Specifications LowImpedance/HighImpedance Grounding The Symmetra MW is easily integrated into either a lowimpedance (solidly) grounded Wye system, or a highimpedance grounded system. In a lowimpedance grounded system (most common), the power source (utility, generator, or UPS) is solidly grounded. In the event of a downstream ground fault, the fault current will have a path back to the source, and the overcurrent device feeding the faulted part of the installation will trip and isolate the fault. In a highimpedance grounded system, the source is grounded with an impedance (grounding resistor). In the event of a downstream fault, the fault current will be limited by the impedance of the grounding resistor. The value of a highimpedance system is its ability to maintain operation with a given system fault to ground, i.e. the overcurrent device will only trip at linetoline faults or double ground faults. For a highimpedance system to provide enhanced power system reliability and availability, a groundfault monitoring/alarm system is required. Lowimpedance grounding For lowimpedance grounding, verify the presence of the copper midpoint bonding jumper. For location of the jumper, see Ground and AC cable connection in Installation Manual. Connect the output circuit grounding electrode conductor to a grounding electrode in accordance with NEC 999, article 506. Note: Grounding electrode conductor to be supplied by the customer Highimpedance grounding For highimpedance grounding, remove the preinstalled copper midpoint bonding jumper. For location of the jumper, see Ground and AC cable connection in Installation Manual. Install groundfault detection circuit in accordance with NEC 999, article 5036. Note: For highimpedance grounding, the installation must include groundfault detection circuitry. From an external grounding resistor, and through a separate conduit, connect a cable to the output circuit grounding bar. Symmetra MW II 600 kw 480 V Installation 99094E00 7

The overload performances and fault clearings are possible when the system meets specified minimum requirements for breaker settings. A proper breaker coordination study is required to ensure the highest availability of the UPS. This breaker coordination study should be performed focusing on maintaining the fault tolerant characteristics of the Symmetra MW. The following tables provide the optimum settings for the input and output breakers. The settings are specified in the tables below, but some of them can also be found in the Electrical Specification section. See separate manual on parallel systems for information on required breaker settings in parallel systems.

This is the current that would flow in the fault circuit is the fuse was replaced by a link with an infinitely small impedance 8 ka is the maximum peak letthrough current (including safety factor) present during clearing of an internal fault in a 00 kw section or a power module. This maximum peak letthrough current is based on and applicable to utility with prospective shortcircuit currents (Ip) up to 00 ka. During or after a controlled fault clearing, none of the breakers are allowed to trip on the instantaneous trip setting below the specified value. This is also applicable to the upstream breakers, and a check of the instantaneous trip setting in this part of the installation is required. The instantaneous trip setting calculated by a professional engineer in a breaker cooardination study must not disable the functionality of clearing and surviving an internal fault unless there is a written agreement between APC by Schneider Electric and the customer. By ensuring the unit s fault clearing ability (survival skills) i.e. using the correct instantaneous trip settings in the switch gear (installation), maximum power availability in normal operation is obtained for the critical load. Note: The instantaneous trip setting can be calculated when utility Ip is known. An incorrect trip setting can result in limiting the system functionality and jeopardize the load support. 4 Symmetra MW II 600 kw 480 V Installation 99094E00
Note: The instantaneous trip setting must not be derated even though the UPS system is derated in system output power. The system size has no influence on the instantaneous trip setting. Note: For derated systems, the APC Application Team can provide the correct breaker settings and breaker frame sizes. Note: For upstream breakers not mentioned in the table, the APC Application Team can provide the correct breaker settings for online, overload, and trip currents. The following diagram shows a dual utility system in which the upstream breakers are named Q. Correct settings of upstream breaker settings are mandatory. The system can also be configured as a single utility system.
