Additional Information for UL Compliance
TECDrive E3 is designed to meet the UL requirements. For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333
In order to ensure full compliance, the following must be fully observed.
Input Power Supply Requirements
Supply Voltage
200
–
240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed. 240 Volt RMS Maximum
380
–
480 Volts for 400 Volt rated units, + / - 10% variation allowed, Maximum 500 Volts RMS
Imbalance
Maximum 3% voltage variation between phase
–
phase voltages allowed
All TECDrive E3 units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping.
For input supplies which have supply imbalance greater than 3% (typically the Indian sub- continent & parts of Asia
Pacific including China) Invertek Drives recommends the installation of input line reactors.
Frequency

All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above
specified maximum short-circuit Amperes symmetrical with the specified maximum supply voltage when protected
by Class J fuses.
Mechanical Installation Requirements
All TECDrive E3 units are intended for indoor installation within controlled environments which meet the condition limits shown in section
9.1
The drive can be operated within an ambient temperature range as stated in section 9.1
For IP20 units, installation is required in a pollution degree 1 environment
For IP66 (Nema 4X) units, installation in a pollution degree 2 environment is permissible
Frame size 4 drives must be mounted in an enclosure in a manner that ensures the drive is protected from 12.7mm (1/2 inch) of deformation
of the enclosure if the enclosure impacted.
Electrical Installation Requirements
Incoming power supply connection must be according to section 4.3
Suitable Power and motor cables should be selected according to the data shown in section 9.2 and the National Electrical Code or other
applicable local codes.
Motor Cable
75°C Copper must be used
Power cable connections and tightening torques are shown in sections 3.3 and 3.5
Integral Solid Sate short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with the national electrical code and any additional local codes. Ratings are shown in section 9.2
Transient surge suppression must be installed on the line side of this equipment and shall be rated 480Volt (phase to ground), 480 Volt
(phase to phase), suitable for over voltage category iii and shall provide protection for a rated impulse withstand voltage peak of 4kV.
UL Listed ring terminals / lugs must be used for all bus bar and grounding connections
General Requirements
TECDrive E3 provides motor overload protection in accordance with the National Electrical Code (US).
•
Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-50 = 1
•
Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown
in section 4.9.2
9.5.
EMC Filter Disconnect
Drives with an EMC filter have an inherently higher leakage current to Ground (Earth). For applications where tripping occurs the EMC filter can
be disconnected (on IP20 units only) by completely removing the EMC screw on the side of the product.
Remove the screw as indicated below
The TECDrive product range has input supply voltage surge suppression components fitted to protect the drive from line voltage transients,
typically originating from lightning strikes or switching of high power equipment on the same supply.
When carrying out a HiPot (Flash) test on an installation in which the drive is built, the voltage surge suppression components may cause the
test to fail. To accommodate this type of system HiPot test, the voltage surge suppression components can be disconnected by removing the
VAR screw. After completing the HiPot test, the screw should be replaced and the HiPot test repeated. The test should then fail, indicating that
the voltage surge suppression components are once again in circuit.
