The following instructions will assist in the proper installation of Sensata’s RP Series of thermal protectors.
3 Wire RP for Dedicated Voltage
The black lead wire is always connected to the input live wire.
The white wire is the common which is permanently connected at
the factory with an extra six inch piece of wire of the same color.
The third wire of the RP is permanently connected to the live side
of the load.
4 Wire RP for Multi-tap Ballasts
The black lead wire is always connected to the input live wire. The
white wire is the common which is permanently connected at the
factory with all common wires. The red wire of the RP-5A or the
orange wire of the RP-11A is connected to the 120 Volt tap of the
ballast. The yellow wire of the RP-7A or RP-15A is connected to
the 208 Volt tap of the ballast. The orange lead of the RP-18A is
connected to the 277 Volt tap. The blue wire is then connected to
the tap of the ballast which will match the input voltage. Although
the primary usage is 120/277V, the thermal protector inside of
these units is rated up to 480 VAC.
