1.1 RR400 (with separate interface)
Warning:
the interface provides a power supply for the sensors which is protected by a fuse
. A fuse holder is
located on the side of the housing. A 200 mA fuse is supplied as standard (plus a replacement fuse). This value is
suitable for most sensors on the market, but
it is up to the installer to check if it is correct for sensors other than
those supplied by CRISARTECH
.
