hazard of electric shock, explosion, or arc flash
All wiring must comply with all applicable national and/or electrical codes. The maximum
allowable cable size is 150 mm2.
Failure to follow these instructions will result in death or serious injury.
|
The maximum number of cable connections per busbar: Two on input/output/bypass busbars; Four on DC busbars; Six on N/PE busbars.
Cable sizes in this manual are based on table B.52.3 and table B.52.5 of IEC 60364-5-52 with the following assertions:
-
90 °C conductors
-
An ambient temperature of 30 °C
-
Use of copper conductors
-
Installation method C
PE cable size is based on table 54.2 of IEC 60364-4-54.
If the ambient temperature is greater than 30 °C, larger conductors are to be selected in accordance with the correction factors of the IEC.
