General Information
2500A Series Operation Manual, 34172 Revision C, March 2008
The safety ground is connected directly to the chassis. If a 3-to-2 wire adapter is to be used, be sure
to connect the ground lead from the adapter to earth ground. Failure to do this poses a shock haz-
ard.
DO NOT position the equipment so that it is difficult to remove the AC line cord.

All 2500A Series models have a line fuse holder on the rear panel. The power line fuse is 2A, Slow-
Blow, 250V, Type T. See Figure 1-1 below for the location of the line fuse.
