Electric shock Hazard

1) Before connecting the instrument to the supply,

make sure that the line voltage corresponds to

that indicated on the rating plate.

2) To avoid electric shock, connect the power line at

the end of the wiring procedure.

3) For supply connections use No 16 AWG or larger

wires rated for at least 75°C.

4) Use copper conductors only.

5) Do not run input wires together with power line

cables.

6) For 24 V AC/DC the polarity does not matter.

7) The power supply input has NO fuse protection.

Please, provide a T type 1A, 250 V fuse externally.

8) The safety regulations for equipment

permanently connected to the mains require

that there is a switch or circuit breaker in the

building electrical system and that this:

- is near the device and can easily be reached by

the operator;

- is marked as the device ON/OFF .

NOTENOTE

NOTE: A single switch or circuit-breaker can drive

more than one instrument.
