Important Safety Warnings - Njoy Echo Pro Series User Manual

5. Serial Port: Serial port provides communication between the UPS and
the computer. The UPS can control the computer's shutdown during
a power outage through the connection while the computer can
monitor the UPS and alter its various programmable parameters.
6. EPO (Emergency Power Off) Connector: Enable Power-Off in
emergency from a remote location.
7. HID USB port: Allows the UPS to appear in Windows like a battery
icon. When the power is out, you can still see the battery level and
adjust its settings. Also Windows power management options are
available. In case you need more advanced local management we
recommend you to install and use "PowerMonitor" software.
8. SNMP/HTTP Network slot: Slot to install the optional SNMP card
for remote network control and monitoring.
9. AC Input Inlet: Connect the AC Power cord to a properly wired and
grounded outlet.
10.
Input Circuit Breaker: Provide input overload and fault protection.
11. Output Terminal Block: Connect your equipment directly to UPS.

Important Safety Warnings

Please comply with all warnings and operating instructions in this manual
strictly. Save this manual properly and carefully read the following
instructions before installing the unit. Do not operate this unit before
reading through all safety information and operating instructions
carefully:
Transportation
• Please transport the UPS system only in the original package to
protect against shock and impact.
Preparation
• Condensation may occur if the UPS system is moved directly from
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 to the environment.
• Do not install the UPS system near water or in moist environments.
• Do not install the UPS system where it would be exposed to direct
sunlight or near heat sources.
• Do not block ventilation holes in the UPS housing.

Installation
• Do not connect appliances or devices which would overload the UPS
system (e.g. laser printers) to the UPS output sockets.
• Place cables in such a way that no one can step on or trip over them.
• Do not connect domestic appliances such as hair dryers to UPS
output sockets.
• The UPS can be operated by any individuals with no previous
experience.
• Connect the UPS system only to an earthed shockproof outlet which
must be easily accessible and close to the UPS system.
• Please use only VDE-tested, CE-marked mains cable (e.g. the mains
cable of your computer) to connect the UPS system to the building
wiring outlet (shockproof outlet).
• Please use only VDE-tested, CE-marked power cables to connect the
loads to the UPS system.
• When installing the equipment, it should ensure that the sum of
the leakage current of the UPS and the connected devices does not
exceed 3.5mA.
Operation
• Do not disconnect the mains cable on the UPS system or the building
wiring outlet (shockproof socket outlet) during operations since this
would cancel the protective earthing of the UPS system and of all
connected loads.
• The UPS system features its own, internal current source (batteries).
The UPS output sockets or output terminals block may be electrically
live even if the UPS system is not connected to the building wiring
outlet.
• In order to fully disconnect the UPS system, first press the OFF/Enter
button to disconnect the mains.
• Prevent fluids or other foreign objects from entering the inside of the
UPS system.
Maintenance, service and faults
• The UPS system operates with hazardous voltages. Repairs may be
carried out only by qualified maintenance personnel.
