External Power
The apMK12 operates on 12 ~ 32 VDC supply. It can tolerate voltages no
lower than 10 volts and no higher than 35 volts. It draws about 1 ampere
at 12 VDC (with the MX421/B antenna connected). Power wire colors are:
•
Red --------- +12~32 VDC
•
Black ------ Negative Return (-)
Figures 1 and 2 shows the apMK12 rear panel connector and power and
data I/O cable (cable A). Even though the navigator has a reverse polarity
protection device we recommend that the installer observe proper polarity
before hooking up the power leads. Leica also recommends using a 2
Amp. fuse in-line with the red wire as close to the battery as possible.
This not only protects the navigator but also the cabling.
CDU Grounding
Connect the navigator unit to ground to avoid static charge build up. This
can be done in either one of two ways:
1. Connect the Cable A shield to the boat’s
Sea Water Groun
d.
2. Connect the grounding stud of the navigator to the boat’s
Sea Water
Groun
d.
Note
:
‘Sea water ground’ is any electrically conductive material
that is directly in contact with sea water.
