NOTES:
Do not use the unoccupied terminals and ports for other purposes.
•
In order to prevent miswiring, label both ends of each cable with the unit and terminal names to which they are to be connected.
•
For connecting other manufacture’s products, refer to the instruction manuals for those products.
•
The illustration of the unit’s rear panel differs from the actual one. This is for simplifying the connection diagram.
