Connect the stripped cables (see Figure 18 [➙ 33] and Table [➙ 33]17) as
shown in Figure 25 [➙ 33].
• Expose the shield of all three cables in order to make a 360-degree
connection with the cable clamp (1).
• Connect the (phase) conductors of the supply and motor cables 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 25 [➙ 33] (3). Make the
pigtails just long enough to reach and be attached to the terminal - not longer.
