Datasheet
This device shorts out the output of the alternator. No such device can survive this 100% of the time. The Shield is rated to the automotive ISO 16750-2 Load-Dump Surge specification. All surge protection devices will eventually fail if the surge is extreme enough. If the limits of the shield are exceeded, the status LED will turn RED, and it will need to be replaced. In circumstances like a lightning strike, the Shield may become damaged, stop providing protection and not show a RED LED. This also indicates the Shield needs to be replaced.
For use in 48 volt systems only.
Dimensions: 2 × 0.6 × 2 in 50 x 16 x 50 mm
Waterproof Rated: IP68
Rated to ISO 16750-2 Load Dump Standard
Installation Instructions and Disclaimer:
Both Shield ring terminals should be on the top of the ring terminal stack on the alternator posts. Do not place them under the battery connections.
Connect the ring terminal of the red and black wire to the alternator battery positive post.
Connect the ring terminal of the yellow and black wire to the alternator ground post.
If Shield status LED is GREEN, Shield is connected correctly and will provide protection to the alternator. If Shield status LED is RED, the Shield will no longer provide protection and needs to be replaced.
If a disconnect occurs in the positive or negative cabling in a system where the only voltage information is received over Canbus, The ARCO shield cannot fully protect an alternator. The ARCO Zeus Bluetooth regulator can accommodate this scenario if voltage sensing is connected on the battery harness, and «Battery Voltage Sense Active» is enabled in the configuration.
Note: The Shield is rated to the automotive ISO 16750-2 Load-Dump Surge specification. All surge protection devices will eventually fail if the surge is extreme enough. If the limits of the shield are exceeded, the status LED will turn RED, and it will need to be replaced. In circumstances like a lightning strike, the Shield may become damaged, stop providing protection and not show a RED LED. This also indicates the Shield needs to be replaced.
