SCXI -1382 BATTERY PACK INSTALLATION GUIDE
This guide describes how to install and use the SCXI-1382 battery pack
with the SCXI-1000DC chassis.
The SCXI-1382 is a battery pack containing a 12 V sealed lead-acid battery
with a capacity of 26 Ah at a 20 hr rate. This battery pack can power the
SCXI-1000DC chassis when other power sources are unavailable. You can
combine the SCXI-1383 with the SCXI-1382 to charge the SCXI-1382 or
to operate in float mode for uninterruptable power to an SCXI-1000DC
chassis. The SCXI-1383 is a constant voltage, current-limited charger.
There are two versions of the SCXI-1382 battery pack kit. One kit requires
an SCXI-1383 and one does not. If the kit contains an SCXI-1383 power
supply/float charger refer to the SCXI-1383 Power Supply/Float Charger
Installation Guide when setting up the system.

Battery Pack Safety Information
Note Refer to the Read Me First: Safety and Radio-Frequency Interference document
before removing equipment covers or connecting or disconnecting any power wires or
signal wires.
Cautions The battery pack contains a sealed lead-acid non-wet, nonspillable battery.
Do not ship the battery pack without proper packaging or if it is damaged. Retain the
original packaging for future shipping.
Do not carry the battery pack onto a passenger plane. You must ship the battery pack as
cargo.
You must recycle or properly dispose of the battery. In the United States, call
1-800-RE-USE-Pb (1-800-738-7372) for more information.
Never expose the battery to fire or short-circuit the battery.
Do not use the battery pack if it appears damaged.
Always use the supplied charger to charge the battery pack. Follow the documentation
instructions. You can obtain NI documents at ni.com or by contacting an NI sales
representative.
Charging the Battery Pack
The SCXI-1382 battery pack requires 12 to 14 VDC and at least 3.7 A of
power for at least 12 to 14 hours to reach a full charge. Charge the battery
pack as soon as possible after use. If the battery is fully charged, it can
power the SCXI-1000DC chassis for more than five hours. However,
NI recommends that you charge the battery after every three hours of use
to extend the life of the battery pack.
Note NI recommends using the SCXI-1383 power supply/float charger to charge the
SCXI-1382 battery pack. Refer to the SCXI-1383 Power Supply/Float Charger
Installation Guide for charging instructions.
Caution The battery pack contains a sealed lead-acid battery that contains toxic material
(lead) and corrosive fluid (sulfuric acid). Charging can produce explosive gases. Do not
charge the battery in gas-tight enclosures. Charge the battery in a well ventilated area away
from sparks, flames, or smoke. Do not short the battery pack terminals, as this can cause
an explosion or fire. Do not store the battery pack in a discharged state. Do not puncture,
disassemble, mutilate, or incinerate the battery pack. Recycle the battery or dispose of the

SCXI-1382 Battery Pack Installation Guide 4 ni.com
battery pack with automotive battery scrap. The battery charger dissipates heat. Use the
charger in an area with ample air circulation.
Connecting the SCXI-1382 to the SCXI-1000DC Chassis
Caution Only qualified personnel should install the SCXI-1382 battery pack.
To connect the SCXI-1382 battery pack to the SCXI-1000DC, refer to
Figure 1 and complete the following steps:
1. Power off the SCXI-1000DC chassis by switching the power switch on
the SCXI-1000DC front panel to the Οposition.
2. Remove the four 8-32 ×7/16 in. screws that hold the mounting bracket
to the SCXI-1382 battery pack.
3. Using the 8-32 ×5/16 in. and 6-32 ×1/4 in. screws, attach the
mounting bracket to the SCXI-1000DC. Apply a torque of
1.2–1.4 N · m (10.5–12.3 lb · in.) to the screws to secure them.
4. Slide the battery pack assembly onto the mounting bracket and reinsert
the four 8-32 ×7/16 in. screws. Apply a torque of 1.2–1.4 N · m
(10.5–12.3 lb · in.) to the screws to secure them.
5. The chassis and the battery pack are ready for electrical connections.
Connect the green DC power connector (P1) at the end of the cord on
the SCXI-1382 battery pack to the corresponding connector (J1) on the
rear panel of the SCXI-1000DC chassis.
Caution The SCXI-1382 battery pack connector, J2, is an input-only connector for the
SCXI-1383 power supply/float charger. Do not connect the SCXI chassis to this connector.
6. Power on the SCXI-1000DC chassis using the power switch on the
front panel of the chassis.
Note If the SCXI-1000DC chassis does not power up, check the fuse (F3) on the
SCXI-1382 battery pack.
Caution Always replace a bad fuse with a fuse of the same size and rating for continued
fire protection.
