7.3.8.Mounting of IEC/NEMA standard motors with IEC/NEMA adapters
Assembly procedure for IEC standard motors (B5) and IEC plug-in adapters I63 to I100:
Assembly procedure for NEMA standard motors (C-face) and NEMA plug-in adapters N56 to N182:
■ Clean the motor shaft and the ange surfaces of the motor and the adapter and check for damages.
■ Before installing, apply lubrication paste, e. g. Klüberpaste 46 MR 401, to the motor shaft.
■ Wet the retaining screws with thread-locking adhesive (medium strength).
■ Then place the motor on the adapter and tighten the bolts (not included) to the specied torque.
■ Use bolts with minimum property class 8.8. Tightening torque see Table 5 on page E-38.
Assembly procedure for IEC standard motors (B5) and IEC adapters I112 and I132 with geared coupling:
The correct assembly position must be observed when tting the supplied half coupling onto the motor shaft. The half
coupling has to be pushed onto the the motor shaft up to the shoulder and xed there.
■ Clean the motor shaft and the ange surfaces of the motor and the adapter.
■ Heat the half coupling to approx. 80 °C (176 °F).
■ Fit the half coupling onto the motor shaft (shaft shoulder ush with the end of the borehole).
■ Secure the key and the tted half coupling with a set pin by using thread-locking adhesive (medium strength).
■ Check that the half coupling is seated correctly.
■ The contact surface between motor and adapter has to be sealed with appropriate sealant (e.g. Loctite 510 or silicone).
This assembling step is only valid for ATEX applications.
■ Fit the motor onto the adapter. The gearing of the half coupling must t into the gearing of the coupling bush.
■ Fasten the motor onto the adapter using appropriate fastening screws (not included). Tightening torque see page E-38.
Minimum property class 8.8.
