CHAPTER 3 - Installation of the drive
3.2 Installation of servomotors SERIES 8
3.2.1 Mechanical installation
There are no special specifications for the installation of servomotors SERIES 8. In any case,
the following notes can be useful as further guidelines.
During installation the characteristics of the standard execution of this series must be taken
into account (see also page 1 of the Catalogue): among them we cite the following.
3.2.1.1 Protection degree
IP55: protection against dust and water sprays.
3.2.1.2 Construction form and type of installation
Servomotors of this series can be mounted only on to a flange. As stated in the drawings
from the Catalogue, there are different possibilities for the various sizes. Table 3/1
summarizes them.

Legend
The exact definitions of the IM code are contained in the standard IEC EN 60034-7 (1993),
part 2179 E; the practical meaning is described hereafter.
IMB5:
flange mounted with passing holes on the flange, horizontal.
IMV1:
flange mounted with passing holes on the flange, vertical, shaft down.
IMV3:
flange mounted with passing holes on the flange, vertical, shaft up.
lMB14:
flange mounted with blind tapped holes on the flange, horizontal.
lMV18:
flange mounted with blind tapped holes on the flange, vertical, shaft down.
lMV19:
flange mounted with blind tapped holes on the flange, vertical, shaft up.
3.2.1.3 Pulleys and couplings
Couplings, pulleys and pinions must be assembled using suitable tools,
avoiding the use of hammers, which could seriously damage the motor. Before the
operation the protection against rust applied on the shaft end must be removed with alcohol
and it is advisable to grease the shaft end itself once the assembling has been completed, to
avoid oxidation.
3.2.1.4 Oil sealer
All servomotors of this series are mechanically prepared to accept an oil sealer on the shaft
(so called "front oil sealer' or "corteco"); in the standard version this sealer is not included and
is supplied or inserted on request (see Order code in the Catalogue).
WARNING !: This sealer will be installed (care of the end user or of ABB on
request), only in case the motor shaft and the oil sealer itself are actually in
contact with oil. In case of the presence of lubricant liquids other than commonly
used mineral or synthetic oils and in the presence of overpressures of these
liquids, contact ABB Servomotors.
