1.1 Normal (UPS) Mode
While the Liebert EXM BDC is in Normal mode (MBB open; BIB/MIB closed), the UPS is supplying the connected
load with continuous, high-quality AC power. In this mode of operation, the load is protected by the UPS.
1.2 Maintenance Mode
When the Liebert EXM BDC is in Maintenance mode (MBB closed; BIB/MIB open), it provides an alternate path
for power to the connected equipment should the UPS need to be taken out of service for limited maintenance
or repair. In this mode of operation, no power is supplied to the UPS and the load is NOT protected by the UPS.

WARNING
Risk of heavy units tipping over while being moved. Can cause property damage, injury and death.
The Liebert EXM BDC and battery cabinets must be properly prepared and secured for lifting. Improper
lifting may cause the cabinets to fall, causing equipment damage, personal injury and death.
Vertiv recommends lifting the units with one of the following methods:
• Installing four eyebolts in the factory-fabricated holes, one at each corner of the unit, attaching
cables or similar strapping to the eyebolts and lifting with a suitable mechanism.
• Placing suitable straps on the Liebert EXM BDC or battery cabinet. The straps must go under the
unit to be lifted.
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.
Vertiv 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 18 through20.
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.
