Step 1. Confirm that battery power is not in use by means of the VX-3150DS' front-mounted BATTERY POWER
LED, which is unlit in this case.
Step 2. Loosen the VX-3150DS' BATTERY POWER IN negative terminal screw, then pull out the negative
battery cable.
Notes
• Never remove the positive cable first to avoid battery short-circuit that occurs if the positive cable
should contact the unit chassis or equipment rack.
• Insulate the exposed end of the removed cable with insulating tape to avoid shorting to the other cable.
Step 3. Remove the positive battery cable from the positive terminal in the same manner as Step 2.
Note
Insulate the exposed end of removed cable with insulating tape to avoid shorting to the other cable.
[Disconnecting the battery]
[Installing a temperature sensor]
The temperature sensor located on the VX-3150DS' rear panel is designed to compensate for temperature
changes when charging the battery. It should be mounted on the side of one battery in between 2 batteries
using the supplied thermal insulating sheet to avoid ambient temperature change, thereby maintaining the
temperature of the temperature sensor relatively constant.
For details about battery installation, refer to "9. APPENDIX: Recommendations to the Power
Supply Installation" on p. 26.

(Horizontal installation of batteries)
(Vertical installation of batteries)
Step 1. Clean the exterior surface of the battery using a soft damp cloth.
Note: Avoid using chemical cleaners and solvents that may cause the battery cases to clack or leak.
Step 2. Follow the procedure shown above to attach the temperature sensor to the battery.
Note: The thermal insulating sheet is hard to remove after attached.
