2.1.1 Battery Module (Type A / Type B)
Battery Module is the most basic component of the Battery System and it contains the energy storing battery cells.
There is a Module BMS inside each Battery Module. Module BMS checks the status of a Battery Module by
measuring its voltage and temperature. It also communicates with the SMU to send all measured voltage and
temperature data, and to receive commands to control cell balancing.
There are two types of 8S1P Battery Module depending on the position of terminal’s polarity.
Type A’s plus(+) terminal is on the right side. Type B is on the left.
Type A: EM2031AE003A
Type B: EM2031AE004A

2. Product Description
2.1.2 SMU (String Management Unit)
SMU collects all information about the battery system and controls the battery system by switching the main
power line and controls each Battery Module by cell balancing. SMU calculates the state-of-charge (SOC) and stateof-health (SOH) of the battery system. Key components in the SMU are Rack BMS, MCCB, and shunt resistor. Rack
BMS is the main controller that takes all data from the Module BMS, measures the string voltage and current,
determines the state of the battery and controls the MCCB accordingly.

1-Phase Type A (with System BMS): V044-0004AA
1-Phase Type B (without System BMS): V044-0005AA
SMPS Assembly houses the System BMS and SMPS, which provides power to the System BMS and SMU. Two
options are available for the SMPS depending on the AC input range and cabling: 3 phase and 1 phase. The System
BMS assembly provides data to the external systems (i.e. building management system, UPS, etc.) while controlling
and monitoring all connected Rack BMS.
There are two types of SMPS Assembly: Type A is with System BMS and Type B is without System BMS.

2. Product Description
2.1.4 Rack Frame
Black: V808-00068A
The Rack Frame is used to mount the modules, SMU and SMPS assembly and provides ground connections for SMU
and SMPS Assembly.
(Grounding cable/busbar for the rack frame is necessary for the SMU and SMPS Assembly as they are grounded to
the rack frame when installed. An equipment grounding conductor is required to ground the rack frames together
and to the UPS module).

3. Installing the Product
WARNING
The power terminal cap must be left in place on the power terminal of the tray for insulation.
Be sure to use insulated tools (torque wrench, extension, socket, etc.).
All the instruments must be insulated and no metal articles (e.g. watch, ring) should be present
in the installation area.
All power switches must be turned off in advance.
Prepare a CO2 fire extinguisher, a first aid kit, and an AED (automated external defibrillator)
before installation.
CAUTION
If available, use a mechanical lift for lifting heavy (22 kg [50 lb.]) components. If there is no lift,
two or three workers must move items weighing more than 22 kg (50 lb.).
The ambient temperature range must be 23°C ±5°C during installation.
WARNING—SHOCK HAZARD
Verify with a voltmeter that no power is present on the system before beginning work on the battery
system or other part of the UPS system. Use lock out/tag out procedures to secure the UPS and batteries
Do not contact system connectors or terminals. Follow all applicable safety measures.
Follow all local and national codes and regulations.
3. Installing the Product
Because this product has a battery with more than 300V present when fully assembled, installer must follow
the general safety instructions. This system must be installed by qualified, trained workers familiar with the
required instruments. Use appropriate lifting methods when moving the batteries.
3.1 Grounding the Battery System
Grounding methods and wiring must comply with NEC Article 250.
Grounding is required to prevent electric shock hazards and reduce or eliminate damage caused by electrical noise.
Ground connections and ground wire routing vary significantly depending on system configuration and equipment
layout. Samsung provides grounding strip on top of each rack. See Figure 3-127: Grounding Points (2 EA).
