charges or unsafe electrical conditions.

Chapter 1 Important Safety Instructions
3
6. Do not use extension cords to connect the UPS to an AC outlet.
7. Do not plug the UPS input cord into its own output receptacles.
z
zUsage Warnings
1. Before usage, you must unpack the UPS and allow it to adjust to room
temperature (20°C~25°C) for at least two hours to avoid moisture
condensing inside the UPS.
2. The external slits and openings in the UPS are provided for ventilation.
To ensure reliable operation of the UPS and to protect the UPS from
overheating, these slits and openings must not be blocked or covered. Do
not insert any object into the slits and openings that may hinder ventilation.
3. Even though all buttons are in the OFF position, the UPS is not isolated from
the mains. To completely isolate the UPS from the mains, please disconnect
the input power cord.
4. This unit supplies power from two sources, the mains and the batteries.
The output receptacles may have voltage present even when the unit is
unplugged. Unplugging the UPS puts it into battery mode and the batteries
supply power to the connected loads.
5. Route all cords well so that nobody can stand on them or trip over them.
6. When connecting the unit to the power supply, follow the instructions stated
in Chapter 4 : Connections.
7. Ensure that no objects (e.g. rings, necklaces, paper clips, etc) get inside the
unit.
8. In an emergency, switch off the unit, disconnect it from the mains and
contact the responsible customer service representative.
9. Do not connect equipment that will overload the UPS and demand DC
current.
10. Do not connect or disconnect data transmission lines during a thunderstorm.
11. The sum of current leakage from the UPS and its connected loads must not
exceed 3.5 mA.
12. The UPS has a REPO (remote emergency power off) port locating on the
rear. Please see 5.2 Other Operating Details for more information.
13. The UPS must be well grounded due to a possible risk of current leakage.
The unit is equipped with a safety-inspected mains line and must be

4
Amplon M Series
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).
14. Ensure that the sockets on the unit or the earthing-contact wall socket is
freely accessible.
z
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 qualied 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.

Chapter 1 Important Safety Instructions

The following precautions should be observed before replacement of
batteries:
1) Remove watches, rings, or other metal objects.
2) Use tools with insulated handles.
3) Wear rubber gloves and boots.
4) Do not lay tools or metal parts on top of batteries.
5) Disconnect charging source prior to connecting or disconnecting battery
terminals.
z
zDisposal
1. To protect our environment, UPS & batteries must be disposed of in accord-
ance with local laws and regulations.
