54 Electrical installation
 Connection procedure
1. Remove the terminal cover by simultaneously pushing the recess and sliding the
cover off the frame.
2. Digital signals: Strip the outer insulation of the digital signal cable 360 degrees
and ground the bare shield under the clamp.
3. Connect the conductors of the cable to the appropriate terminals. Use a tightening
torque of 0.4 N·m (3.5 in-lb).
4. For double-shielded cables, twist also the grounding conductors of each pair in
the cable together and connect the bundle to the SCR terminal (terminal 1).
5. Analog signals: Strip the outer insulation of the analog signal cable 360 degrees
and ground the bare shield under the clamp.
6. Connect the conductors to the appropriate terminals. Use a tightening torque of
0.4 N·m (3.5 in-lb).
7. Twist the grounding conductors of each pair in the analog signal cable together
and connect the bundle to the SCR terminal (terminal 1).
8. Secure all cables outside the drive mechanically.
9. Slide the terminal cover back in place.
