Installation & Operating Instructions

4. Electrical Installation
4.1 Grounding the Drive
This manual is intended as a guide for proper
installation. ERIKS cannot assume responsibility for
the compliance or the non-compliance to any code,
national, local or otherwise, for the proper
installation of this drive or associated equipment. A hazard
of personal injury and/or equipment damage exists if codes
are ignored during installation.
This Fenner QD:Neo contains high voltage capacitors
that take time to discharge after removal of the main
supply. Before working on the drive, ensure isolation
of the main supply from line inputs. Wait ten (10) minutes for
the capacitors to discharge to safe voltage levels. Failure to
observe this precaution could result in severe bodily
injury or loss of life.
Only qualified electrical personnel familiar with the
construction and operation of this equipment and
the hazards involved should install, adjust, operate, or
service this equipment. Read and understand this manual
and other applicable manuals in their entirety before
proceeding. Failure to observe this precaution could result
in severe bodily injury or loss of life.
4.1.1 Grounding Guidelines
The ground terminal of each drive should be individually
connected DIRECTLY to the site ground bus bar (through the
filter if installed). Fenner QD:Neo ground connections should
not loop from one drive to another, or to, or from any other
equipment. Ground loop impedance must confirm to local
industrial safety regulations. To meet UL regulations, UL
approved ring crimp terminals should be used for all ground
wiring connections.
The drive Safety Ground must be connected to system
ground. Ground impedance must conform to the
requirements of national and local industrial safety
regulations and/or electrical codes. The integrity of all
ground connections should be checked periodically.
4.1.2 Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at
least equal to that of the incoming supply conductor.
4.13 Safety Ground
This is the safety ground for the drive that is required by
code. One of these points must be connected to
adjacent building steel (girder, joist), a floor ground rod, or
bus bar. Grounding points must comply with national and
local industrial safety regulations and/or electrical codes.
4.14 Motor Ground
The motor ground must be connected to one of the
ground terminals on the drive.
4.15 Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist.
The Fenner QD:Neo is designed to produce the minimum
possible leakage current whilst complying with worldwide
standards. The level of current is affected by motor cable
length and type, the effective switching frequency, the earth
connections used and the type of RFI filter installed. If an
ELCB (Earth Leakage Circuit Breaker) is to be used, the
following conditions apply: -
• A Type B Device must be used
• The device must be suitable for protecting equipment
with a DC component in the leakage current
• Individual ELCBs should be used for each drive
4.16 Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for
the motor cable shield. The motor cable shield connected to
this terminal (drive end) should also be connected to the
motor frame (motor end). Use a shield terminating or EMI
clamp to connect the shield to the safety ground terminal.
4.2. Wiring Precautions
Connect the Fenner QD:Neo according to section 4.3,
ensuring that motor terminal box connections are correct.
There are two connections in general: Star and Delta. It
is essential to ensure that the motor is connected in ac-
cordance with the voltage at which it will be operated. For
more information, refer to section 4.6 Motor Terminal Box
Connections.
It is recommended that the power cabling should be 4-core
PVC-insulated screened cable, laid in accordance with local
industrial regulations and codes of practice.
4.3. Incoming Power Connection
• For 1 phase supply, power should be connected to L1/L,
L2/N.
• For 3 phase supplies, power should be connected to L1,
L2, and L3. Phase sequence is not important.
• For compliance with CE and C Tick EMC requirements, a
symmetrical shielded cable is recommended.
• A fixed installation is required according to IEC61800-5-1
with a suitable disconnecting device installed between
the Fenner QD:Neo and the AC Power Source. The
disconnecting device must conform to the local safety
code / regulations (e.g. within Europe, EN60204-1, Safety
of machinery).
• The cables should be dimensions according to any local
codes or regulations. Guideline dimensions are given in
section 10.4.
• Suitable fuses to provide wiring protection of the input
power cable should be installed in the incoming supply
line, according to the data in section 10.4. The fuses
must comply with any local codes or regulations in place.
In general, type gG (IEC 60269) or UL type T fuses are
