21. Altering the operating voltage and frequency (Reserved for technical staff only)
If the factory preset operating voltage and frequency do not correspond to those in use in your country of operation, you may alter the settings as described in the following paragraphs. Incorrect selection of operating voltage and frequency will seriously compromise the functioning of the projector and will automatically void the warranty..
21.1. Selecting the voltage on the autotransfomer
1) Loosen the 4 screws on the cover of the base of the unit, as shown in the diagram below, using a Philips head screwdriver, thereby removing the cover completely and allowing access to the internal components of the base of the ProSpot 150 LX.
2) Locate the autotransformer on the right of the base. 3) Select a voltage from amongst 100, 115, 208, 230 and 240V by removing cable n° 7 and moving it to the required voltage. To determine which is the correct tap, refer to the sticker located on the autotransformer. Cable number 9 should not be moved under any circumstances.
4) If the operating voltage selected is either 100 or 115V, replace the 3 Amps T fuse (which is suitable for 208/230/245 V operation) with one rated at 5 Amps T. The fuseholder is located in the base of the unit. The operation should be reversed should the voltages be reversed. Replacement fuses of suitable ratings were provided in the packaging of your fixture with this manual.
T 3A @230V T 5A @115V
5) Operating frequency may now be set (if necessary) or the base cover replaced with the four screws previously removed.
