FII M800 SL201/03/02 Copyright TEL2 M800 SL2 Installation2.1 MountingThe M800 SL2 unit is shipped ready assembled for fitting into racks.All that is required is for the connection of suitable cables.2.2 Power SupplyIf a power supply other than an appropriate Tait model is used, ensure that it is capableof providing enough current to drive the T800 system and is also free from excessiveripple or noise.The system should be protected by the use of appropriately rated fuses in the powersupply.Note: It is particularly important when the prime power source is a battery thatfuses be employed in all supply lines.2.3 Reverse Polarity & Overvoltage ProtectionA crowbar diode is fitted to all T854 transmitters exciters for protection against connec-tion to a power supply of incorrect polarity. It also provides overvoltage protectionfrom voltage transients caused by lightning strikes.Note: A fuse must be fitted in the power supply line for the diode to provide effec-tive protection.
