3)
Orient the card so the desired voltage is readable
at the bottom. Figure 26 shows the orientations for
the four voltage settings and how to replace the
indicator pin in the card for that voltage. Note that
the arrow beside the setting indicates the edge of
the card you will insert first into the power entry
module.
4)
Reinsert the card into the module,
printed side
of the card facing left, toward the IEC power
connector, with the edge listing the desired
voltage first (down).
Gently but firmly press
the card into the module until it is fully seated.
5)
Close the module door as described in Section 2.2.1.3.
2.2.1.3. Closing the Input Power Module
1)
When you have completed changes to the
line voltage and/or fusing, close the module
door, then gently press it down until it is
fully seated and firmly holding the fuse
holder and voltage selector card in place.
2)
Verify that the white indicator pin shows
the desired voltage. Figure 27 shows the
instrument set for 120 V.
3)
You are now ready to connect the unit to the ac power source using the appropriate
power cord (mains lead).
