ELECTION
The CT-100B provides auto-ranging power supplies, which automatically sense the line power
value and set themselves accordingly. Ensure that the fuse is correctly rated for the selected line
voltage (the CT-100B is factory configured with a 10 A/115 V fuse). The fuse is located in fuse-
holder F1 on the rear panel of the chassis. The correct fuse ratings are:
115 V operation
10 A slow blow
220 V operation
5 A slow blow
See Figure 2-1 for the location of the line fuse.
CAUTION
Do not attempt to change the fuse with the line cord connected. Ensure that power is off
and that the unit is unplugged before changing the fuse.

ACKPLANE
The CT-100B has a jumper-less auto-configurable backplane using active-automatic daisy
chaining for the VME Interrupt acknowledge and bus grant daisy chain signal lines. This
eliminates the need to manually configure the backplane.
