The 9500B is operative for line voltages in the
ranges: 100/120/220/240V, 48-63Hz.
To accommodate these ranges, a small voltage
selector block is housed behind the POWER
FUSE drawer.
2.7.5.1 Selection of Operating Line
Voltage
Ensure that the POWER CABLE is
removed.
1. Insert a small screwdriver blade in the
narrow recess beneath the catch under the
fuse drawer; lever gently downwards until
the catch releases. Pull the drawer out to
reveal the grey voltage selector block.
2. Hook a small finger into the block in the
square recess in its base; pull to disengage
its contacts, and remove from the module
cavity.
3. Rotate the voltage selector board until the
desired voltage faces outward.
4. Ensure that the block is upright. Re-insert
the block firmly into its cavity in the
module.
5. Check the fuse if required (see paras 2.7.4),
then insert the fuse drawer into the module
and press until the catch is heard to click
into place.
6. Check that the desired voltage is visible in
the cutout in the fuse drawer.
