1. Regions such as the United States and Canada require 20% derating for power distribution circuits.
Verication of applicable local standards is required for system installation. Some conguration
restrictions to limit power consumption can allow reduced breaker ratings on a regional basis.
Power connector requirements
Ensure that the site where you plan to install the storage system meets the power connector
requirements.
Table 47 on page 96 shows the power cords and the inline connectors and receptacle types that they
support. Find the power cord row that is appropriate for your site. Ensure that your site meets the
specied power connector requirements.
Attention:
• For reliable operation do not use Ground Fault Circuit Interrupter (GFCI), Earth Leakage Circuit
Breaker (ELCB), or Residual Current Circuit Breaker (RCCB) type circuit breakers with the
DS8900F. The DS8900F is certied for safe operation and compliant with IEC, EN, UL, and CSA
60950-1 standards. If local electrical practice requires leakage detection circuit breakers, they
must be rated at minimum to 300 mA or larger to reduce the risk of outage due to spurious
actuation.
• Do not exceed the wire rating of the facility and ensure that separate protected branch circuits
are used for each cord in planning for redundancy.
