Wiring Connections
The following chapter primarily
assumes a DCU panel.
If installing an RP, then just disregard
descriptions that is not described in
the table
“Connector Pinout RP
210E/220E
”.
General
To protect against EMC noise, we
recommend that all cables are
shielded.
Note! The shield of all cables shall be
connected to ground/hull,
not
to 0V!
For good electrical noise separation,
consider routing some cables separate
from other cables
–
for instance the
pickup signal cable.
Note! Connect shield in one end of the
cable only.
Grounding
In marine installations, ground and 0V
volt should not be connected together.
In a ship installation, the hull is the
“ground” whilst the battery minus
is
the 0V.
In the DCU system, +12/24V and 0V
are filtered to ground using special
filter components. This is done to
reduce electrical noise entering the
system.
Note! Please keep ground and 0V
separated!
If ground and 0V is connected, these
filters do not work properly.
Power Supply [C1P 11
–
C 1P12]
The 200E Series is designed to run on
either 12 VDC or 24 VDC supply
voltage.
Note! Make sure the supply power is
sourced directly from the battery, and
not
from the starter engine, as the
voltage drop over the latter is
significant.
Power Supply Requirements
The panel must be sourced with an 8-
32VDC supply. This is the “full
functionality” range.
General
Use a cable with twisted pair wires to
minimize the effect of noise on the
supply input.
Connect the cable straight from the
battery and keep the cable as short as
possible.
Use at least 1.0mm
2
(17 AWG) wires
for the power supply.
12 V supply
If the supply voltage is in the range 8-
16V, then the panel automatically
assumes it is on a 12 VDC system.
24 V supply
If the supply voltage is in the range
16-32 V, then the panel automatically
assumes it is on a 24 VDC system.
Alarm for Low Power Supply
The input voltage is monitored with
fixed set points. The set points are as
follows:
