Note: one Charger Baery Pack (CBP) is recommended for every two Extended Baery Packs (EBP)
CAUTION: It is very crical to connect the correct voltage CBP with the UPS intended.
CBP1 is for NXRT-1000
CBP2 is for NXRT-1500
CBP3 is for NXRT-2000/3000
CONNECTING THE INCORRECT BATTERY PACK TO THE UPS MAY RESULT IN DAMAGE TO THE UPS
AND/OR BATTERY PACK WILL VOID THE WARRANTY.
All CBP’s have a dierent DC voltage conguraon intended only for the UPS’s listed above.
PLEASE DO NOT MIX CBP’s AND MAKE SURE YOU ONLY CONNECT THE CBP TO LIKE CBP’s OR UPS
INDICATED ABOVE. DC VOLTAGES ARE MARKED ON BOTH THE UPS AND THE CBP – MAKE SURE
THEY MATCH.
Cauon label on CBP cable connectors - PLEASE CHECK VOLTAGES CAREFULLY

LED Descripon
The Charging LED GREEN indicates that the baery charger in the Charger Baery Pack is charging normally with
the AC power cord aached to the Baery pack. AC power cord is only used for every third CBP installed.
The Baery Test LED GREEN indicates that the DC output of the Charger Baery Pack (CBP) is normal.
To perform the Baery Test:
• Switch the breaker on the rear of the CBP to ON posion
• Press the Baery Test Buon on the front panel of the CBP
• The DC output from the CBP is normal when the Baery Test LED is illuminated
Prior to connecng CBP’s, test each CBP to assure proper operaon.
Charger Baery Pack Operaon
The NXRT UPS System can be connected to mulple Charger baery packs to increase the runme when connect-
ed to the UPS supporng the load. Most UPS Systems are limited to one or two external baery packs because the
UPS is responsible for the recharging and does not have the recharge capacity to handle the addional baeries to
a full recharge. The NXRT UPS System overcomes this limitaon by equipping each Charger baery pack (CBP) with
its own charger, providing the user a way to achieve signicantly more baery backup me.
1. The DC Circuit Breaker on the rear of the CBP connects and disconnects the DC bus voltage from the CBP
to the UPS. The DC Circuit Breaker will also trip to the OFF posion in the event of an over-current condi-
on in the CBP.

2. The CBP’s use a cable shipped with each CBP to “daisy chain” together addional CBP’s to the rst CBP be-
ing connected to the UPS in the appropriately labeled connector, or for connecng the rst CBP to the UPS.
CBP’S “daisy chain” to EBP
Note: do not connect the CBP charger power cord into the UPS receptacle.
3. The AC input cord is for connecng AC ulity to operate the Charger contained in every CBP.
4. The input AC Circuit Breaker will trip to the OFF posion in the event that the internal CBP charger draws
excessive current.

Charger Baery Packs
Charger Baery Pack Installaon
CAUTION: Charger Baery Pack (CBP) Installaon should be performed by qualied service personnel.
1. Verify that the DC circuit breaker on the rear panel of the CBP is in the OFF posion.
2. Turn the UPS OFF and disconnect the UPS Input Cord from the AC wall outlet.
3. Remove the CBP connector cover from the UPS rear panel.
4. Connect the external DC baery cable from the CBP to the appropriate connector on the UPS.
5. Secure the DC baery cable to both the rear of the UPS and the rear of the CBP by using M3 x 8 screws
provided (2 each per connector end).
6. Repeat the above procedure for tesng and securing each addional CBP required.
CAUTION: Do not use extension cords when connecng input AC power to UPS or CBP’s
7. Move the DC circuit breaker on the rear of each CBP to the ON posion. At this point the UPS will need to
be started.
8. If the CBP’s are plugged into an AC source and properly installed, the internal baeries will be charged
when acceptable voltage is present. CBP’s must be charged for a minimum of 6 hours for full baery me.
NOTE: If the CBP is going to be out of service or stored for six months or longer, the baeries must be
recharged for at least 36 hours every six months.
Charger Baery Pack Q & A
1. Which CBP’s do I connect to an AC input source?
• It is recommended that every third CBP be connected to incoming AC ulity to properly charge the
baeries in a complete system. Leaving too many chargers connected may cause an over charge situ-
aon which could damage the baeries and void the warranty.
2. Which LED’s are supposed to be lit on the front of each CBP?
• When an CBP is connected to an AC input source and the unit is charging, a GREEN LED on the front
of the CBP will be illuminated.
3. Are any LED’s on the front of the CBP supposed to be lit if it is not connected to an AC input source?
• No. The UPS and/or the CBP’s that are plugged into an AC input source are responsible for charging the
enre system. The CBP is sll working and has the capability of providing DC voltage when needed. No
LED on the front bezel will be illuminated.
4. The CBP is connected to an AC input source, why does the LED on the front of the CBP turn ON and OFF
intermiently, and does this mean this CBP is not working?
• The GREEN LED on the front of each CBP indicates that the charger contained in the CBP is charging.
Under certain condions when the baeries are 100% charged, the charger in the CBP will shut o
and the LED will no longer be illuminated. This is normal operaon for the CBP. The CBP is working
properly.
5. Why don’t the LED’s on each CBP connected to an AC input source turn ON and OFF at the same me?
• The charger on each CBP funcons independently from the others. One CBP charger may be charging
while another one might be at 100% and the charger turned o. This is normal operaon of the CBP.
