General Manual
PowerWalker Uninterruptible Power Supply
This manual contains important safety precautions, general UPS instructions and useful hints that should be followed during installation, operation and maintenance of the UPS and batteries. Before using the product, please also read the second manual that covers series-specific information.
I. Safety & Emergency
1. This is a product for commercial and industrial application (Class A). Installation restrictions or
additional measures may be needed to prevent potential disturbances.
2. Do not allow liquids or any foreign object to enter the UPS. No containers with liquids shall be placed
on the UPS or in close vicinity.
3. The utility power outlet shall be near the equipment and easily accessible. In the event of an
emergency, press OFF button and disconnect the power cord from the AC power supply.
4. In the event of fire in the vicinity, please use dry powder fire extinguishers.
5. Even after the unit is disconnected from the input socket, internal components are still connected to
the battery which is potentially dangerous. If any internal inspection or replacement of the battery is required, please contact a qualified technician.
6. Please recycle all possible components. The batteries are not to be disposed in your domestic waste
container.
7. Installation and usage must be performed in accordance with the local electric regulations and safety
requirements. Please check if protected equipment or environment has any special requirements.
II. Information
1. Uninterruptible Power Supplies are designed to protect sensitive electronic equipment from power
outages and interference. It is equipped with many features that allow any attached equipment to operate longer and with higher reliability.
2. The product is pluggable to the wall socket and if your version is delivered with batteries already
installed, it can be operated by laymen.
3. Icon Φ on the rating label stands for phase symbol.
4. This product complies with the safety and environmental regulations in EU.
III. Preparation
1. This unit is intended for installation in a controlled environment. Operating under following
conditions is prohibited:
Combustible gas, corrosive substance or heavy dust. Extraordinarily high or low temperature. Standing or running water or extreme humidity. Exposed to direct sunshine or near any heating apparatus. Serious vibrations.

Outdoor. *for temperature and humidity limits please check product specification
2. Inspect the packaging carton and its contents for damage. Please inform the transport agency
immediately should you find signs of damage.
3. Inspect the unit, make sure that nothing is damaged.
4. Please keep the packaging in a safe place for future use (e.g. storage, transportation).
5. Condensation may occur if the UPS system is moved directly from a cold to warm environment. The
UPS system must be absolutely dry before being installed. Please allow at least two hours for the UPS system to acclimate the environment.
6. The utility power outlet shall be near the equipment and easily accessible.
IV. Installation
1. To reduce the risk of overheating the UPS, do not cover the cooling vents.
Input connection
2. Please use only original approved CE-marked input cable to connect the UPS to power.
3. Connect the UPS system only to a grounded (two-pole, three-wire) shockproof outlet which must be
easily accessible and close to the UPS system.
4. Do not plug the UPS into its output.
5. Place cables in such a way that no one can step on or trip over them.
Output connection
6. Please use only approved CE-marked power cables to connect the loads to the UPS system.
7. The connected equipment must not exceed the UPS unit’s rated power capacity. Otherwise, an
overload condition may occur and cause the UPS unit to shut down or trip the circuit breaker.
8. During the installation of the equipment, it should be assured that the sum of the leakage currents
of the UPS and the connected loads does not exceed 3.5mA.
9. Do not connect any load with high in-rush current, because it may damage the unit. For small line
interactive type UPS, even a laser printer or scanner can create a problematic surge, while for online type UPSs it could be caused by a motor.
10. Carefully connect household or other appliances to the UPS output, because many of them can
overload the UPS (e.g. vacuum cleaners, hair dryers, etc).
11. Refrain from connecting a power strip or surge limiter to the UPS’s output, as power strips might
have a higher rating than the UPS.
Communication and signalling
12. For models with a communication port, connect the appropriate cable (e.g. USB or RS232 between
UPS and PC)
13. USB port and RS-232 port cannot work at the same time.
14. For models with RJ11/RJ45 surge protection, you can connect a modem or a phone line to RJ11/RJ45
“IN” port on the back panel of the UPS unit. Connect from “OUT” port to the computer with another cable. This will protect your equipment from surges on a communication cable.
15. Please be aware that surge protection might limit your Internet bandwidth.
16. In selected models, EPO plug (Emergency Power Off) is used to remotely shut down the UPS in case
of emergency (it should not be used for regular switching off the unit). Typically EPO is wired into the building’s safety installation and connected to emergency power off button installed at the entrance. It is used by fire brigades to shut down the electricity in the whole building, including
