Electrical Installation
Grounding the Drive
DANGER: This manual is intended as a guide for proper installation. Xylem Water Solution
AB 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.
DANGER: This SRC 311 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.
DANGER: 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.
Grounding Guidelines
The ground terminal of each SRC 311 should be individually connected DIRECTLY to the
site ground bus bar (through the filter if installed). SRC 311 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.
Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the
incoming supply conductor.
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.
Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The SRC 311 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 SRC 311
