Fuses
There is a fuse situated on the DC input version power supply, type 2A time-delay, this can
be replaced by the user. Replacement of fuses should be carried out by qualified service
personnel.
If the fuse should blow again there is probably a problem elsewhere within the unit and the
recorder should be returned for inspection to SIEMENS.
Cables
To fully comply with the requirements of the CE Mark, all cables connected to the rear of
the unit should use screened cable terminated at both ends. A low impedance earth cable
(<50 mΩ) must be connected to the earthing stud on the rear of the recorder, to ensure
that the recorder is always earthed.
Before performing any installation please read the section on
"Warnings and Safety Precautions" on page 3.
All connections to the unit are made via the rear panel, the layout of which is shown in

the recorder case using a low impedance bond. Also avoid use of a length of wire between
the cable screen and the recorder case.
Signal Wiring
Your recorder is intended for panel-mount use, and only the front face is intended to be
exposed to the operator. Disconnection from the supply MUST be made possible by
means of a switch, circuit breaker or other means of supply isolation.
The disconnection device must be included in the panel installation, clearly marked, in
close proximity to the recorder, and within easy reach of the operator. The protective earth
terminal must remain connected (even if the recorder is isolated from the mains supply) if
any of the analogue or relay terminals are connected to hazardous voltage.
