A60 Installation Manual
Use commonly practiced methods to determine proper wire gauge based on wire
length, current, and wire tables. You may also trim the power cable supplied with
the A60 to reduce overall wire length. Only use enough wire to connect the unit to
the power source, including a service loop.
Note:
When the A60 has been powered off using the PWR key but is still electrically con-
nected to the power supply, the GPS continues to draw current.
The supplied power cable has a cross section of 10 mm.
CAUTION: Correct Polarity
If the power connections are accidentally reversed the system
will not work. Use a multimeter to ensure that the input power
leads are connected for correct polarity.
NMEA Cable (R08004)
The 5-pin, 1.5m (5 ft) NMEA input cable is supplied with exposed wire connecting
tails. These should be connected to your existing NMEA instruments using
suitable connector blocks as follows:
GPS Cable
