, class 2 reinforced insulation from the
instrument.
Basic insulation between the relays.
UL speci cations for connections:
Use copper wires approved for a temperature of 75 C.
Minimum cross-section AWG 22-14 rigid or exible.
To tighten the terminals, apply a torque of 7 Lb/In for the black terminals (SAURO)
To use the instrument in compliance with UL-873, a load with a maximum voltage 24 Vac, class 2, can be
connected to the relay output.
Tab. 5.b
Warning: All the connections, except for the relays, must be
connected to very low voltage circuits with reinforced insulation.
