1.2 Warnings and safety
General safety guidelines
DANGER!
Incorrect use
Unjustified removal of protection devices, incorrect use, faulty installation or inappropriate operation could represent a
serious risk to personnel and equipment.
All work relating to transportation, installation, commissioning and maintenance must be performed by experienced,
qualified personnel (see IEC 364, CENELEC HD 384 or DIN VDE 0100, as well as national specifications for installation
and accident prevention).
In these basic safety instructions, qualified personnel means persons competent to install, mount, commission and operate the
product and possessing the relevant qualifications.
Safety guidelines during installation
The installation and cooling of equipment must comply with the specifications in the data sheet.
The MIB must be protected against excessive stress. In particular, there must be no damage to parts and/or modification of the
clearance between components during transportation and handling.
Avoid touching any live parts.
Safety guidelines during electrical connection
When work is performed on MIBs which are powered up, national accident prevention specifications must be respected.
The electrical installation must comply with the relevant specifications (for example conductor cross-sections, protection via fused
circuit-breaker, or/and connection of protective conductor).
Protective earth
DANGER!
Risk of electric shock
Failure to connect the earth/ground may result in electric shock.
The MIB must be connected to an approved earth/ground using the earth/ground terminal.
Electrostatic discharge
Protect the equipment terminals from electrostatic discharge when not installed in a grounded rack. Electrostatic discharge can
damage the terminals.
