Double Cabling
Tightening torque of the screws ⑥: 9 Nm (±10 %)
⇒ Before attaching the adapter plate ⑥ to the terminal box, check the
O-ring ⑤ inserted into the adapter plate to verify its proper state and
correct position.
6. Connect the wires according to the standard or double cabling connec‐
tion diagram.
Observe the following tightening torques:
Screw tightening torques in Nm (±10 %) for power connection
Terminal box to
2AD100 ... 164
2AD180 ... 225
Fig.6-10: Tightening torque for screws in Nm within the terminal boxes
7. Close and attach the terminal box lid.
Moisten the thread of the mounting screws for the cover ① with liquid
screw lock and attach the cover using all of the mounting screws.
Screw tightening torque: 6.5 Nm (±10 %)
⇒ Before attaching the lid to the terminal box, check the glued-in seal ②
on the terminal box lid to verify its proper state and correct position.
Motor connection requires two power cables if an appropriate single cable
cannot be used because of the large bending radius or because of its dimen‐
sions.
The following connection diagram shows a possible connection.
When planning the double cabling, please note the applicable in‐
stallation regulations at the installation site of the machine.
