4. Exchanging Fuses
In case there is a need for fuse replacement such as a power surge, observe the following
steps to replace the fuse. If the new fuse gets burned again, please unplug the RTCA
Analyzer power and contact your local ACEA representative.
e RTCA Analyzer is equipped with 2-pole fusing. Prior to servicing fuses, ensure that
the power switch is in the o “O” position and disconnect the incoming AC power cord.
Replace fuses only with the type and rating shown on the Power/Fuse label on the rear
panel of the RTCA Analyzer.
Take care to use only Type FSF 5 × 20 fast acting fuses with a 250V, 2A rating. Failure
to do so may result in the potential risk of re and/or personal injury.
Using a small, fl at screwdriver, depress the snaps on both sides of the fuse drawer.
