1.11 Product description
A familiar problem for manufacturers of machinery and pluggable devices:
Due to modern drive regulators such as frequency converters or servo controllers, the
operational leakage current of the device or machine may increase.
However, DIN EN 50178/VDE 0160 only permits an operational leakage current of up to 3.5
mA AC. If this value is exceeded, the standard stipulates that the protective earth requires a
fixed connection. This limits the mobility of the machines or devices.
However, this leakage current can be minimised through the careful arrangement of the
individual components as well as with complex network filters. Unfortunately, this
implementation is usually too expensive, and in many cases the operational leakage current
is still above 3.5 mA due to the system.
The notion of the standard is reasonable and understandable as it protects the users of the
machines or devices from electric shock if such a device is disconnected from the
protective earth system due to a defective connection cable, plug or extension cable. But in
addition, the standard expressly allows higher leakage currents if the availability of the
protective earth system is permanently monitored. This is where the PECON+
®
comes in.
The PECON+
®
is a monitoring device that is installed directly at the feed point of the mobile
machine.
The quality of the protective earth is permanently monitored by the PECON+
®
. If it is
working flawlessly, the integrated signal contact of the PECON+
®
releases the main
contactor of the machine.
The device, which is only 45 mm wide, is mounted on a DIN rail and reliably monitors all
common voltage ranges.
The PECON+
®
is used for monitoring the protective earth of single phase and 3-phase
pluggable consumers. Depending on the product, polarity reversal of phase (L) and neutral
conductor (N) is also monitored. Other product variants with special functions are also
available.
The PECON+
®
IT is available for networks without neutral conductor (N).

1.12 Area of application
Leakage current >3.5 mA = danger to life!?
Manufacturers and operators of machinery as well as portable or mobile electrical devices
are equally affected. If an electrical device continuously exceeds a leakage current of AC
3.5 mA (in some regulations the limit is set to AC 10 mA) during normal use, it is subject to
special regulations.
Why this strict limit?
When a residual current circuit breaker (RCCB) is used, you can rest assured that the
personnel is adequately protected. Or are they?
Of course not every instance of touching electricity leads to injury or even death. If a live
object is merely touched, the person generally removes the affected body part from the
danger by virtue of the natural muscle reflex.
A more critical danger presents itself when we clasp a live machine part. Door handles,
control levers, climbing aids etc. present typical risks. Internationally recognised standards
already define body currents of only 15 mA as a "release limit", meaning that the muscles of
the energised body part cramp and render the victim unable to release their grip.
All is well for the residual current circuit breaker!
Innovative machine concepts and electromobility often cannot be realised without inverters,
frequency converters, servo drives or intelligent charging concepts.
In most instances, mains filters with Y capacitors (C between outer conductor and PE) are
used for EMC reasons. However, two small Y-suppressor capacitors of only 100 nF can
already cause leakage currents well above the 10 mA limit.
This is where VDE, TÜV and BG come in:
Producing leakage currents for trouble-free operation is generally permitted. However,
developers are obliged to ensure that the electrical equipment is equipped with suitable
protective earthing. Only then can the risk of a dangerous potential increase of touchable,
conductive parts of the machine be safely ruled out.
In general, the relevant standards (e.g. DIN EN 50178) equally permit the following
solutions for leakage currents AC > 3.5 mA:
- Installation of a second protective earth
- Installation of a separate isolating transformer
- Automatic disconnection of the power supply if the protective earth is interrupted

2 Safety instructions
2.1 Intended use
The EPA PECON+
®
is used to safely monitor and automatically disconnect the power
supply in the event of interruption of the protective earth (PE) in single and 3-phase
networks in accordance with standard DIN EN 50178 / VDE 0160:1998-04.
The PECON+
®
determines the availability of the protective earth of consumers (usually
pluggable connected) by measurement and actuates an internal release relay if the
protective earth is present.
The monitoring device must be installed directly on the feed point of the machine/system.
Depending on the product, the polarity reversal of phase (L) and neutral conductor (N) is
also monitored and reported. Other product variants with special functions are available,
e.g. for switching phases and the neutral conductor after release (for all PECON+
®
NV
variants).
The PECON+
®
IT is available for networks without neutral conductor.
NOTE
Particular attention should be paid to the safety instructions and the technical data
setting out the ambient conditions.
2.2 Inadmissible operating conditions
CAUTION
The PECON+
®
must only be used under the conditions and for the purposes for which
it was designed (see section "Intended use").
Operational safety is not guaranteed in the event of modification or improper use.
The device is not suitable for reducing leakage currents.*
The PECON+
®
does not replace a residual current device.
High voltage differences between the neutral conductor and the protective earth
conductor can overload or destroy the device.
Strong electromagnetic fields can affect the function of the device.
External mechanical loads are not allowed.
Use in potentially explosive atmospheres is prohibited.

qualified personnel.
Qualified personnel as defined by this instruction manual are
electricians who are familiar with the installation, assembly, startup and operation of
the device, with the hazards involved, and who, based on their technical training, are
also familiar with the relevant standards and provisions.
Repairs may only be carried out by authorised repair centres. Unauthorised tampering
can lead to property damage and will void the warranty provided by EPA GmbH.
2.4 Responsibility:
WARNING
Electronic devices are never fail-safe. The installer and/or operator of the machine or
system is responsible for ensuring that the system/machine is restored to a safe state
if the device fails.
The safety requirements for electrical controllers are set out in DIN EN 60204-1; VDE
0113-1 "Safety of machinery" in the section titled "Electrical equipment of machines".
These provisions ensure the safety of persons and machines as well as the
maintenance of the functional capability of the machine or system and must be
observed.

2.5 Connection
WARNING of hazardous electrical voltage
Risk to life from electric shocks! Death or serious injury!
To avoid electric shock, take appropriate precautions.
Follow the accident prevention regulations for electrical systems and equipment when
carrying out all work.
WARNING
The terminals are intended solely for the purpose for which they are defined in the
connection description. These must not be used for any other purpose.
The potential at the terminals can be at the mains voltage level under certain
circumstances. For safety reasons, the connecting cables must therefore have a
corresponding dielectric strength and be sufficiently insulated.
CAUTION
The device must be supplied with the voltage specified in the technical data. Higher
voltages can destroy the device.
Surge voltages between the terminals can destroy the device.
The device must be fixed firmly into place while the power supply is disconnected
and no parts are live.
A fixed, low-impedance connection is required between the PE connection and the
protective earth.
The PECON+
®
may only be operated in TN-S systems (separate neutral and protective
earth throughout the system; grounded star point).

Function
4.1 Operating principle
The PECON+
®
determines the availability of the protective earth of single and 3-phase networks by
measurement.
If the protective earth is available, an internal release relay (potential-free contacts) is actuated. A
separate line contactor can now be switched via the signal contact in order to supply the
consumer(s) with voltage.
4.2 Normal state
When the PECON+
®
is ready for operation, the green LED "OK" on the front cover is illuminated and
the "Betrieb" (“Operation”) signal contact is activated.
For the PECON+
®
NVT and PECON+® NVF models, two internal release relays are activated
(signal contacts “Freigabe-Relais 1” ("Release relay 1") and “Freigabe-Relais 2” ("Release
relay 2").

4.3 Fault
When the protective earth is interrupted, the release relay in the PECON+
®
trips immediately.
The fault is signalled by the red "Alarm" LED in the front cover, and the "Alarm" signal contact is
actuated.

Depending on the model, swapping the phase and neutral can be interpreted as a fault or deemed
acceptable for release.
An additional signal contact for "Reverse polarity L / N" is provided for models PECON+
®
S1 /
S2 / S3 / S4 and PECON+
®
NVT-2 / NVF-2.
The differences between the various models are explained below:
PECON+
®

PECON+
®
S1 and PECON+® S3:
• The device is not ready for operation if the polarity is reversed (interpreted as fault).
• An additional signal contact is actuated if the polarity is reversed.
• The connection option “Ext. Prüftaste” (“Ext. test key”) cannot be used.
PECON+
®
S2 and PECON+® S4:
• The device is ready for operation despite polarity reversal (polarity reversal L / N is tolerated)
• An additional signal contact is actuated if the polarity is reversed.
• The connection option “Ext. Prüftaste“ (“Ext. test key”) cannot be used.
PECON+
®

Network phases fault
This function only applies to the PECON+
®
IT.
All three mains phases must be connected to the device. A neutral connection is not
provided/required. The connection terminals for phases L1, L2 and L3 can be assigned in any phase
relation. The phase relation does not impact the functionality of the PECON+
®
IT.
If a voltage difference between the three phases L1, L2 and L3 of well above 10% is present, the
yellow LED “Fehler Netzphasen” ("Fault mains phase") lights up. The red LED "Alarm" also lights up
and there is no release via the internal relay.
Reset function
CAUTION
The PECON+
®
resets automatically!
If the protective earth is interrupted for a short period and then present again, it is automatically reenabled.
The hysteresis of the response and fallback values prevents possible fluttering of the release relay.
Function test with test key
Proper function of the “Schutzleiterunterbrechung” ("Protective earth interruption") can be checked
manually at any time using the test key on the front cover.

8 Startup / operation
8.1 Switching on
After connecting the supply voltage, the presence of the protective earth (PE) is determined
by measurement. If the required minimum resistance of the protective earth connection is
present, this is indicated by the green LED "OK" and the release is actuated.
Depending on the product version (see section "Function"), a possible swap of the phase
and neutral conductor is also checked. If the phase and neutral are reversed or if the
protective earth is missing, this is signalled via the "Alarm" LED (depending on the product
version) and no release is issued via the relay and/or a signalling contact is actuated.
If the voltage difference of the three phases L1, L2, L3 is >10% in case of the PECON+
®
IT,
no release is issued via the internal relay and a fault is signalled via the red "Alarm" LED.
8.2 Shutdown
To de-energise the device, the voltage supply on the L and N terminals (for PECON+
®
) and
L1, L2 and L3 (for PECON+
