Below are some importanttips to remember when installing your newequipment.• Pre-test the equipment before installation.• Consult National Electrical Code and localcodes before installation.Installation InstructionsUnpacking the EquipmentTo protect your new scoreboard system fromaccidental damage, follow the steps below: Carefully remove all equipment from itspacking carton. Do not pry against thescoreboard in any way. Inspect for damage.Note: If damage to any equipment contactcarrier immediately.There is an electronic module located insideeach shot clock. Consult the includeddrawings for the exact location and accessmethod.Make sure all plugs are firmly seated in theirproper sockets. If some cables are loose ordisconnected, refer to Module Illustration.This print identifies the function of eachmodule plug and shows where to connect thecables.Pre-Test Your Equipment(SCD-T5 Pre-Mounting Test)Connect a length of 2-WIRE cable from theBNC connector on the end of the moduleinside the shot clock to your signal source.(control or receiver) (See installation printfor module location)Connect the shot clock to a temporary powerservice. (See installation print for powerservice requirements.)Follow the Control Hookup & Testing Guideto make sure the system operates properlybefore installing the scoreboard.Scoreboard MountingThe installation print shows the mounting centersand location of power. The mounting bracketshave a slot 1 ½ in. by ½ in. wide.Secure at all mounting brackets provided.The shot clocks are equipped with a splice boxfor use with conduit.Always use good mechanical practices whenmounting the shot clocks:• Use a flat washer and lock washer with aminimum 3/8” bolt to prevent vibration fromloosening the fastening device.• Use only plated fastening devices to preventrust or corrosion.Power Service ConnectionsThe power service for each shot clock is 120V,1A, 50/60HZ. This allows a 20 per cent safetyfactor to eliminate nuisance tripping of thecircuit breaker. To eliminate service problems atsome future date and the possibility ofoverloading the circuit breaker, we suggestinstalling a dedicated service or circuit for theshot clocks. The contractor or installationpersonnel will determine length and size of thewire to maintain the voltage needed to supportthe circuit load. We recommend the powerservice maintain 120V at the shot clock undermaximum load.If conditions permit, the owner may place thepower service and the 2-WIRE control cable inthe same conduit. The 2-WIRE cable has adielectric strength of 300 volts or better. Consultthe National Electrical Code and local codes forthe installation of Class 2 wiring.
