Electrical Installation
IMPORTANT:
Please read the Safety Information on page Cont. 3 & 4 before proceeding.
WARNING!
Ensure that all wiring is electrically isolated and cannot be made “live”
unintentionally by other personnel.
All control/resolver/motor thermistor inputs,
i.e protected by double insulation are SELV.
Do not connect to non-SELV circuits.
(Refer to Chapter 11: “Technical Specifications” - Insulation Concept).
Note:
Refer to Chapter 11: “Technical Specifications” for additional Cabling Requirements and
Terminal Block Wire Sizes.
IMPORTANT:
The use of variable speed drives of all kinds can invalidate the certification for dangerous
areas (apparatus group and/or temperature class) of explosion-protected motors.
Inspection and certification for the complete installation of servo motors and electronic
components must

Cables are considered to be electrically
sensitive
,
clean
or
noisy
. You should already have
planned your cable routes with respect to segregating these cables for EMC compliance.
If not, refer to Chapter 12: “Certification for the Servo Drive”.
