Liebert® eXM™ BDC™
Liebert eXM BDC
! AVERTISSEMENT
Le centre de gravité élevé des appareils présente un risque de renversement lors des
déplacements, pouvant entraîner des dommages matériels, des blessures et même la mort.
Les armoires Liebert eXM BDC et de batterie doivent être correctement préparées et
sécurisées avant d’être levées. Un mauvais levage peut faire tomber les armoires, causant des
dommages à l'équipement, des blessures, voire la mort.
Emerson recommande de soulever les unités en suivant l'une des méthodes suivantes :
• En installant quatre anneaux de levage dans les ouvertures fabriquées en usine, avec un
anneau dans chaque coin de l’appareil, pour ensuite fixer les câbles ou sangles aux anneaux
afin d'effectuer le levage à l'aide d'un mécanisme approprié.
• En plaçant des sangles convenables sur l'armoire Liebert ou de batterie. Les sangles
doivent passer sous l'unité à soulever.
1.5.1
Floor Installation
If the Liebert eXM BDC is to be placed on a raised floor, the UPS should be mounted on a pedestal
that will support the equipment point loading. Refer to the Liebert eXM UPS manual, SL-25648 or
SL-25650, to design this pedestal.
1.5.2
Cable Entry
Cables can enter the Liebert eXM BDC from the top or bottom through removable metal plates.
Some plates have factory-punched holes and others are designed to allow the personnel to punch
holes for fitting and securing the conduit. Once the conduit holes are punched, these plates should be
reattached to the UPS. The conduit size and wiring method must be in accordance with all local,
regional and national codes and regulations, including NEC ANSI/NFPA 70.
NOTE
When installing the UPS, the customer must provide a disconnect with overcurrent protection
at the output of the UPS.
1.5.3
Optional Cabinets
The Liebert eXM BDC must be bolted to right side of the Liebert eXM (see Figure 10).
The Liebert eXM BDC must be cabled and bolted to the Liebert eXM before the UPS and bypass
distribution cabinet are moved into their final position. Connect input wiring to the Liebert eXM BDC
ONLY after the units are internally cabled and positioned.
Battery cabinets may be bolted only to the left side of the Liebert eXM; see Figure 10.

Notes on Tables
Notes apply to Tables 18 through 20.
1. Nominal input current (considered continuous) is based on full rated output load maximum
current includes nominal input current and maximum battery recharge current (considered
noncontinuous). Continuous and noncontinuous current are defined in NEC 100. Recommended
overcurrent protection is based on 80% rated devices.
*The recommended overcurrent protection represents 125% of nominal full load current
(continuous) per NEC 215.
2. Maximum input current is controlled by the current limit setting.
3. Recommended AC input external overcurrent protection is based on 80% rated devices and
maximum input current limit setting.
4. Recommended AC output external overcurrent protection is based on 80% rated devices and full
rated output current.
5. Nominal battery voltage is shown at 2 volts per cell.
6. Input power factor of 0.99 is used for the calculations.
