2.3.1 Fuses
Two fuses S1S1 and S2S2 are built into the 726 Titroprocessor as standard;
both are type 2 ATH (2 A, slow-blow, with high switching capacity, Metrohm
order no. U.600.0107).
Make sure that the instrument is never operated with any different type
of fuse as otherwise there is a fire hazard!
To change blown fuses proceed as follows:
Exchange fuse S1 (zero conductor, 2 ATH)
Remove mains cable from mains connector.
Use a screwdriver to turn fuse holder S1S1 to the left until it can be pulled
out.
Pull out the fuse holder, remove the blown fuse and replace it with a
spare fuse (2 ATH).
Insert the fuse holder in the instrument, press it down with a screwdriver
and then turn it to the right to fix it in position.
Exchange fuse S2 (phase, 2 ATH)
Remove mains cable from mains connector.
Use a screwdriver to push fuse holder S2S2 upwards until it can be pulled
out.
Pull out the fuse holder, remove the blown fuse and replace it with a
spare fuse (2 ATH).
Insert the fuse holder in the instrument and push until it clicks into place.
