Replace the Keypad Battery

When the keypad battery is expired, the date and time go back to the default settings. Use this procedure to
replace the battery.
WARNING! Fire Hazard. Handle keypad batteries properly. Do not charge the battery or disassemble the keypad. If the battery
explodes, it can cause a fire.
To replace the battery, use a Hitachi Maxell "CR2016 Lithium Manganese Dioxide Lithium Battery" or an
equivalent battery with these properties:
• Nominal voltage: 3 V
• Operating temperature range: -20 °C to + 85°C (-4 °F to +185 °F)
WARNING! Fire Hazard. Do not disassemble batteries. Do not expose batteries to heat or fire. If the battery explodes, it can
cause a fire.
NOTICE: Damage to Equipment. The keypad battery stays in use after you de-energize the drive. When you will keep the drive
de-energized for long periods of time, remove the battery from the keypad. When the expected life of the battery is complete,
replace the battery immediately. A dead battery in the keypad can leak and cause damage to the keypad and drive.
The performance life estimate of a new battery is:
• Ambient temperature 20 °C (68 °F): 5 years
• Ambient temperature -10 °C to +50 °C (14 °F to 122 °F): 3.5 years
