Installing the EM 100 G4 in a rack
CAUTION
Rack mounting poses risks
When installing the device in a closed or multi-rack assembly, please con-
sider that, during operation, the ambient temperature, the mechanical
loading and the electrical potentials will be different from those of devices
which are not mounted into a rack.
Make sure that the ambient temperature within the rack does not ex-
ceed the permissible temperature limit specified in the specifications.
See “EM 100 G4”.
Ensure sufficient ventilation; if necessary, provide additional ventila-
tion.
Make sure that the mechanical loading of the rack is even.
When connecting to the power supply system, observe the information
indicated on the type plate. Avoid circuit overloading. If necessary, pro-
vide overcurrent protection.
When rack mounting, please note that intrinsically harmless leakage
currents of the individual power supply units may accumulate, thereby
exceeding the allowable limit value. As a remedy, ground the rack via
an additional ground connection.
