Liebert® Battery Interface Box™
Liebert® Battery Interface Box™
Product Specification/Installation Sheet—Liebert NXL™, Liebert NX™ 225-600 and Liebert eXL™
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation of your Liebert Battery Interface Box. The Liebert Battery
Interface Box can be used with the Liebert NXL, Liebert NX 225-600 and Liebert eXL systems. Read this document thoroughly before working with
the DC system. Retain this manual for use by installing personnel.
! WARNING
Risk of electric shock. Can cause personal injury or death.
The DC terminal voltage connected to this equipment will exceed 400VDC and is potentially lethal. Be constantly aware that the DC
system contains high DC as well as AC voltages. Check for voltage with AC and DC voltmeters before making contact.
Special safety precautions are required for procedures involving handling, installing and maintaining the DC system. Only properly
trained and qualified personnel wearing appropriate personal protective equipment should be involved in installing the Liebert
Battery Interface Box or preparing the system for installation.
Special care must be taken when working with the batteries associated with this equipment. Observe all DC safety precautions
before working on or near the DC system.
The following precautions must be observed when working on this equipment:
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting DC terminals.
• Determine whether the DC source is grounded. If it is grounded, remove source of ground.
Contact with any part of a grounded DC source can result in electrical shock. The likelihood of such shock will be reduced if such
grounds are removed during installation and maintenance.
! AVERTISSEMENT
Risque de décharge électrique pouvant causer des blessures graves, voire mortelles.
La tension c.c. à la borne de cet équipement dépasse 400 V c.c. et est potentiellement mortelle. Soyez toujours conscient du fait que le
système c.c. contient des tensions c.c. et c.a. élevées. Vérifiez les tensions avec des voltmètres c.a. et c.c. avant d’établir tout contact.
Des précautions de sécurité spéciales sont requises pour les procédures associées à la manutention, à l’installation et à l'entretien du
système c.c. Seuls des employés qualifiés et dûment formés portant l’équipement de protection personnel approprié peuvent se
charger d'installer le boîtier d’interface pour batterie Liebert ou de préparer le système pour l’installation.
Des précautions particulières doivent être prises lors de travaux touchant les batteries associées à cet équipement. Observez toutes
les précautions de sécurité appropriées lorsque vous travaillez sur à proximité d’une source c.c.
Lorsque vous travaillez avec cet équipement, prenez les précautions suivantes :
• Retirez montre, bagues et tout autre objet métallique.
• Utilisez des outils dont le manche est isolé.
• Portez des gants et des bottes de caoutchouc.
• Ne posez aucun outil ni pièce métallique sur le dessus d’une batterie.
• Déconnectez la source de chargement avant de brancher ou de débrancher les bornes c.c.
• Vérifiez si la source c.c. est mise à la terre. Le cas échéant, éliminez la cause de la mise à la terre.
Le contact avec toute partie d'une source c.c. mise à la terre peut provoquer une décharge électrique. Pour réduire de tels risques
d’accident, débranchez les prises de terre avant de procéder à l’installation ou à l’entretien.
This unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J of the FCC rules. These limits provide reasonable
protection against harmful interference in a commercial environment. This unit generates, uses and radiates radio frequency energy and, if not
installed and used in accordance with this instruction manual, may cause harmful interference to radio communications. Operation of this unit in a
residential area may cause harmful interference that the user must correct at his own expense.
Placement and Cable Entry
The Liebert Battery Interface Box should be installed near the DC disconnect. The location should allow access to the box and allow the front door to
be opened for service. Access to the Battery Interface Board (BIB), fuse disconnects and terminal blocks are behind the front door. See Figure 1 for
cable entry layout.
Control Connection
Each Liebert Battery Interface Box contains a Battery Interface Board (BIB). All DC systems must have their Battery Interface Board controls
connected in series. The CAN control cables must be two twisted pair, shielded 18AWG (Belden 9156 or equivalent).
NOTE
Care must be taken to route control cables away from high-voltage cables and busbars.Use recommended knockouts for installing all
cables and use provided tie point to secure, see Figure 2.
NOTICE
Risk of improper installation. Can cause equipment damage.
During system commissioning, Emerson Network Power Liebert Services will set the jumpers on the External Interface Board in the
UPS and the BIB. If another DC source is added to the system after commissioning, it is imperative that Liebert Services reset the
jumpers on the EIB and the BIB.

External Battery Room Temperature Sensor—Optional
Connecting an optional sensor to the BIB to monitor the ambient room temperature will enable the Liebert NXL™ and Liebert NX™ 225-600 to
perform temperature compensation charging. The Liebert eXL™ can detect overtemperatures with the optional temperature sensor installed and
open the battery breaker to prevent thermal runaway, but the UPS does not perform temperature compensation charging.
DC Sense Connections—Optional
Connecting the optional DC sense voltage wires will allow the Liebert NXL™, Liebert NX™ 225-600 and Liebert eXL™ to display the DC source on the
UPS HMI. This connection cannot be used with split-battery bus systems, flywheel systems or any DC system that does not have a valid DC voltage
when the DC breaker is open.
If the DC sense wires are connected to the BIB, the DC source cabinet may require field-installed fuse protection; refer to national and local codes to
verify. The DC sense wires must run from the most-positive DC voltage to the most-negative DC voltage.
DC Breaker Undervoltage Release (UVR) Contacts
If the DC breaker is used as a Module Battery Disconnect breaker (UPS will have control of the breaker), then the 48V UVR contacts must be run to
the BIB.
If the DC breaker is used as a Battery Isolation Switch, then the 48V UVR contacts will not be run to the BIB.
NOTE
If the UVR requires more than 100mA of continuous current or inrush of more than 300W, the Liebert NXLBIBX option is required.
Contact your Emerson representative for details.
CAN Communication Connections
Belkin 9156 (or equivalent) cable must be used to run the CAN Communication Connections. If multiple External Battery Interface Boxes are used,
the CAN cables will connect in a daisy chain from the UPS EIB to BIB #1 to BIB #2 to BIB #N. The CAN cables’ combined length must not exceed
1000ft. (305m).
