connected to an earthing-contact wall socket. If the wall socket does
not have an earthing connection, please ground the UPS via the ground
terminal locating at the rear of the UPS (please see 2.5 Rear Panel).

zBattery Precautions
1. Do not open or mutilate the battery or batteries. The released electrolyte is
harmful to the skin and eyes and may be toxic.
2. Do not dispose of the battery or batteries in a fire. The batteries may
explode.
3. The risk of dangerous high voltage is possible when the batteries are still
connected to the UPS even though the UPS is disconnected from the
mains. Do not forget to pull out the battery cable to completely cut off the
battery source.
4. Voltage is always present on the battery terminals.
5. Even when discharged, a battery has the capacity to supply a high short
circuit current, which, in addition to causing damage to the battery itself and
to associated cables, may expose the operator to the risk of burns.
6. Do not keep batteries in storage for periods exceeding 6 months at 25ºC
without being recharged (having been charged to 100% at the beginning of
any such period). If these conditions are not met, the battery performance
can no longer be guaranteed. It is recommend that you recharge the internal
batteries at least once every 3 months and each recharging time should
not be less than 6 hours. If a Delta external battery pack is connected, the
recharging time should not be less than 12 hours.
7. Since new batteries often do not provide full capacity after an initial charge,
it may be necessary to carry out a number of discharge/recharge cycles
before optimum performance is achieved.
8. Servicing of batteries and battery packs should be performed or supervised
by qualied service personnel knowledgeable in batteries, battery packs and
the required precautions.
9. Only use the same type of batteries from the same supplier. Never use old,
new and different Ah batteries at the same time.
10. A battery can present a risk of electrical shock and high short-circuit current.
