Steady-state input frequencies 50 ± 3 or 60 ± 3.0 Hz
PLD input frequencies (<10 seconds) 50 ± 3 or 60 ± 3.0 Hz
1. Regions such as the United States and Canada require 20% derating for power
distribution circuits. For these regions, a minimum 50 A circuit breaker is required for a
40 Amp rated system such as the DS8886. Verification of applicable local standards is
required for system installation. Some configuration 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 79 on page 159 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 specified power connector requirements.
