•System and motor status surveillance.
The adjustable frequency drive can also be used for motor
protection.
Depending on conguration, the adjustable frequency
drive can be used in standalone applications or form part
of a larger appliance or installation.
The adjustable frequency drive is allowed for use in
residential, industrial and commercial environments in
accordance with local laws and standards.
NOTICE!
In a residential environment, this product can cause
radio interference, in which case supplementary
mitigation measures can be required.
Foreseeable misuse
Do not use the adjustable frequency drive in applications
which are non-compliant with specied operating
conditions and environments. Ensure compliance with the
conditions specied in chapter 8 Specications.

130BD504.10
Figure 3.3 Proper Mounting with Backplate
NOTICE!
Backplate is required when mounted on railings.
NOTICE!
All A, B, and C enclosures allow side-by-side installation.
Exception: if an IP21 kit is used, there has to be a
clearance between the enclosures:
•For enclosures A2, A3, A4, B3, B4 and C3, the
minimum clearance is 2 ins [50 mm].
•For enclosure C4, the minimum clearance is 3

4 Electrical Installation
4.1 Safety Instructions
See chapter 2 Safety for general safety instructions.
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run
together can charge equipment capacitors even with the
equipment turned o and locked out. Failure to run
output motor cables separately or use shielded cables or
metal conduits could result in death or serious injury.
•run output motor cables separately, or
•use shielded cables or metal conduits.
CAUTION
SHOCK HAZARD
The adjustable frequency drive can cause a DC current in
the PE conductor. Failure to follow the recommendation
below means the RCD may not provide the intended
protection.
•When a residual current-operated protective
device (RCD) is used for protection against
electrical shock, only an RCD of Type B is
permitted on the supply side.
NOTICE!
The adjustable frequency drive is supplied with Class 20
motor overload protection.
Overcurrent Protection
•Additional protective equipment such as short-
circuit protection or motor thermal protection
between adjustable frequency drive and motor is
required for applications with multiple motors.
•Input fusing is required to provide short circuit
and overcurrent protection. If not factory-
supplied, fuses must be provided by the installer.
See maximum fuse ratings in chapter 8.8 Fuses
and Circuit Breakers.
Wire Type and Ratings
•All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•Power connection wire recommendation:
minimum 167°F [75°C] rated copper wire.
See chapter 8.1 Electrical Data and chapter 8.5 Cable Speci-
cations for recommended wire sizes and types.
4.2 EMC-compliant Installation
To obtain an EMC-compliant installation, follow the
instructions provided in chapter 4.3 Grounding,
chapter 4.4 Wiring Schematic, chapter 4.6 Motor Connection,
and chapter 4.8 Control Wiring.
4.3 Grounding
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the
adjustable frequency drive properly could result in death
or serious injury.
•Ensure correct grounding of the equipment by a
certied electrical installer.
For electrical safety
•Ground the adjustable frequency drive in
accordance with applicable standards and
directives.
•Use a dedicated ground wire for input power,
motor power and control wiring.
•Do not ground one adjustable frequency drive to
another in a “daisy chain” fashion.
•Keep the ground wire connections as short as
possible.
•Follow the motor manufacturer wiring
requirements.
•Minimum cable cross-section: AWG 7 [10 mm2]
(or two rated ground wires terminated
separately).
Electrical Installation Instruction Manual
MG11AK22 Danfoss A/S © 03/2015 All rights reserved. 11

For EMC-compliant installation
•Establish electrical contact between cable shield
and adjustable frequency drive enclosure by
using metal cable connectors or by using the
clamps provided on the equipment (see
chapter 4.6 Motor Connection).
•Use high-strand wire to reduce electrical
interference.
•Do not use pigtails.
NOTICE!
POTENTIAL EQUALIZATION
Risk of electrical interference, when the ground potential
between the adjustable frequency drive and the system
is dierent. Install equalizing cables between the system
components. Recommended cable cross-section: AWG 6
[16 mm2].

WARNING
INDUCED VOLTAGE!
Induced voltage from output motor cables that run
together can charge equipment capacitors even with the
equipment turned o and locked out. Failure to run
output motor cables separately or use shielded cables or
metal conduits could result in death or serious injury.
•Comply with local and national electrical codes
for cable sizes. For maximum wire sizes, see
chapter 8.1 Electrical Data.
•Follow the motor manufacturer wiring
requirements.
•Motor wiring knockouts or access panels are
provided at the base of IP21 (NEMA1/12) and
higher units.
•Do not wire a starting or pole-changing device
(e.g., Dahlander motor or slip ring induction
motor) between the adjustable frequency drive
and the motor.
Procedure
1. Strip a section of the outer cable insulation.
2. Position the stripped wire under the cable clamp
to establish mechanical xation and electrical
contact between cable shield and ground.
3. Connect ground wire to the nearest grounding
terminal in accordance with grounding
instructions provided in chapter 4.3 Grounding,
see Figure 4.5.
4. Connect the 3-phase motor wiring to terminals
96 (U), 97 (V), and 98 (W), see Figure 4.5.
5. Tighten terminals in accordance with the
information provided in chapter 8.7 Connection
Tightening Torques.
