Rack mounting
one AC 3
Secure the rack mount “ears”
 (supplied with the optional
GA 3 rack adapter) to the AC 3 in the same way as described
for the stacking elements (see page 7).
Secure the blanking plate
 to one of the rack mount
“ears”
 using two recessed head screws (M 6x10)
(see diagram on page 10).
Insert the two blanking plugs
 into the holes of the blan-
king plate (see diagram on page 10).
CAUTION!
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.
