2.5 INSTALLATION AT THE RACK IN THE SHELTER
2.5.1 General
This chapter describes the connections at the transmitter and ASU rack: power supply, RF connecĆ
tions, interface connections and connection of a Remote Control (RMMC).
NOTE: For the Thales ATM shelter delivered with the navaids systemall fuses are preinstalled.
If the shelter is provided by the customer, he will be responsible for the installation includĆ
ing a mains fuse box with arrester and a battery fuse box. Following fuse protection is
recommended: external mains fuse for transmitter cabinet F= C20A, for battery fuse
F1= K50A (power) and F2= G0.2A (sensor lines), regard also Fig. 2-6.
For a mains voltage of 115 VAC the standard mains wiring concept allows up to 3 ACC
modules. For a 115 VAC supply with 4 modules provided, standard mains wiring has to
be adapted concerning diameter of supply cables, size of mains terminals and mains filter.
