Safety
CAUTION
Danger from unexpected movement.
• Check within the framework of your EMERGENCY OFF concept to ascertain the
measures necessary for putting your machine/system into a safe state in the
event of an EMERGENCY OFF (e.g. switching off the operating voltage, shutting
off pressure).
NOTICE
Interference from cables that are too long.
Long cables reduce the immunity to interference.
• Keep within the maximum permissible cable length of 30 m.
NOTICE
Mechanical destruction of the electronics.
Angled connectors may direct strong forces into the product.
• When using angled connectors pay particular attention to ensure that excessive
force is not exerted on the connections. Install cables so the forces on the
product connections are kept to a minimum.
NOTICE
Avoiding malfunctions from electromagnetic interference.
• Unshielded cables up to 30 m in length can be used for the Actuators and
Buffer connections.
• Only use shielded cables and push-in connectors for all other connections.
• Use equipotential bonding when connecting components with shielded cables.
The cable shields and shield connections of the product are not designed to
carry compensating currents due to potential differences.
• Use cables that are as short as possible with a large cross-section.
• Connect the ground connection FE and also the cable shields to the earth
potential with low impedance.
• Use an earth strap with a suitable cross-section on the earth connection FE on
the front plate.
NOTICE
Damage to the product due to excess voltage when switching on.
• Only use round cables and no single cores for the supply connection.
• Pay attention to the lower inductance of the supply cable to prevent voltage
overshoots when connecting to low impedance supplies.
• For optimal damping of excess voltage, the resistance of the supply cable
should not be too low.
Recommendation: cross-section 1.0 mm
2
or 1.5 mm

• Observe the maximum load capacity of the cable.
• Use suitable fuses for the supply cable and do not exceed the datasheet values.
Only use regulated power supply units. First establish the secondary-side con-
nection, then switch on the power supply unit on the primary side. Do not
connect to sources when powered.
NOTICE
Protection of the product and prevention of overload on the GND pins of the
interfaces.
• Do not connect outputs in parallel.
• Do not feed voltage to the outputs; this will override internal current monitors;
if the polarity is reversed, there is a risk that the product will be destroyed.
• Only use the GND connection of the respective plug or the GND of the fixed
power supply as the GND.
• Do not return any of the output signals at the PLC, actuator or buffer plug
connector to the GND of any of the other output plugs.
• The outputs are switched off on overload. This may also affect the "Error" and
"Warning" outputs of the PLC interface. They are only intended for diagnostics.
To identify the operating status use the “Ready for operation” signal that
operates with reverse logic. If a fault occurs, it is switched off. As a result, an
external control system may identify the fault.
• When connecting inductive loads, e.g. solenoid coils, valves, contactors or
relays, provide a suitable quenching element directly on the load.
• Select appropriate plugs and cables as well as suitable cross sections. Do not
overload cables.

To comply with the IP degree of protection for the completely assembled product:
–
Tighten the union nuts of the plugs hand-tight.
–
Seal unused sockets with the protective caps supplied.
6.2
Selecting fixed power supply
WARNING
Risk of injury due to electric shock.
• For the electrical power supply with extra-low voltages, use only PELV circuits
that guarantee a reinforced isolation from the mains network.
• Observe IEC 60204-1/EN 60204-1.
•
Make sure the fixed power supply fulfils the requirements specified in the
product datasheet with reference to voltage, current and power.
•
Consider a sufficient power reserve.
•
Note the power consumption of connected consumers as well as system
expansions.
6.3
Connecting operating voltage
WARNING
Risk of fire
• Protect the supply line with a 4 A fast-acting fuse.
•
Use a cable with a suitable conductor cross-section.
•
Avoid long distances between the fixed power supply and the product.
Long cables reduce the voltage from the fixed power supply.

CAUTION
Material damage caused by movements of the connected actuator technology.
Take the necessary measures for the machine/system to set the system to a safe
state when switching it on and off if:
• the transporting device is moved to its initial position when the power supply is
switched off,
• the transporting device starts automatically controlled by the CHB-C-N after the
start process of the CHB-C-N.
To prevent the transporting device from starting automatically when the operating
voltage is switched on:
• Select the following in the CheckKon software:
