4.3 Mounting of EDrive Motor Controller
Mount the EDrive motor controller in a location that is only
accessible to qualied personal.
The EDrive must be installed within 300 ft of the BEFx Fan.
See Fig 12. For more information about the EDrive E3 please
refer the Installation & Operating Manual.
4.4 Grounding Guidelines
The ground terminal of each EDrive E3 should be individually
connected DIRECTLY to the source breaker panel ground
bus bar (through the lter if installed). EDrive E3 ground
connections should not loop from one drive to another, or
to, or from any other equipment. Ground loop impedance
must conrm 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 ground 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 oor ground rod, or bus bar.
Grounding points must comply with local 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 EDrive E3 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 lter 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 EDrive E3.
4.5 EMC Filter Disconnect
Drives with an EMC lter have an inherently higher leakage
current to Ground (Earth). For applications where tripping
occurs the EMC lter can be disconnected (on IP20 units
only) by completely removing the EMC screw on the side of
the product.
Remove the screw as indicated right.
The EDrive product range has input supply voltage surge
suppression components tted to protect the drive from line
WARNING
For installation in the United States, branch
circuit protection must be provided in
accordance with the National Electrical Code
(NEC).
!
AVERTISSEMENT
For installation in Canada, branch circuit
protection must be provided in accordance with
the Canadian Electrical code
Pour l’installation au Canada, la protection de circuit
de branche doit être fournie conformément au Le code
canadien de l’électriticé.
