2.1 Mounting
The 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 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 connec-
tion to a power supply of incorrect polarity. It also provides overvoltage protection
from 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.

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allow the chassis to be fully withdrawn from the guide.

Note: Figure 2.2 above shows the standard pin allocations for the T800-03-0000
auxiliary D-range kit. A T800-03 auxiliary D-range kit is also available for
special applications requiring custom internal wiring.
