NORD Drivesystems Berges-VG - Manual (Page 15)

ƒ As early as the planning stage, ensure that the space provided is adequte for the
drive soas to be able to perform installation, care and sirvicing work unhindered.
ƒ The mounting areas on which the VG are to be fitted must be level, torsionally
resistant and free of vibration. ( levelness
≤ 0,1 mm )
ƒ Align the VG on the mounting surface precisly in line with the machine shaft to be
driven.
ƒ Ensure that the units are mounted free of stresses and strain so as to avoid additio-
nal loading.
ƒ Compensate for minor irregularities ( alignment and angular errors ) by using suitable,
flexible couplings.
ƒ Take appropriate measures to absorb reaction torques.
ƒ Lock mounting points for accessories and attachments and mounting points for the
VG themselves appropriatly to prevent the mounting and attachments points
loosening.
Caution ! Prolonged exposure to sunshine may lead to overheating of the drive.
Provide corresponding guards. No welding work may be carried out on
the drive and the drives may not be used as grounding points for wel-
ding work.
The variable speed gears should be used in the designated moun-
ting position, only
ƒ Use suitable mounting tools or extractors to perform installation and dismantling
work on drive and output elements such as belt pulleys, sprocket wheels, running
wheels or gear wheels and couplings etc. on the gear shafts. On no account may
the part to be fitted be forced onto the shaft by hammering.
Stop!
The lubricant filling quantity of the gears is determined by the installation position.
Always comply with the installation position specified on the rating plate in order to
avoid gear damage.
Caution !
The RGAE of Z design are not stable and must thus be supported approprialely for
installation - until securely attached.
4.4 Electrical connection
Danger !
Electrical connection work must be carried out by a qualified electrician.
The variable speed gear must be suitably earthed.
4.4.1 Connection the main motor
ƒ The main motor of the VG must be connected in accordance with the information
in the terminal box of the motor and in the separate Motor Operating Instructions.
Always note the technical data on the motor rating plate ( Item 8.1 ). ( see also Fi -
gure 3 and Figure 4 , Page 12 ).
