Mortal danger - Hazardous voltage
•
Electrical equipment operation means that some parts accessible on the outside of the device can be
under high voltage. Therefore all parts under voltage must be covered during operation! This basically
applies to all models, except for the 10 V and 60 V models according to SELV.
•
The DC terminal is isolated from the AC input and not connected to ground internally. Hence there can
be dangerous potential between the DC poles and PE, for instance caused by a connected external
source application. Due to charged capacitors this could even be true if the DC output or the device
are already switched off.
•
Do not insert any object, particularly metallic, through the ventilator slots!
•
For every reconfiguration on the AC or DC connectors, specifically those which can have a dangerous
voltage potential, the device must be cut completely from the AC supply (main switch on the distant
end of the AC cable); it doesn’t suffice to only use the power switch on the front
•
Always follow 5 safety rules when working with electric devices:
•
Disconnect completely
•
Secure against reconnection
•
Verify that the system is dead
•
Carry out earthing and short-circuiting
•
Provide protection from adjacent live parts
•
Avoid any use of liquids near the equipment. Protect the device from wet, damp and condensation.
•
Do not connect external power sources with reversed polarity to the DC terminal! The equipment will be
damaged, even when completely powered off.
•
Never connect external power sources to the DC terminal that can generate a higher voltage than the
rated voltage of the device!
•
Never insert a network cable which is connected to Ethernet or its components into the master-slave
sockets on the rear side of the device!
•
The equipment must only be used as intended
•
The equipment is only approved for use within the connection limits stated on the product label.
•
ESD regulations must be applied when plugging interface cards or modules into the relative slot
•
Interface cards or modules may only be attached or removed after the device is switched off. It’s not
necessary to open the device.
•
Always configure the various protecting features against overcurrent, overvoltage etc. for sensitive loads
to what the target application requires!
•
When operating the device as electronic load: always make sure that the energy recovery can feed back
the inverted energy and that it does not switch to isolated operation. For situations of isolated operation
a supervision device (grid protection) has to be installed
•
It’s not allowed to run the device on AC sources such as generators or UPS equipment. It must only be
connected to a power grid!
•
When controlling the device manually on the HMI while it’s connected to any controlling unit (PLC, PC
etc.) via any analog or digital interface, that controlling unit could take over remote control anytime; for
safety reasons it’s recommended to block remote control by activating the so-called local mode (also
