Warning
Before switching on this instrument and before connecting any other cable,
the protective earth terminals of this instrument must be connected to the
protective ground conductor of the (mains) power cord. The mains plug
shall only be inserted in a socket outlet provided with a protective earth
contact. The protective action must not be negated by use of an extension
cord (power cable) without a protective conductor (grounding).
Make sure that only fuses with the required rated current, as marked on
the ASMi-450 rear panel, are used for replacement. The use of repaired
fuses and the short-circuiting of fuse holders is forbidden. Whenever it is
likely that the protection offered by fuses has been impaired, the instrument
must be made inoperative and be secured against any unintended
operation.
Power Connection Before starting, check that the ON/OFF switch on the ASMi-450 rear panel is
set to OFF.
AC Power Connection
Skip this section if the ASMi-450 is powered from a DC source.
AC power should be supplied to the ASMi-450 through the 5 feet (1.5m)
standard power cable terminated by a standard 3-prong plug.
First, connect the power cable to the connector on the ASMi-450 rear panel, and
then to the mains outlet.
DC Power Connection
Skip this section if the ASMi-450 is powered from an AC source.
Connect the power cable to the DC power connector, and then connect the other
end to the DC distribution panel. Pay attention to correct polarity.
