On/Off switch for Quantum radar

[BosSH]

I am installing 2 ES78 MFD's and a Quantum radar. The positive wires from the power cables of all three devices will run to a dedicated positive bus which will be controlled by a single breaker. Additionally, each positive wire will have its own in-line fuse. Is this an acceptable way to wire the radar, or does the power cable to the Quantum radar need its own on/off switch as well; i.e., will the master MFD provide the needed on/off control?

Welcome to the Raymarine Forum BosSH,

Q1: Does the power cable to the Quantum radar need its own on/off switch as well?
A1: Per the FAQ found here, it is recommended that radomes and open array pedestals be powered from a dedicated power circuit which may be switched ON/OFF without affecting the power state of the system's other marine electronics devices. This referenced FAQ also explains the reason behind the recommendation for such a switch.

Chuck,

Per the link you provided, it seems that the dedicated radar power switch is intended mainly to allow troubleshooting of a failed wifi connection between the Quantum and the MFD(s). If the Quantum uses a wired data connection, would you still recommend a dedicated power switch for the Radar?

Thanks.

Welcome to the Raymarine Forum Istream,

Whether interfacing with a Quantum radome via a wired Ethernet connection or via Wi-Fi, it is recommended that Quantum radomes be powered from a dedicated switched power circuit to permit the radome to be restarted without affecting the power state of the system's other marine electronics products.
