A.4. Electrical connection
Installation altitude
For 480/277V grid systems: The maximum altitude is between 0 and 3500 m above sea level.
For 480V (corner earthed) grid systems: The maximum altitude is between 0 and 2000 m above sea level.
Conductors
See the sections on electrical installation and cable requirements.
Conductor temperature ratings
Model J: Use minimum 60 °C copper conductors.
Model K: Use 75 °C copper conductors only. The wire sizes for the mains supply must be sized for a wire size which is suitable for at least
125% of the rated input current of the motor drive units.
Conduit hubs
In case of connection to conduit, suitable conduit hubs need to be installed in the field. Such conduit hubs must be UL Listed according to UL
Category Code Number (CCN) DWTT/DWTT7 and suitable for the relevant enclosure type rating in accordance with UL 514B and CSA C22.2
No. 18.3.
For type 12 enclosures, it is only allowed to use conduit hubs rated Type 12 or Type 13.
After installation, all unused M20/½" NPT openings must remain closed by means of the delivered blind plugs in order to maintain the defined
enclosure rating. MGE motors are delivered with M20 blind plugs as standard. MLE motors are delivered with ½" NPT blind plugs as standard.
The relevant enclosure type rating can be found on the nameplate of the product.
Recommended ring terminals
Ensure that the used ring terminals are UL certified.
The 480 V supply terminals are suitable for field wiring when used with stranded wires and specific listed crimp terminals manufactured by
Tyco Electronics (E13288).

Ethernet cable connection
The connection of Ethernet cables must be done by connecting the Ethernet cable screen to an earth clamp on the terminal box, to be in
compliance with FCC and ISED requirements.
The recommended Ethernet cable types for earth clamp applications are SF/UTP, S/FTP or SF/FTP, where the cable screen consists of both a
braided and a foil screen.
Torques
See the section on torques.
Line reactors
The maximum line reactor size in front of the drive must not exceed the following values:
