Control terminals
Keep the control circuits away from the power cables. For control and speed reference circuits, we recommend using shielded twisted
cables with a pitch of between 25 and 50 mm (1 and 2 in.), connecting the shielding as outlined on page 25
.
Access to the control terminals
To access the control terminals, open the cover.
Note: For information regarding HMI button functions, see "HMI description" on page 31
.
Arrangement of the control terminals
It is possible to lock the
cover with a lead seal.
Note: To connect cables, use a
slotted screwdriver 0.6 x 3.5.
