Recommended Upstream Protection
NOTE: For local directives which require 4-pole circuit breakers:
If neutral conductor is expected to carry a high current, due to line-neutral
non-linear load, the circuit breaker must be rated according to expected
neutral current.

Recommended Cable Sizes
 DANGER |
|---|
|
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 70 mm².
Failure to follow these instructions will result in death or serious injury.
|
Cable sizes in this manual are based on 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 size is based on table 54.2 of IEC 60364-5-54.
If the ambient temperature is greater than 30 °C, larger conductors are to be used in accordance with the correction factors of the IEC.
NOTE: The battery cable sizes given here are recommendations –
Always follow the specific instructions in the battery solution documentation
for battery cable sizes and battery PE cable sizes and ensure that
the battery cable sizes match the battery breaker rating.
NOTE: Recommended cable sizes and maximum allowable cable size may vary
for the auxiliary products. Refer to the installation manual provided
with the auxiliary product.
NOTE: Neutral conductor is sized
to handle 1.73 times phase current in case of high harmonic content
from non-linear loads. If non or less harmonic currents are expected,
neutral conductor can be sized accordingly but not less than the phase
conductor.
