The two relay output must be interlocked (see chapter
"Preliminary hardware setting" paragraph "Out 3 and 4
selection").

NOTES

NOTES:
1) Before connecting the instrument to the power line, make sure

that line voltage and the load current are in accordance with the
contact rating (3A/250V AC on resistive load).

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

wiring procedure.

3) For servomotor connections use No 16 AWG or larger wires rated

for at last 75 °C.

4) Use copper conductors only.
5) Don’t run input wires together with power cables.
6) For feedback potentiometer, use shielded cable with the shield

connected to the earth at one point only.

7) The relay outputs are protected by varistor against inductive

load with inductive component up to 0.5 A.
