GEN ERAL
38 Before starting electrical connection observe the following:
WARNING
EN SURE THAT ALL POWER SUP PLIES ARE ISO LATED BE FORE ANY
ELEC TRI CAL CON NEC TION TAKES PLACE.
39 Isolate power supplies as follows:
(1) Ensure that the associated display is turned off.
(2) Remove fuses from mains isolators.
40 The casing of the upmast transceiver must be securely earthed to the platform with
braided copper wire.
41 Allow sufficient length on all cables to allow for routing through the transceiver. Make
sure that there is sufficient slack to allow for extreme movements during sudden shock to
the vessel.
42 Ensure that all cables are secured to their associated entry point and that screened cables
are earthed to their respected units.
43 Fit cable through gland in accordance with the diagram shown on Figure 9.
COVER RE MOVAL
44 Before any electrical connections can be made, covers have to be removed from the
following equipment:
(1) Upmast Transceiver.
(2) Drive Control Unit.
(3) Optional Mains Isolator.
Upmast Trans ceiver (DTX-A3)
45 Using a 12 mm spanner, release the seven bolts securing the side cover to the Upmast
Transceiver and remove the cover. Note that the cover is attached to the enclosure by a
strap to prevent it from being dropped. Cable routing is shown in Figure 7.
Drive Con trol Unit (GTX-A24)
46 Remove the Drive Control Unit cover by releasing the four fixing screws. Cable routing
is shown in Figure 8.
Op tional Mains Iso la tor (80-261-600)
47 Open the Mains Isolator cover by releasing the captive screw.
