6. Thread the connector on finger tight.
7. Insert the other end of the cable (from step 5) into the Receive
SERCOS connector on the 1756-M08SE interface module.
8. Thread the connector on finger tight.
Note: Fiber optic cable lengths of 1.0 m (3.2 ft) to 32 m (105.0 ft) are
available in plastic or glass. Lengths of 50 m (164.2 ft) to 200 m
(656.7 ft) are available in glass only.

This procedure applies to 5 and 10 kW system modules and assumes
that your system does not require an external shunt resistor.
To connect your internal shunt resistor:
1. Verify that there is no 24V control power or 360/480V AC input
power applied to the system.
2. Verify that the jumper is installed between COL and INT in the
shunt power connector plug (refer to Figure 2.10 for the jumper
location).
3. Insert the shunt power connector plug into the shunt power
connector on the bottom of the system module (refer to Figure
2.10 for the connector location).
