14 PG 720 P Product Information Bulletin
C79000-K7076-C721-01
The PG 720 has an integrated NiMH (nickel metal hydride) rechargeable
battery. This makes the device portable, meaning you can use it without the
external power supply.
Note
You should only start to work with the programming device using battery
power if the rechargeable battery is fully charged. Only then can you be
certain that the maximum operating time is available to you and you are
given enough warning when the battery is low. The battery is fully charged
when the “Power” LED switches from “loading” (orange) to “loaded”
(green) when you plug into the line power supply.
As soon as the device is connected to the network via the power supply unit,
a discharged battery is recharged: if the device is switched off, the battery
can be recharged within two hours; if the device is switched on with reduced
charging current, this takes about six hours.
You should not let the battery become too low. Switch the device off with
the on/off switch after use. If the device is not used for some time, for
example, several weeks, you should remove the battery plug. This is the best
way of saving the battery and ensuring it has a longer life, since it has no
connection to the device. The battery can be found behind the battery cover
on the underside of the device. It can be accessed when the device is placed
in a horizontal position.
The charging process may finish too early if the device is subjected to a
significant change in temperature, or when operating in high ambient
temperatures (max. 40°C). You should wait until your device has been
acclimatized before charging the battery.
!Caution
When disposing of used rechargeable batteries, please observe your local
regulations for waste disposal.
A backup battery (3.6 V lithium battery) powers the hardware clock even
when the power supply to the device is switched off.
!Warning
Risk of severe personal injury or property damage, danger of release of
harmful substances.
Danger of explosion if battery is not handled properly; incorrect disposal of
used batteries can cause the release of harmful substances.
Do not throw a new or discharged lithium battery into an open fire, do not
solder on to the body of the battery. Do not recharge the battery and do not
open the battery by force.
The correct lithium battery is available from Siemens (Order No.:
W79084-E1003-B1).
Return used lithium batteries to the manufacturer/recycler or dispose of them
according to local regulations.
