Guidance in selecting the quantity and types of equipment, the equipment ratings, interconnections, instrumentation and protection is also provided. This recommendation is
For NEMA 3R, and when environmental options are provided, the battery cabinet will maintain a steady internal temperature of 77o F (+/- 3°F) through an external ambient temperature of
Of the three main subsystems, the battery is what makes the system "uninterruptible". Depending upon the system design, the battery can constitute as much as 50% of the cost of the UPS.
Refer to "Securing the Batteries Using the Battery Retention Strap" on page 21 for instructions on securing the batteries using the buckle strap provided with the battery cabinet.
This document offers a curated overview of the relevant codes and standards (C+S) governing the safe deployment of utility-scale battery energy storage systems in the United States.

Guidance in selecting the quantity and types of equipment, the equipment ratings, interconnections, instrumentation and protection is also provided. This recommendation is applicable for power generation, substation, and telecommunication applications. Scope: This recommended practice provides guidance for the design of stationary dc power systems.
9. DC power system instrumentation, controls, and alarms 9.1 General Control devices, instrumentation, and alarms should be provided in order to both enable monitoring and control of the de po"ver system (e.g., voltages, currents, OCPD operation, temperatures), and to annunciate during abnormal conditions.
Factors such as operating te1nperature, duty cycle, battery life, and deep cycling should also be considered. 6.1 Number of battery strings The number of battery strings in an independent de power system should be considered at the design stage.
