* For maximum extension cable length please consult your local Renishaw representative.
IM PORTANT: The shield should be connected to the machine Earth (Field Ground).
IMPORTANT: If the flying lead variant is used or the connector is modified or replaced, the customer must
ensure that both 0 V cores (White and Green) are connected to 0 V. In such situations, care should also
be taken to ensure that 0 V and Earth remain properly insulated from each other throughout the cable run.
