The circuit board is protected by a 20mm anti-surge (type T) fuse, the value of which depends on the supply voltage
as shown in the table below.

This option consists of a circuit board, teminal block and suitable wiring inside a long terminal cover at the rear of the
recorder. The board supplies three mutually isolated dc supplies (nominal 25 Volts) each of which is intended to
power a single 0 to 20mA or 4 to 20 mA current loop.
Access to the output wiring and to the fuse is achieved by isolating the recorder from mains power and opening the
terminal cover (after removing its securing screw). The process is fully described below.
Only one channel

Isolate the recorder from the supply voltage.
At the rear of the recorder remove the terminal cover securing screw (figure 1), taking care to retain it for use in
re-assembly.
Open the cover to reveal the circuit board, user connections etc. (figure 2)

The fuse is located as shown in figure 2. User wiring to the terminal block (figures 4 and 5) can be carried out
now, or the terminal cover can be removed for convenience, as described in steps 5 onwards below.
5. Unplug the IEC connector from the rear of the recorder connector panel
6. Remove the cable clamp, retaining the fixings for later re-assembly.
7. Close the terminal cover, and lift it off, as indicated in figure 3.
