6.4.3. Motor Thermal Protection
l The thermal protection circuit must be installed to prevent the Motor from overheating.
l YS and JS Motors have a built-in thermal sensor. The lead wires of the sensor are connected to the
Motor connector.
l A Cable Set has the outlet lead wires for the protection circuit. Refer to “3.2.3. Cable Set” for
sensor lead wires.
l The protection circuit must be set to turn off the main AC power supply when the sensor is
activated. Refer to Figure 6-8 “Wiring Example” to install the protection circuit that uses 2 lead
wires S1 and S2.
l Thermal sensor specifications
◊ Contact : Normally close
◊ Rating Maximum : 250VAC 3.5A
◊ Rating Minimum : 6V 0.15A
◊ Type : T100R1U1N ( Matsushita Electric )
(Temperature set : 100°C)
◊ Conforms to VDE.
