5 Electrical Installation

5.1 Warnings

During electrical installation, observe the relevant local and
national regulations in addition to the information in this
manual.
WARNING
LEAKAGE/GROUNDING CURRENT HAZARD
Leakage/grounding currents are >3.5 mA. Failure to
ground the SAB and the ISD servo drives properly could
result in death or serious injury.
•
Ensure the correct grounding of the devices by
a certified electrical installer in accordance with
applicable national and local electrical
standards and directives and the instructions
contained in this manual.
WARNING
HIGH VOLTAGE
The SAB contains high voltage when connected to the
supply that could result in death or serious injury.
•
Ensure that installation, start-up, and
maintenance are only performed by qualified
personnel.

5.2 Electrical Environmental Conditions

Compliance with the following electrical environmental
conditions is necessary to enable safe and effective
operation of the ISD 510 servo system:
•
Grounded 3-phase mains network, 400–480 V AC
•
3-phase frequency 47–63 Hz
•
3-phase lines and PE line
•
External controller supply input, 24–48 V DC
(PELV)
•
Observe the national statutory provisions.
•
The leakage current is >3.5 mA. Therefore use a
type B residual current device (RCD).
•
The SAB must be mounted in a control cabinet.

5.3 EMC-Compliant Installation

To obtain an EMC-compliant installation, follow the
instructions provided in chapter 5.4 Grounding and
chapter 5.8 Connecting the Components.

NOTICE
POTENTIAL EQUALIZATION
There is a risk of electrical interference when the ground
potential between the ISD 510 servo system and the
machine is different. Install equalizing cables between
the system components. The recommended cable cross-
section is 16 mm
Danfoss A/S © 12/2015 All rights reserved.
Ground the ISD servo drive with the PE wire of
the feed-in cable (see chapter 5.8 Connecting the
Components).
Ensure that the machine frame has a proper
electrical connection to the flange of the servo
drive. Use the front side flange surface. Ensure PE
connection on that part of the machine. Refer to
®
the VLT Integrated Servo Drive ISD
Design Guide for further information.
Use a dedicated ground wire for input power and
control wiring.
Do not ground 1 SAB to another in a daisy-chain
format.
Keep the ground wire connections as short as
possible.
Follow the wiring requirements in this manual.
Ensure a minimum ground wire cross-section of
at least 10 mm 2 or 2 separate ground wires both
complying with the dimensioning rules. See EN/
IEC 61800-5-1 for further information.
Establish electrical contact between the cable
shield and the SAB enclosure by using metal
cable glands, or by using the clamps provided on
the SAB (see chapter 5.8 Connecting the
Components).
Use high-strand wire to reduce electrical
interference.
Do not use pigtails.
Ensure a minimum distance of 200 mm between
signal and power cables.
Only cross cables at 90°.
