Line voltage selection switch (110 VAC or *220 VAC)
*For models 8524 and 8526, the line voltage switch is not usable and does not
allow for 220VAC operation. Do not connect them directly into a 220V line. For
220V operation, please order model 8524-220V or 8526-220V.
Power Requirements
All of the models, except for models 8524 and 8526, can accept 110V or 220V line input. To switch
between the two line voltage inputs:
1. Verify and change the fuse inside the fuse box beneath the AC input receptacle. See fuse
section for reference to the fuse type and rating.
2. Flip the 110V/220V line selection switch in the rear panel of the instrument.
WARNING:
Models 8524 and 8526 are configured for 110 V operation only. These two models are not
configurable via the line switch on the rear panel. Connecting an AC line input of a 8524 and
8526 to a 220V AC source will damage the units. If 220 V operation is desired, order model 8524-
220V or 8526-220V. “-220V” denotes 220 V operation only, reconfiguration to 110 V is not
possible.
