5.7.1.2 Conductors
Conductor types
Model J: Use stranded or solid copper conductors only.
Model K: Use stranded copper conductors only.
Conductor temperature ratings
Model J: Use minimum 140 °F copper conductors.
Model K: Use 167 °F 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.
5.7.1.3 Conduit hubs
Conduit hubs must be UL listed according to UL Category Code
Number (CCN) DWTT/DWTT7 and be 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 also allowed to use type 12 and 13
conduit hubs.
The relevant type rating can be found on the nameplate of the
product.
5.7.2 Three-phase connections
The cables in the terminal box must be as short as possible.
However, the separated protective-earth conductor must be so long
that it is the last one to be disconnected in case the cable is
inadvertently pulled out of the cable entry.
To maintain the cURus mark, additional requirements
apply to the equipment. See the appendix concerning
installation in the USA and Canada.
Model J:
To avoid loose connections, ensure that the terminal block
for L1, L2 and L3 is pressed home in its socket when the power
cable has been connected.
Model K: To avoid loose connections, ring terminals must be used.
Ensure that ring terminals are short enough to stay within the
terminal cover.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
