Connect the stripped cables (see Figure 17 and Table 10) as shown in
Figure 24.
• Expose the shield of all three cables in order to make a 360-degree con-
nection with the cable clamp (1).
• Connect the (phase) conductors of the supply, brake and motor cables
7
into their respective terminals (2).
• Form the rest of the cable shield of all three cables into "pigtails" and make
a grounding connection with a clamp as shown in Figure 24 (3).
Make the pigtails just long enough to reach and be fixed to the terminal -
not longer.
