ELECTRICAL INSTALLATIONWe recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the locker room clock. These connections include connecting the locker room clock to a power source, installing the ScoreLink 200 or the control cable, and connecting the control console. Power Connection The locker room clock requires 120 VAC service at the locker room clock to operate properly. Maximum power consumption of Model 2106: 40 Watts. The locker room clock has a 6 ft. attached power cord located at the top of the cabinet. Plug the power cord into a grounded NEMA 5-15R receptacle. The receptacle should be controlled by a separate circuit breaker so that the locker room clock can be turned off without turning off other electrical devices in the facility. Figure 1 shows the electrical connection points on the locker room clock.
The control cable connects the locker room clock to the control console. A small junction box with a ¼” stereo jack mounted on the face plate is attached to the control cable at the point of operation of the locker room clock. This junction box should be securely mounted within ten feet of the rear of the control console. Most customers order the control cable with the junction box attached. Some customers prefer to attach the junction box after the cable is installed. Those customers must solder the control cable to the ¼” stereo jack. Figure 2 shows the control cable wire connection points on the rear of the ¼” stereo jack.
A ¼” stereo plug is attached to the locker room clock end of the control cable. It is inserted into the serial data input jack mounted on top of the locker room clock. Most customers order the control cable with the ¼” stereo plug attached. Some customers prefer to attach it after the cable is installed. Those customers must solder the ¼” stereo plug to the cable according to the figure 3. Unscrew the stereo plug cover from the plug body to expose the contact pins.
If the customer is operating a scoreboard with the same control console as the locker room clock, he can install the control cable from the ¼” stereo jack mounted on the top of the locker room clock to either the shot timer jack located on the right side of the scoreboard (serial data output jack located on the top of models 2350-4, 2650-4, and 2655-4) or to the control console. When connecting between the shot timer jack of the scoreboard to the model 2106 locker room clock, each end of the control cable has a ¼” stereo plug attached. Additional scoreboards and shot timers can be controlled by connecting a control cable from the serial data output ¼” stereo jack on the locker room clock to the serial data input ¼” stereo jack on the top of the additional scoreboard or shot timers. Attach ¼” stereo plugs on each end of these cables according to figure 3.
Control Console Connections The 10 ft. extension cable has two molded ¼” stereo plugs attached to it. It is used to connect the control console to the junction box or ScoreLink 200 Transmitter. The following steps describe how to connect the control console:
Control Console Safety Warning This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a qualified electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-type plug.
