Safety notices
Mortal danger - Hazardous voltage
•
Electrical equipment operation means that some parts can be under dangerous voltage.
Therefore all parts under voltage must be covered! This basically applies to all models,
though 60 V models according to SELV can’t generate hazardous DC voltage.
•
All work on connections must be carried out under zero voltage (output not connected to
load) and may only be performed by qualified and informed persons. Improper actions
can cause fatal injury as well as serious material damage.
•
Never touch cables or connectors directly after unplugging from mains supply as the
danger of electric shock remains!
•
Never touch the contacts on the DC output terminal directly after switching off the DC
output, because there still can dangerous voltage present, sinking more or less slowly
depending on the load! There also can be dangerous potential between negative DC
output to PE or positive DC output to PE due to charged X capacitors which may not
discharge.
•
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
•
The equipment must only be used as intended
•
The equipment is only approved for use within the connection limits stated on the product label.
•
Do not insert any object, particularly metallic, through the ventilator slots
•
Avoid any use of liquids near the equipment. Protect the device from wet, damp and conden
-
sation.
•
Do not connect loads, particularly such with low resistance, to the device while the DC output is
switched on; sparking may occur which can cause burns as well as damage to the equipment
and to the load.
•
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.
•
Do not connect external power sources with reversed polarity to the DC output! The equipment
will be damaged, even when not powered.
•
Avoid where possible connecting external power sources to the DC output, and never those
that can generate a higher voltage than the nominal voltage of the device.
•
Never insert a network cable which is connected to Ethernet or its components into the mas
-
ter-slave socket on the back side of the device!
•
Always configure the various protecting features against overvoltage etc. for sensitive loads to
what the target application requires!
