Notwithstanding HIMA standard, other cable colors can be used for wiring due to national
standard requirements. In such a case, please document and verify the deviations.
Connecting the Operating Voltage
Connect the operating voltage supply lines to the clamp terminal blocks (L1+, L2+, L1-, L2-
).
Attach the operating voltage supply lines of the system fan to the screw terminal connector
blocks.
When tightening the screw, make sure that the maximum locked torque specified in Table
45 is not exceeded to ensure compliace with the UL requirements.
Connecting Field Devices and Shielding
With I/O modules, either attach the supply lines for the field devices to the screw terminal
connector block of the connector boards or of the FTA. In doing so, observe the locked
torque of the screws specified in Table 45 to comply with the UL requirements.

Requirements
To connect the field devices via FTAs, use the system cables intended for this use. Use the
system cables to connect the FTAs and the corresponding connector boards.

The correct wiring depends on the application. Observe the following points when laying the
wires:
ƒ Correct wiring
ƒ Cable/line bending radius
ƒ Strain relief
ƒ Cable/line load capacity
Connecting the Base Plates
To establish a - redundant - connection between the system busses of two base
plates
1. Plug a RJ-45 connector of a patch cable in to the UP socket located on the connector
board of the left system bus module within the first base plate.
2. Plug the second RJ-45 connector of the same patch cable in to the DOWN socket
located on the connector board of the left system bus module within the second base
plate.
