The Whirlwind ROK2 Remote Outlet Controller allows a 20 Amp single phase 240 VAC or 208 VAC 3 phase circuit to be turned on and off from a conveniently located switch or a programmable dry contact closure. The device is a double gang decora type design that can installed in a 3.5" deep box or combined with outlets in a multigang box located in a ceiling or wall.
A double pole relay makes and breaks both hot legs of a 208- 240 VAC 20 Amp circuit. The relay operates on 24 VDC which is generated internally. The device is activated by closing a single pole dry contact closure connected to the terminal block which completes the low voltage DC circuit through the relay coil. Control circuit current flow is about 70 mA. A green power on LED illuminates when the ROK2 is turned on.
Two gang mounting of the ROK2 requires a 3.5" deep gangable type box or utility box with an extension ring. Multigang installation with outlets requires at least 2.5" depth behind the faceplate and wire entry should not be directly behind the ROK2. The two incoming hot power legs of either 208 VAC 3 phase or 240 VAC single phase power are connected to the line in terminals and the load is connected to the line out terminals. No neutral connection is required and the earth connection is not looped through. Connect the circuit earth to the load connections first and tap off to connect to the ROK2. Connections are screw type and will accept 12 AWG solid or stranded wire. Control wiring of 18 -24 AWG is acceptable and should be sized for the length of the control run.
