WARNING
No braking due to incorrectly set floating clearance "s".
Severe or fatal injuries.
•
Make sure the floating clearance "s" is correctly set, so that the pressure plate
can move up as the brake lining wears.
8. Assemble the remaing parts of the motor you have removed before.
9. Replace the brake control in the event of an interturn short circuit or a short circuit
to frame.
INFORMATION
Replace the setting sleeves [58] if the removal procedure is repeated.

141).
ð
Fan guard with encoder mount [212] or fan guard [35], retaining ring [32]/[62]
and fan [36]
2. Remove the terminal box cover and loosen the brake cable from the brake control/
terminals. Attach trailing wire to brake cables, if necessary.
3. Remove the screws and brake (with brake endshield if necessary) from the stator.
ð
EDRN63 motor: Screws [19]
ð
EDRN71 motor: Screws [900]
4. Replace the gasket [901]. Observe the alignment of the gasket, if necessary.
5. If necessary, replace driver [70], key [71], and retaining ring [62], see chapter

6. Insert the brake cable of the new brake into the terminal box.
7. Position the new brake. Make sure the cable outlet and brake lining carrier gearing
are correctly aligned.
8. Fasten the brake using screws [19] or [900]. Distribute the screws around the
brake and tighten them one after the other.
ð
EDRN63 motor: The screws [19] can be reused. Tightening torque 5 Nm, toler-
ance ±10%
ð
EDRN71 motor: Use new screws [900]. Tightening torque 5 Nm, tolerance
±10%
