Installation
3 PCS and PCS2 Power Current Sensors
Installation
The PCS requires +12 VDC (+11 VDC to +17 VDC @ 20 mA minimum) for operation; the PCS2
is simply plugged into a 120 VAC three-hole wall outlet to obtain power.
PCS and PCS2 Installation
1. Provide +12 VDC power from the Central Controller or external power supply, and connect it
to the port on the PCS. Refer to the Wiring Guidelines section on page 3 for more information.
2. Connect the STBY and ON outputs to the appropriate system inputs. Refer to the Wiring
Guidelines section on page 3 for more detailed information.
3. Plug the unit into the PCS AC receptacle. The term unit refers to the piece of equipment the
PCS or PCS2 is sensing for power status.
4. Plug the PCS into an AC outlet.
Rack mounting the PCS2
To rack mount the PCS2 using the optional AC-RK Accessory Rack Kit:
1. Remove any connected power and communication connectors from the rear panel.
2. Remove the two screws on the front panel of the PCS2.
3. Remove the front panel and the space bracket behind the panel.
4. Remove the rubber feet on the bottom of the unit, if necessary. Insert a scissors blade or other
sharp object into the side of one of the rubber feet and pull it off. Do the same to remove the
other three rubber feet.
5. Place the unit in the appropriate opening in the AC-RK.
6. Place the front panel of the PCS2 on the front of the rack over the unit and secure the front
panel using the two screws removed in step 2.
Wiring Guidelines
The Wiring Specifications table lists wire sizes and the maximum lengths allowable between the
PCS/PCS2 and the Central Controller. The maximum wiring lengths are based on a minimum of
13.5 volts available at the power supply output. The PCS/PCS2 requires a local +12 VDC power to
operate properly. The maximum wiring distance between the power supply and PCS/PCS2 units are
determined by power consumption, supplied voltage, and the wire gauge used for the cable.
To reduce the possible effects of ground loop noise in the video, use a single-source power supply
mounted within distances specified in the following table.
