Power requirements Earth leakage circuit breakers are not recommended for
mains. If earth leakage circuit breakers are required by
the customer or according to local regulations, use the
residual current circuit breaker (RCCB) that is not
sensitive to the single-phase DC pulse and transient
current pulse.
Note: If the requirements are not met, contact Huawei technical support for an
optimized plan.
Water Quality Requirements
If the inlet water contains large granules, install a water ltering device at the
inlet port to prevent pipe blockage.
Table 2-7 describes NetCol5000-A water quality requirements.
