Protective Fuses and Relays
An instrument fuse is mounted on the back panel.
This is intended to protect the display module and
internal hardware. A hole plug is provided for units
that do not have a display module.

for 0-90VDC motors. This is a re-settable breaker
designed to protect the motor if it becomes over-
loaded. The breaker will have a rating selected to
match the motor on the apparatus.
A lighted fuse holder provides protection for 0-180
VDC motors. A light will come on if the motor be-
comes overloaded and the fuse burns out. The fuse
rating will be selected to match the motor on the
apparatus.
