Mounting the AC 3 into a 19" rack
Risks when rack mounting the device!
When installing the device in a closed or multi-rack assembly,
please consider that, during operation, the ambient tempera-
ture, the mechanical loading and the electrical potentials will be
different from those of devices which are not mounted into a
rack.
The ambient temperature within the rack must not exceed
the temperature limit specified in the specifications.
Ensure sufficient ventilation; if necessary, provide additional
ventilation.
Make sure that the mechanical loading of the rack is even.
When connecting to the power supply, observe the informa-
tion indicated on the NT 3-1 table top power supply. Avoid
circuit overloading. If necessary, provide overcurrent protec-
tion.
When rack mounting, please note that intrinsically harmless
leakage currents of the individual power supplies may accu-
mulate, thereby exceeding the allowable limit value. As a
remedy, ground the rack via an additional ground connec-
tion.
