3.1. Replacing the Current Input Fuse

To replace the PCON-Y17 mA Input (Auxiliary) fuse, proceed as follows:
- Rotate the fuse holder counterclockwise (see see Fig. 01 for DT Version or Fig. 03 for
Rack Mounting Version – Fuse mA input). Try to use a plastic tool to avoid damaging the
fuse holder;
- The fuse holder will be released;
- Pull the fuse holder and remove the fuse;
- Place the spare fuse (Time-Lag Type Fuse 32 mA / 250 V / 5 x 20mm).

3.2. Replacing the Power Supply Fuse

In case of blow, the 1 Amp fuse (Time Delay Type Fuse 1 A / 250 V / 5x20mm),
placed within the power supply socket on the rear can be replaced.
The fuse may blow due to a voltage spike in the mains or a calibrator component
fault. Replace the fuse once. If a second fuse blows again, it is because the fault is not
that simple. In this case, contact the Presys technical support.
