Replacing fuses
Before changing a fuse(s), please observe the following:
1.
Unscrew the 6 Torx T10 screws on the bus coupler's front
panel.
See Fig. 16
The fuse for the P24VA supply voltage supplied by the US2 for
the output module's outputs is located on the back of the bus
coupler's front panel:
1.
Replace the heat-coil fuse: (5x20) super fast-acting 8 A, FF8A.
CAUTION
Applied voltage
Danger of injury from electric shocks.
O
Make sure the relevant system component is not under
voltage or pressure before electrically connecting
modules to the valve terminal.
NOTICE
Damage to the cable connection
The front panel is connected to the plug connector via a cable
and to the bus coupler's electronics via 2 multiple plugs.
O
In order to prevent damage to the cable connection, the
front panel should only be removed far enough to
disconnect both the multiple plugs' contacts (the contacts
are quite difficult to remove). This will disconnect and
isolate the cable's plug connection!
