3.8 Replacing the PFU Photo Link Board Fuse

Point

A fuse is used to prevent the power lines between the PFU and the Power Feeders from

shorting. This fuse should be replaced in the following manner.

Fuse types: 045303.5MR (Littelfuse)

CCF1N3.15 (KOA)

Note: The fuses can only be replaced on the newer type of PFUs, which can be identified by the

shape of the lower cover on the Power Feeder connection terminal. This is illustrated in the

figure below.

Procedure

1. Remove the lower cover from the Power Feeder connection terminal.

Note: The photolink board is attached to the cover.

2. Replace the fuse using a pair of tweezers or needle nose pliers. Extract the fuse

carefully to avoid damaging the surrounding holder.
