Connecting the Expansion Cable: Single-ended
For a system with one non-isolated expansion rack (IC200ERM002) and NO
Expansion Transmitter, connect the expansion cable from the serial port on the
VersaMax NIU to the Expansion Receiver as shown below. The maximum cable
length is one meter. Cables cannot be fabricated for this type of installation; cable
IC200CBL600 must be ordered separately. Note: Do not disconnect an expansion
cable while the system is operating. It will cause momentary disruptions in bus
communications.

Power Sources for Single-Ended Expansion Rack Systems
When operating the system in single-ended mode, the power supplies for the main
rack and expansion rack must be fed from the same main power source. The main
rack and expansion racks cannot be switched ON and OFF separately; either both
must be ON or both must be OFF for proper operation.
Power for module operation comes from the Power Supply installed on the
Expansion Receiver Module. If the expansion rack includes any Power Supply
Booster Carrier and additional rack Power Supply, it must be tied to the same
source as the Power Supply on the Expansion Receiver Module.
