General notes
WARNING!
Danger due to electric current!
Device and environment in the switch cabinet may carry lethal voltages.
Before carrying out any work, make sure that the device and environment
are disconnected from the power supply.
Observe the relevant safety regulations when handling live devices.
Ensure that only qualified personnel mount and install this module.
CAUTION!
Temperature rise of external lines!
The heat dissipation of the system can raise the temperature of external lines.
Only use thermally suitable connecting cables. The temperature specifica-
tion must be 5 °C above the ambient temperature!
NOTICE
Destruction of the bus node by the compensating currents
Potential differences between grounding points may cause compensating cur-
rent in the shield connected on both sides.
Eliminate this situation by means of lines for equipotential bonding.
NOTE
Separate the insulation areas!
The Cube20S is specified for the SELV/PELV environment. The devices con-
nected to the system must be specified for the SELV/PELV environment.
Install cables of devices which do not correspond to the SELV/PELV envi-
ronment separately from the SELV/PELV environment!
NOTE
Conditions for UL compliant operation:
Use only SELV / PELV power supplies for power.
The Cube20S system may only be installed and operated in a housing in
accordance with IEC 61010-19.3.2 c).
