Product Information

The UPS system is a device that provides uninterrupted power supply to connected devices during power outages or fluctuations. It features an internal current source (batteries) and output sockets or terminals block that may be electrically live even if the system is not connected to the building wiring outlet. The UPS system operates with hazardous voltages and repairs should only be carried out by qualified maintenance personnel.

Important Safety Warning

Transportation

The UPS system should only be transported in its original package to protect against shock and impact.

Preparation

• Condensation may occur if the UPS system is moved directly from a cold to warm environment. The system must be absolutely dry before being installed.
• Avoid installing the UPS system near water or in moist environments, direct sunlight, or near heaters.
• Do not block ventilation holes in the UPS housing.
• Allow at least two hours for the UPS system to acclimate to the environment before installation.

Installation

• Do not connect appliances or devices that would overload the UPS system (e.g. laser printers) to the UPS output sockets.
• Avoid placing cables where people can step on or trip over them.
• Do not connect domestic appliances such as hair dryers to the UPS output sockets.
• The UPS system can be operated by any individual with no previous experience.

Operation
The UPS system contains no user-serviceable parts. If the battery service life (3~5 years at 25°C ambient temperature) has been exceeded, the batteries must be replaced. In this case, please contact your dealer.

Be sure to deliver the spent battery to a recycling facility or ship it to your dealer in the replacement battery packing material.

Storage

Before storing, charge the UPS 5 hours. Store the UPS covered and upright in a cool, dry location. During storage, recharge the battery in accordance with the following table:

SNMP card: internal SNMP(options)
Loosen the 2 torquescrews (on each side of thecard). Carefully insert the SNMP card and lock the screws The slot called SNMP supports the MEGAtec protocol.We advise that Net AgentII-3 port is also a tool to remotely monitorand manage any UPS system NetAgentII-3Ports supports the Modem Dial-in(PPP) function to enable the remote control via the internet when the network is unavailable. In addition to the features of a standard NetAgent Mini,NetAgent II has the option to add Net Feeler Lite to detect temperature,humidity,smoke andsecurity sensors.Thus,making NetAgent II aversatile management tool.NetAgent II also supports multiple languages and is set up for web-based auto languagedetection.

Relaycard(options)
Mini dry contact card is used foproviding the interface for UPS peripheral monitoring. The contact signals canreflect UPS running status.The card is connected to peripheral monitoring devices via terminal board to facilitate the effective monitoring of the real-timestatus of UPS and timely feedback the statusto monitor when abnormal situation occurs(suchas UPS failure, mains interruption,UPS bypassand ect.). It is installed in the intelligent slotof the UPS.
The relay card includes 6 output ports and one input port.Please refer to thefollowing table for detail.

Emergency Power-off (EPO) (options) EPO is used to shut down the UPS from a distance. This feature can be used for shutting down the load and the UPS by thermal relay, for instance in the event of room overtemperature. When EPO is activated, the UPS shuts down the output and all its power converters immediately. The UPS remains on to alarm the fault.
EPO Connections
NOTE Depending on user configuration, the pins must be shorted or opened to keep the UPS running. To restart the UPS, reconnect (re-open) the EPO connector pins and turn on the UPS manually. Maximum resistance in the shorted loop is 10 ohm. Always test the EPO function before applying your critical load to avoid accidental load loss.Leave the EPO connector installed onto the EPO port of the UPS even if the EPO function is not needed.
Load Segments(options) Load segments are sets of receptacles that can be controlled by power management software or through the display, providing an orderly shutdown and startup of your equipment. For example, during a power outage, you can keep critical equipment running while you turn off other equipment. This feature allows you to save battery power. Each UPS has two load segments:
Load Segment 1: The power shedding battery voltage of this segment can be set by LCD. Load Segment 1: The power shedding battery end of discharge(EOD).
