Ref.: ILL DCS OFF-AIR REPEATERS / ILL PCS OFF-AIR REPEATERS
WARNING:
Before installing the equipment, carefully read the safety norms herewith attached.
A correct repeater installation and setting procedure requires a good knowledge and experience in
installing telecommunication equipment. These activities should be performed by skilled personnel
only. Remember that if the equipment is not installed correctly, it may:
- put the donor BTS temporary out of service,
- be damaged by excessively high input or output signal levels.
4.1) INSTALLATION
1. INITIAL CHECK
Make sure that the supply is complete and/or that the material has not been damaged during transport.
The list of the materials that make up the equipment is described in the relative PACKING LIST.
Should any parts be missing, or should some be damaged, kindly inform the Sales Dept. of RFS
immediately, in order to facilitate replacing and/or repairing the parts involved.
WARNING:
Before installing the equipment, always make sure that the repeater is not powered up:
- Check that both ON/OFF switches located inside the alternate current powered repeater are
in the OFF position (AC voltage circuit breaker, ref. 59 and 48Vdc circuit breaker, ref. 22
FIGURE 1a).
- Check that the ON/OFF switch (48Vdc circuit breaker, ref. 22, FIGURE 1b) located inside the
direct current powered repeater is in the OFF position.
The LEDs inside the repeater must be turned off.
