Model SST–2 NEC Class 2 Low Voltage Connections All low voltage wiring shall use 18 AWG or greater stranded conductors with thermoplastic insulation rated for at least 75°C (194°F) at 300 VAC. The temperature sensor is supplied with a 20' (6m) 2-wire jacketed cable lead. The temperature sensor lead may be up to 500' (152.4m) using 18 AWG 2-wire jacketed cable, or up to 2,000' (609.6m) using 12 AWG 2-wire jacketed cable. Temperature Sensor The Temperature Sensor is required for the operation of the SST.

Model SST–2 remains. The ground fault condition will be persistent and will be remembered by the SST even if the unit loses power. To clear the ground fault condition momentarily press the GFEP TEST/RESET switch on the SST. Maintenance The SST–2 does not require routine maintenance.
