3. Installation
- EnergyBank is designed for mounting on a vertical surface using suspension holes (to drill holes in the wall use
the mounting template included) or for placing on a flat surface.
- Connect the supply adapter to EnergyBank's input connector (DC IN) and a GSM gateway to the output
connector (DC OUT) using the interconnecting cable included.
- For the acceptable range of operational temperatures see the
"Technical Parameters“
section
,
it is impossible to
operate EnergyBank on places exposed to direct solar radiation or heat sources.
- EnergyBank is intended for indoor use. Keep it away from rain, flowing water, condensing moisture, fog, etc.
- EnergyBank may not be exposed to aggressive gas, acid vapours, solvent vapours, etc.
- EnergyBank is not suitable for such high-vibration environments as means of transport, machine rooms, etc.
4. Function
- Upon power up, EnergyBank works completely automatically and requires no operating personnel. Three LEDs
on the outer cover indicate its statuses as follows:
- green LED - power supply and charging - the equipment is fed from the mains;
- yellow LED - back-up - no mains voltage, the equipment is backed-up;
- red LED - low battery, the equipment will soon turn off.
- When the equipment is connected to the mains, voltage is supplied to the output connector and the accumulators
get charged. This status is indicated by a green LED. When the accumulators get discharged completely, they are
recharged quickly for 6 hours up to their half-capacity and then the charging process decelerates until standby
current only flows into the accumulators. The full capacity is reached in approximately 24 hours of mains
operation. The above mentioned data are for information only because of parameter dispersion and accumulator
ageing. The new device must by charged before use for backup.
- In the event of mains power outage, EnergyBank transits smoothly into the back-up mode, which is signaled by
a yellow LED. The backed-up equipment must be connected at the moment of power outage, otherwise
EnergyBank turns off automatically and you have to apply mains voltage to put it in operation again. Hence, you
cannot disconnect the backed-up equipment and reconnect it (or connect another equipment unit) in the back-up
mode - the back-up mode cannot be recovered after disconnection without reconnection to the mains!
- The accumulator discharging is signalled by a red LED. Another voltage drop below the minimum value on the
accumulators results in the equipment turning off to avoid irreversible accumulator damage by over discharge.
- Turn-off status - no LED is on, the electronics shows the minimum consumption. The equipment transits into
this mode whenever the accumulators get discharged below the minimum value or whenever both the power
supply and backed-up equipment are disconnected. To terminate this status apply mains voltage.
5. Maintenance
- If, as result of ageing, the accumulator capacity goes down or internal resistance goes up, the accumulators can
be replaced with new ones of the same design. There are 10 standard NiMh accumulators of the AA size in the
equipment. These accumulators are placed in a holder and can be replaced without any special tools. If you do
not want to contact the servicing centre, you can replace them yourself.
- Be sure to use accumulators of the same design for replacement - NiMh, size AA. The accumulators need not
have the same capacity as the original ones (1800 mAh), but we do not recommend you to use accumulators with
a lower capacity.
-While replacing the accumulators keep the equipment disconnected from the supply adapter and backed-up
equipment. First loosen six screws on the bottom part, then remove the upper cover and disconnect the
accumulator block cable. After that, remove the board with electronics from the equipment and release four
battery holder screws. Move the whole battery block out of the holder and replace the accumulators. Now take
the above mentioned steps in the reverse order to assemble the system (mind the accumulator polarity, remember
to connect the accumulator block cable).
- Dispose of the used accumulators as required by standards (hazardous waste).
6. Troubleshooting
- When the adapter has been connected, a yellow LED is lighted on EnergyBank, the backed-up equipment has
no power.
Cause: Swapped input and output connectors.
