Thermistor
[Installing a thermistor]
The thermistor located on the VX-2000DS' 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
thermal insulating sheet to avoid ambient temperature change, thereby maintaining the temperature of the
thermistor relatively constant.
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 crack or leak.
Step 2. Follow the procedure shown above to attach the thermistor to the adhesive side of thermal insulating
sheet, then attach the sheet to the side of the battery.
Note
The thermal insulating sheet is extremely difficult to remove after attached.
Step 1. Confirm that battery power is not in use by means of the VX-2000DS' front-mounted BATTERY
POWER LED, which is unlit in this case.
Step 2. Loosen the VX-2000DS' 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.
