User manual SMART DEVICES DIMENSION 3K

[. . . ] If air freight is requested by the dealer, the difference between air and surface charges will be billed to the dealer. This limited warranty does not cover products that have been abused, altered, modified, or operated in other than specified conditions. Prior factory approval is required on all returns. [. . . ] The DIM 3K has no built in circuit breakers or fuses, and you MUST supply a circuit breaking device (in the LINE side) of the proper rating for your load. Remember that for a continuous load, circuit breakers should be run at about 80% of their current rating. To determine your current requirements, divide the total lighting wattage by the line voltage to get the load current. This is the current at the rated line voltage. Since the lights will rarely be run at full line voltage, the actual current will be less in normal operation. For example, a 3000 Watt load at 120VAC pulls about 25 Amperes of current. If you plan to set the HIGH lights level to the full line voltage, your circuit breaker would need to be rated at 30 to 35 Amperes. If you are going to set the HIGH lights levels to around 100VAC, then the normal current will be less, and the breaker could be rated at about 25 Amperes. INSTALLATION Mounting Mount the DIM 3K in a well ventilated location to avoid overheating. Even though the DIM 3K is conservatively rated, excess ambient temperature can add to the normal temperature rise of the product and can possibly lead to premature failure. Do not block airflow around the heatsink area as this will cause excessive temperature rise. Page 3 DIMension 3K The FULL terminal is used to place the dimmer instantly in the full brightness mode. This is useful for emergency situations such as a fire alarm. This terminal requires a latching connection to the COM terminal. As long as the connection is closed between the FULL and COM terminals, the lights will stay at full brightness regardless of the condition of the other terminals. Adjustment The dimmer has three light levels which must be adjusted for each individual theatre. [. . . ] Alternatively, pushbutton switches could be used for manual selection of light levels. The relays or switch contacts must be isolated with no external voltages applied to them. The application of external voltages to the dimmer control terminals may result in damage to the dimmer.
