1. Connection of power supply and ground

Please connect the power supply and the ground (GND) as shown in the figure.

Grounding should be the D class with single earth.

Power supply voltage

DC24 V (DC18 V to DC36 V)

Power consumption

Approx. 0.15 A (at DC24 V)

Warning

●

Connections with voltage outputs should be made securely according to the figures

and also within specified load resistance.
If neglected, it may cause an unexpected failure and/or malfunction to the
instrument.

●

For the connections with voltage outputs, be sure to apply shielded cable, and the

shielded cable should be connected with the F.G. terminal of the instrument. If not
connected, it may cause malfunction due to the effects from external noises and so
on.
