User manual RANE VR 2

[. . . ] DATA SHEET / MANUAL VR 2 VOLUME REMOTE Description The VR 2 mounts in a standard US electrical box and can be covered with a Decora plate. It contains a linear taper potentiometer with a single Euroblock screw terminal for each of the pot's three conductors, the Vr terminal, the Vc wiper terminal, and the ground terminal. Connection Turn the power to the unit off until all connections are made. [. . . ] It is important to ensure that the Remote Ports are not subjected to sustained voltages outside the range of 0 to 5 volts DC or high levels of static. Inputs are protected, however, caution is the better part of. . . It is a good idea to install the wiring, connect it to the Remote and then make the final connections at the Remote Port. This pin is current limited, however, excess heat is generated in the 5 volt supply if a short occurs. Never subject the Vr pin to voltages above 5 volts. Remote Mounting The VR 2 remote assembly mounts in a standard U. S. electrical box with a minimum depth of 2. 25" (5. 5 cm). Use the flat head #6 screws supplied with the kit to mount the remote assembly and silk-screened front panel to the electrical box. Install the knob so that the line on the knob is properly aligned with the silk-screening on the front panel of the remote. Install any Decora plate of your choice. For a secured installation, you may wish to leave the knobs off and use a blank Decora plate to cover the remote after adjustment. GND Vc Vr LEVEL 4 2 0 10 6 8 Decora plate cover, not supplied. Wire Types Variations in wire type do not greatly affect the performance of the remote controls. However, a minimum gauge of 22 stranded wire with a flexible jacket is recommended. You may use 3-conductor unshielded remote control signal cable for shorter runs (less than 200 ft. ) or 2-conductor (1 pair) shielded remote control signal cable (use the shield as the GND return) for longer runs (200 to 1000 ft. ). The type of wire required is influenced by your installation and local electrical codes.
