1) Before connecting the instrument to the power line, make sure
that line voltage corresponds to the description on the
identification label.
2) To avoid electrical shock, connect power line at the end of the
wiring procedure.
3) For supply connections use AWG 16 or 14 wires rated for at
least 75°C.
4) Use copper conductors only.
5) Don't run input wires together with power cables.
6) For 24 V DC the polarity is a do not care condition.
7) The power supply input is NOT NOT NOT fuse protected. NOT NOT
Please, provide it externally.
Power supply Type Current
24 V AC/DC T 500 mA
100/240 V AC T 125 mA
When fuse is damaged, it is advisable to verify the power
supply circuit, so that it is necessary to send back the instru-
ment to your supplier.
8) The "Safety Requirements for Permanently Connected
Equipment" say:
- a switch or circuit-breaker shall be included in
the building installation;
- it shall be in close proximity to the equipment
and within easy reach of the operator;
- it shall be marked as the disconnecting device for the
equipment.
NOTE NOTE NOTE NOTE NOTE: a single switch or circuit-breaker can drive more
than one instrument.
9) When a neutral line is present, connect it to terminal 1.

An hardware protection for configuration parameters
modification is also available, it is located on the solder side of
the instrument circuit.
The instrument is shipped from factory without any parameter
protection.
In order to enable this protection proceed as follows:
1)Switch off the instrument.
2)Remove the instrument from its case by pushing the locks
(see Fig.8a [A]) and then slip out the instrument until the first
stop (few mm.) (see Fig.8a [B]).
3) Unplug the terminal block cover (see Fig.8b [C]).
4) Slip out the instrument completely (see Fig.8b [D]).
