intended for installation in
a panel cut-out. The rear has protection type IP20.
Climatic conditions
The ambient temperature and the relative humidity at the mounting site must correspond to the
technical data. Aggressive gases and vapors have a negative effect on the operating life of the
modules. The mounting site must be free from dust, powder, and other suspended matter so
that the cooling slots do not become blocked.
DIN rail All modules are mounted on a DIN rail according to DIN EN 60715 (35 mm × 7.5 mm × 1 mm).
For reasons of stability, the spacing of the fastening screws for the DIN rail should not exceed
200 mm. The minimum distances for the modules that are specified in the module-specific in-
stallation or operating instructions must be observed.
Installation position
The DIN rail should be mounted horizontally so that all modules are arranged vertically. Other-
wise the admissible ambient temperature range will be restricted.
Space requirement
The modules require the minimum distances shown in the following figure for the purpose of
installation/dismounting and for future maintenance or replacement. In the event of shorter dis-
tances the minimum bending radius of the cables, the performance of the electrical installation,
and the clear arrangement of the plant are no longer guaranteed.
DANGER!
With multichannel controller module 705010 and relay module 705015, the load circuits from
relay or solid state relay outputs can be operated with a dangerous electrical voltage (e.g.
230 V).
There is a risk of electric shock.
Prior to the installation/dismounting of these modules or the removal of the module insert, the
load circuits are to be disconnected from the voltage and the terminal strips are to be re-
moved from the module. This work must only be performed by qualified personnel.
WARNING!
The modules must never be installed in areas with an explosion hazard.
There is the risk of an explosion.
The entire system must only be used outside of areas with an explosion hazard.

Minimum distances
2.2 Installation/dismounting on DIN rail
All modules in the system are intended for installation on a DIN rail according to DIN EN 60715
(35mm×7.5mm×1mm).
The following must always be installed on the left, at the start of the DIN rail:
• A central processing unit or
• A router module
These modules connect the input/output modules to the voltage supply and the system bus.

NOTE!
To determine the required minimum width of the DIN rail, the widths of the individual modules
are to be added (see technical data of the modules in the respective data sheet or the
module-specific installation instructions).
The widths of the cover (17.5 mm) and both end brackets (each 9.5 mm) should also be
taken into consideration: 17.5 mm + 2 × 9.5 mm = 36.5 mm.
NOTE!
Modules with a recent production date have two fixing knobs on the right side of the case and
on the left two round holes (for greater torsional strength of the entire module assembly). If a
module with fixing knobs is to be inserted into an existing module assembly and the adjacent
module does not have the corresponding holes, the fixing knobs must be completely re-
moved to ensure electrical contact between the modules. For example, a cutter knife and a
file can be used for removal.
