2.7 Power connections
For the motor cable consider
Choice between cable for fixed or floating installation.
Cable must be shielded and suitably sized in terms of insulation and wire sections.
Reticulated polypropylene is the preferred insulation material.
Length (max 100 m); note that conductor-conductor capacitance must not exceed 8 nF.
If cable length exceeds 50 m install a triple 1 mH inductance between drive and motor with rated
current identical to HPD rated current.
Minimum conductor size is 1.5mm2 for HPD2 and HPD5 , 2.5mm2 for HPD8 and 4mm2 for
HPD16.
For the mains power cable
Power cables must not be shielded.
Minimum conductor size is 1.5mm2 for HPD2 and HPD5, 2.5mm2 for HPD8 and 4mm2 for
HPD16.
Input fuses must be rated as follows:

Resolver cable
The cable must comprise 4 twisted pairs with individual shields and one common shield.
Capacitance for the length of cable must not exceed 10 nF; wire size must be no less than
0.35mm2.
Maximum length is 100 m.
EMI filter connection
The connection between filter and drive must never exceed 30 cm. If the distance is less than 15
cm unshielded cables are possible, otherwise a shielded cable must be used.
Earth connections
To reduce the length of individual conductors that must be connected to earth we recommend
using an earth busbar located as near as possible to the drive.
The busbar must be made of copper to
