Monitor connection notes:
• Each monitor should have its own dedicated power cable.
• Equipment which is susceptible to noise (such as VHF radios) should not be
wired to the same distribution panel as the monitors. If in doubt the monitors
(or affected equipment) can be wired directly back to the battery/power
source via a dedicated breaker.
Refer to the separate monitor documentation for more details.
