Rest dangers
Health risks arising from the PacDrive Controller have been reduced by means of
safety technology and design engineering. However a residual risk remains, since the
PacDrive Controller works with electrical voltage and electrical currents.
If activities involve residual risks, a warning instruction is made at the appropriate
points. The note details the potential hazard and its effects and describes preventative
measures to avoid it.
Mounting and handling

Touching electrical parts
DANGER
ELECTRIC SHOCK, FIRE OR EXPLOSION CAUSED BY HIGH VOLTAGE
• Observe the general construction and safety regulations for working on highcurrent electrical systems.
• After installation, check the firm connection of the ground conductor to all elec‐
trical units to ensure that connection complies with the connection diagram.
• Always make sure that the ground conductor is connected when operating elec‐
trical components.
• Before working on electrical equipment with a voltage greater than 50 volts, the
main switch has to be in the "OFF" position and secured, so it cannot be restarted.
• Disconnect devices with a voltage greater than 30 V rms or 42,2 V DC from the
power supply before working on electrical parts.
• Wait at least 5 minutes after switching off before accessing the components.
• Before working on the equipment, discharge the DC bus and use a voltage meter
to make sure that there is no voltage.
• Do not touch the electrical connection points of the components when the device
is switched on.
• Make sure that the drives are at a standstill because potentially fatal voltage can
occur on the motor lines in generator operation.
• Before enabling the device, safely cover the live components to prevent contact.
• Disconnect power connector cables only when the system is deactivated.
• Plug in power connector cables only when the system is deactivated.
• Provide for protection against indirect contact (DIN EN 50178, Section 5.3.2).
• If you are not using prefabricated ELAU cables, check that the assignment of the
new cables complies with the connection diagram of the machine manufacturer.
Failure to follow these instructions will result in death or serious injury.
Dangerous movements
There can be different causes of dangerous movements:
• Missing or faulty homing of the robot mechanics
• Wiring or cabling errors
• Errors in the application program
• Component errors
• Error in the measured value and signal transmitter
• Operation error
Personal safety must be guaranteed by primary equipment monitoring or measures.
Don't just rely on the internal monitoring of the drive components. Monitoring or meas‐
ures should be implemented based on the specific characteristics of the equipment,
in line with a risk and error analysis. This includes the valid safety regulations for the
equipment.
DANGER
DANGEROUS MOVEMENTS
• Prevent entry to a danger zone, e.g. by means protective fencing, mesh guards,
protective covers, or light barriers.
• Ensure the protective devices are properly dimensioned.
• Under no circumstances must the technical safety devices be removed.
• Do not make any modifications to a protective device that may put it out of op‐
eration.
• Protect existing work stations against unauthorized operation.
• Effectively restrict access to the control terminals to allow access only to author‐
ized persons.
• Position EMERGENCY OFF switches so that they are easily accessible and can
be reached quickly.
• Check the functionality of EMERGENCY OFF equipment before start-up and
during maintenance periods.
• Prevent unintentional start-ups by disconnecting the drives from power supply
using the EMERGENCY OFF circuit or using a safe start-up lock out.
• Before accessing the drives or entering the danger zone, safely bring the drives
to a stop.
• While working on the system, power down the electrical equipment using the
main switch and prevent it from being switched back on.
• Secure the system from being switched back on before working on it.
• Avoid operating high-frequency, remote control, and radio devices close to the
system electronics and their feed lines.
• Prior to the initial start-up, check the system and the installation for possible mal‐
functions in all usage scenarios.
• If necessary, carry out a special EMC check of the system.
Failure to follow these instructions will result in death or serious injury
Safe separated extra-low voltage"
PELV Protec‐
tive Extra-Low
Voltage
The signal voltage and control voltage of the PacDriveTM devices are <33 Volts. In this
range, the specification as a PELV system in accordance with IEC 60364-4-41 in‐
cludes a protective measure to guard against direct and indirect contact with danger‐
ous voltage through the safe separation of the primary and secondary sides in the
system/machine. ELAU strongly recommends providing the system/machine with safe
isolation.
DANGER
HIGH ELECTRICAL VOLTAGE DUE TO INCORRECT CONNECTION
• Please ensure that only devices, electrical components or lines that have suffi‐
cient, safe electrical separation from the connected circuits in accordance with
the standards (EN 50178 / 1998 edition - Electronic equipment for use in power
stations) are connected to the signal voltage connectors of this component.
• Ensure that the existing electrical separation is maintained throughout the entire
circuit.
Failure to follow these instructions will result in death or serious injury
FELV Function‐
al Extra-Low
Voltage
When using ELAU Components in systems that do not have safe separation as a
protective measure against direct or indirect contact of dangerous voltages, all con‐
nections and contacts (e.g. PacDrive Controller, Sub-D connector, serial interface) that
do not meet protection class IP2X require a permanent cover. The cover or the device
connection of the connected device must be designed so that it can only be removed
by using a tool. The protective measures have to be adhered on all connected devices
Indicators, control elements, diagnosis
The PacDrive™ System supports the user with its comprehensive diagnostic sys‐
tem.
The diagnostic messages can be read out with the Automation Toolkit EPAS-4 . The
PacDrive™ System contains a powerful message logger in which additional diagnostic
information is recorded.
Diagnostic messages are usually displayed by a control panel on the machine. If an
"error" occurs, read the diagnostic message on this unit and then contact the machine
manufacturer.
Detailed information on diagnosis is available in the Online Help of the Automation
Toolkit EPAS-4.
