4.1. Grounding the Drive
This manual is intended as a guide for proper installation. Invertek Drives Ltd 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 exists if codes are ignored during installation.
This drive contains high voltage capacitors that take time to discharge after removal of main supply. Before working on the
drive, ensure isolation of main supply from line inputs. Wait ten (10) minutes for 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.
NOTE
Use the dedicated ground terminal to ground the drive. Do not use mounting screws/bolts or chassis
screws for grounding
4.1.1. Grounding Guidelines
The ground terminal of each Optidrive should be individually connected DIRECTLY to the site ground busbar (through the filter if
installed). Optidrive 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.
Ground Fault Monitoring
If a system ground fault monitor is to be used, only Type B devices should be used to avoid nuisance tripping.
Drives with an EMC filter have an inherently higher leakage current to Ground (Earth).
The Optidrive product range has input supply voltage surge suppression components fitted to protect the drive from line voltage
transients, typically originating from lightening strikes or switching of high power equipment on the same supply.
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.
Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
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.
When shielded cable is used for control and signal wiring, the shield should be grounded at the source end only, not at the drive end.
4.2. Wiring Precautions
Connect drive according to section 4.3 Connection Diagrams, 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 accordance with the voltage at which it
will be operated. For more information, refer to section 4.5 Motor Terminal Box Connections.
For recommended cabling and wiring sizing, refer to section 10.2 Rating tables.
It is recommended that the power cabling should be 3-core or 4-core PVC-insulated screened cable, laid in accordance with local
industrial regulations and codes of practice.
