All that is required is for the connection of suitable cables. 2.2 Power Supply If a power supply other than an appropriate Tait model is used, ensure that it is capable of providing enough current to drive the T800 system and is also free from excessive ripple or noise. The system should be protected by the use of appropriately rated fuses in the power supply. Note: It is particularly important when the prime power source is a battery that fuses be employed in all supply lines. 2.3 Reverse Polarity & Overvoltage Protection A crowbar diode is fitted to all T854 transmitters exciters for protection against connection to a power supply of incorrect polarity. It also provides overvoltage protection from voltage transients caused by lightning strikes. Note: 01/03/02 A fuse must be fitted in the power supply line for the diode to provide effective protection. Copyright TEL FIII M800 SL2 2.4 Wiring The D-range input and output connections are shown in Figure 2.1 and Figure 2.2. Ensure that the cables are not subjected to any stresses due to tight bends or incorrect lengths. Make sure the RF coax cable to the N-type connector is free from sharp bends or twists. If access to the rear of the rack frame is restricted, the cable should be long enough to allow the chassis to be fully withdrawn from the guide.
