checked.
2. Ensure that there are no shorts to earth on any of the cables,

The 0V Continuity Check is important to prevent damage to the
Remote Units due to incorrect wiring.
DO NOT connect any cables to the Control Panel until
the 0V Continuity Check has been successfully completed
4. Ensure there is a reading of 150Ω between the CAN H and
CAN L cables on each loop. This check ensures the CAN bus
cables are connected to the nearest Remote Unit but does
not determine if the cables are swapped.
