1. Configuration
1.1 Power Supply
Bus modules require a direct-voltage power supply of typically 24 VDC (SELF/PELF) which
must comply with the regulations of conventional industrial power-utility companies.
In order to optimize immunity from interference, we advise you to power
sensors, bus, and actuators from different sources. The power supply should
be primary switched-mode or regulated power supplies.
The output of the power supply units is dependent on the number of connected electrical
consumers and their output.
In any case, it must be ensured that the system voltage does not drop below
18 VDC viewed from the system power supplies and measured at the
remotest slave. System response becomes unspecific if sensor and bus
power supply drops below 18 VDC.
Primary switched-mode power supply units normally permit an increase in
output voltage to the amount of the rated voltage in order to compensate for
any power losses.
Modules with digital inputs support the direct connection of commercially available sensors. A
separate power supply may be necessary for the sensors if the total power requirement is high
due to the number of slaves or the sensors have a high power draw.
Recommended "MCS Power" power supply units
Primary switched-mode power supply units from the MCS Power series are specially designed
to power automation systems. For this reason, we recommended them to power the modules.
Please refer to our accessory information on page 36.
Wire Cross-Sections
The wire cross-section may be max. 1.5 mm². It is limited to this maximum cross-section by the
7/8“ connector.

1.2 Electromagnetic Compatibility (EMC)
This device meets the requirements of EC Directive 89/336/EEC "Electromagnetic
Compatibility".
This device is Class A equipment and causes radio-frequency interference in
residential areas. In this case, the operator may be required to implement
adequate countermeasures.
The devices described in this manual each meet the relevant standards for electromagnetic
compatibility. However, this does not mean that their electromagnetic compatibility is still
guaranteed when fitted to a plant or machine.
For this reason, we urgently advise you to comply with the instructions on installation in
accordance with EMC requirements below. Only then can you assume that the overall system
complies with EMC requirements, provided CE-marked components are used exclusively.
Protection Against Electrostatic Discharge
The products described in this manual contain complex semiconductor components which may
be destroyed or damaged by electrostatic discharge (ESD).
Damage does not necessarily lead to immediate, detectable failure, or malfunction. These
states may be even delayed, or occur sporadically.
The generally accepted safety precautions for ESD sensitive devices must be observed when
handling the devices. The following precautions in particular must be taken:
Never unplug or plug in connectors live.
If you are an operator, discharge any static charge you may be carrying just
before you touch equipment. For example, you can touch a grounded part of
the machine, or wear an ESD discharge strap permanently connected to
ground.
Grounding
A short (as short as possible), low-impedance connection between the grounding point and the
reference ground is essential to divert interference voltages running between the device and
reference ground.
The inductance of standard FE conductors is a high impedance for high-frequency interference
voltages. For this reason, the use of grounding straps is advisable. If this is not possible, a fine-
wire FE conductor should be selected with the largest possible cross-section, and the
connection to ground should be kept as short as possible.

Cable Routing
You can avoid EMC problems by observing elementary basic rules of cable routing:
Route data lines as far away from power lines as possible.
Route data lines and power lines at least 10 cm apart.
Only intersect data and power lines at right angles.
Route data and power lines in separate, shielded compartments.
Remember the interference potential of other devices or lines when you route the cables.
Place frequency converters, motor lines, and other devices and lines that emit high-
frequency interference at the greatest possible distance.
Blackouts and Brownouts
Transient voltage cutoffs (<10 ms) normally pose no operational problems as the electronics are
protected by capacitors integrated in the power circuits. This does not apply to the power
supplies of the sensors and actuators connected to the module. Their high power requirement
cannot be covered by the capacitors integrated in the device. For this reason, even transient
interruptions in actuator voltage result in undesirable switching operations.
Due to the integrated input filter, a change in the input signal of less than 1 ms leads to no
change in the input state signaled to the Master. Longer interruptions in sensor supply may lead
to input signal changes.
Separate Power Supplies
Sensors or actuators can be powered by common power supply units. However, it is preferable
to use separate power supplies in order to maximize the electromagnetic compatibility of the
overall system.
Interference Suppression of Inductive Loads
The outputs of the devices described in this manual have an integrated protective circuit that
provides safety against high-energy interference voltages, such as those that occur when
inductive consumers are switched.
Fig. 1: Interference Suppression of Inductive Loads
A suppressor diode helps to reduce quickly the energy stored in the inductive load of a
magnetic field. However, it is recommended to use commercially available protection circuits for
inductive loads, especially loads in the range of the maximum current-carrying capacity of a
channel at switching frequencies of > 1 Hz. These protection circuits can reduce the energy
stored in the connected inductances.

V 1.6 7
The high voltages that occur when inductive loads are shut down result in strong fields in the
cables with consequential faults in adjacent circuits or devices.
Murrelektronik GmbH can supply you with a wide selection of interference
suppression products for this purpose.
Please refer to our catalog or visit www.murrelektronik.com.
Other Measures and Limits
In some system configurations, the requirements for interference emission and immunity from
interference can only be met with additional measures, or even not at all. In these cases, the
EMC within the system is also dependent on the single components of other manufacturers.
Mains filters are a suitable means of reducing line-conducted interference.
Various manufacturers offer optical-fiber converters. This data transmission technology is
basically immune to EMC interference. However, this does not apply to the electronic
conversion circuits. For this reason, the use of optical fibers does not solve all EMC
problems.
Our certified test center is available to answer any further queries you may
have on EMC. There, you will also receive advice on guaranteeing
compliance with the EMC Directive for the systems you produce.

1.3 Replaceability
IMPACT67-P modules can replace the phased-out MBV-P modules. This means that modules
of identical type are physically replaceable. It is no problem to replace an MBV-P module with
an IMPACT67-P module. Channel assignment and diagnostic messages are identical. It is also
unnecessary to load a new GSD file. IMPACT67-P modules are capable of running with
MBVP3101.gsd. The MURR3101.gsd file is available for new configurations, or for adapting an
existing configuration to the current article numbers of IMPACT67-P modules. The table shows
the replaceability in each case.

2. Installation
2.1 Mounting
Modules of the IMPACT67-P product lines can be mounted directly on an installation wall or on
a machine. Two mounting holes are provided for this purpose in the module.
Before mounting a module, make sure the mounting surface has no unevenness that will cause
mechanical stresses in the housing.
Two bolts with a diameter of 6 mm and two DIN 433 T1/T2 washers are required to mount each
module. The correct tightening torque is 3 Nm.
Fig. 2: Figure: Mounting dimensions
We advise you to maintain a minimum spacing of 3 mm when mounting the
IMPACT67-P to guarantee professional installation and enhanced heat
dissipation.
Angled plugs from Murrelektronik require a minimum spacing of 50 mm.
