power cables
j fitted with the supplied power connector f (as shown in

age for the CTU is 32VDC. Use either a PMU 12VDC or
24VDC auxiliary output, or an external power supply.
Note that the auxiliary output can be supplied to the CTU
via the system interface connector on the reciter if the aux-
iliary DC power cable is fitted, as well as via a direct con-
nection to the PMU auxiliary output.
