Fig. 7 RELAY OUTPUTS WIRING
The outputs 1 and 2 are protected by varistor against
inductive load with inductive component up to 0.5 A.
The contact rating of the OUT 1 is 3A/250V AC resistive
load.
The contact rating of the OUT 2, 3 and 4 is 2A/250V AC
resistive load.
The number of operations is 1 x 10 at specified rating.

NOTES: NOTES: NOTES: NOTES: NOTES:
1) To avoid electrical shock, connect power line at the
end of the wiring procedure.
2 ) For power connections use No 16 AWG or larger wires
rated for at last 75 °C.
3 ) Use copper conductors only.
4 ) Don't run input wires together with power cables.
5 ) Relay output and SSR drive output are both available.
For the relay output selection see "Preliminary
hardware settings" chapter.

NOTES NOTES
1) This output is not isolated. A double or reinforced
isolation between instrument output and power supply
must be assured by the external solid state relay.
2 ) Relay output and SSR drive output are both available.
For the SSR output selection see "Preliminary
hardware settings" chapter.
