NOTES:

1)

Before connecting the power line, check that

 

the voltage is correct (see Model Number).

2)

For supply connections use 16 AWG or larger

 

wires rated for at least 75 °C.

 

3)

Use copper conductors only.

 

4)

Do not run input wires with power cables.

5)

Polarity does not matter for 24 Vdc wiring.

6)

The power supply input is NOT fuse protected.

 

Please provide

it externally.

When fuse is damaged, it is advisable to verify

 

the power supply circuit, so that it is necessary to

 

send back the instrument to your supplier.

7)

Safety requirements for permanently

 

 

connected equipment:

 

 

- Include a switch or circuit-breaker in the installation.

- Place the switch in close proximity to the equipment and within easy reach of the operator.

- Mark the switch as the disconnecting device for the equipment.

NOTE: A single switch or circuit-breaker can drive more than one instrument.

8)When the NEUTRAL line is present, connect it to terminal 4.

9)To avoid shock and possible instrument damage, connect power last.
