3 Installation 3.1 Introduction This chapter contains all the necessary information for the correct unpacking, positioning, cabling and installation of the MINIpower PLUS UPS. ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BY AUTHORISED ELECTRICIANS OR BY QUALIFIED PERSONNEL. UNINTERRUPTIBLE POWER SUPPLIES LTD.
3.3 Batteries The standard batteries for the UPS are sealed, maintenance free, internally mounted and will typically be connected when the UPS is commissioned. The battery life depends very much on the ambient temperature. A temperature range between +18° and +23°C will achieve the optimum battery life. If the UPS is delivered without batteries, Uninterruptible Power Supplies Ltd.
3.5 Positioning The MINIpower PLUS is a compact and light UPS and can easily be moved to its final position. The UPS should be located where: • Humidity and temperature are within prescribed limits. • Fire protection standards are respected. • Cabling can be performed easily. • Access is available for service or periodic maintenance. • Required cooling air flow is possible. • The site air conditioning system has sufficient capacity. • Dust or corrosive/explosive gases are absent.

1. Wire up the Input-Output connector using insulated cable (min. 2.5mm2). 2. Insert the connector into the plastic housing and secure using the screws supplied. Secure the wires to the housing using the cable grip. 3. Remove plug cover by removing its screws. 4. Put the Input-Output connector into the plug [9] on the rear of the UPS, and secure to its case using the screws supplied (Figure 3.3). 5. Check all UPS loads are OFF and connect them to the output socket. 6.
Figure 3.5: Terminals 3.8 Expansion of Autonomy Ensure the UPS has been switched off and disconnected from the mains supply before proceeding with connections The UPS is complete with connections for additional battery cabinets. One or more extra battery cabinets can be fitted to a single cabinet UPS as follows: 1. Loosen screws 1 and 2, but do not unscrew them completely. 2. Slide the protective casing so that the connectors located inside the box are completely accessible. 3.
4 Operation 4.1 Commissioning The MINIpower PLUS UPS is a high quality electronic machine that must be commissioned by a fully trained and authorised Uninterruptible Power Supplies Ltd. field service engineer before being put into use. The commissioning of the UPS involves the connection of the UPS and battery, the checking of the electrical installation and operating environment of the UPS, the controlled start-up and testing of the UPS and customer training.
4.3 Operating Principles When the mains supply is present, the input voltage is filtered and rectified by a special input stage (power factor corrector) which optimises the use of the mains supply, so that the power factor becomes practically unitary, and compensates for any voltage fluctuations. This stage supplies the inverter even in conditions of very low mains voltage.
4.4 Operating Modes There are three main operating modes • Mains operation • Battery operation • Bypass operation 4.4.1 Mains Operation This is the normal operating condition: • The mains supply is converted to DC by the power factor corrector • The inverter reconstructs a sinusoidal voltage from the DC supply • The output filter provides smoothing of the output voltage • The batteries are continually charged 4.4.
4.5 Basic Operation 4.5.1 Switch On Press button Display shows The status indicator shows starting (red, yellow, green) The display shows the operating status 4.5.2 Switch Off With the UPS operating normally (example) Press button for a few seconds The acoustic warning signal sounds repeatedly and the UPS switches off after 5 seconds.
4.6 Displays and Alarms The main messages provided by the alphanumeric display in the three different operating modes are shown below. UPS On Mains Indicates normal operating status, when mains voltage is present. On Battery Indicates that there is no mains power and the UPS is using its batteries to supply power. On By-pass Indicates that by-pass operation has been turned on: the output of the UPS is connected directly to the mains.
4.6.1 Warning Signals Indication and Sound Message Description Solid Green No Sound UPS on Mains IN xxxV Normal operation. Mains OK and load within limits. Fast flashing Green UPS on Mains No sync mains xx.xHz Frequency of the output voltage not synchronised with the input voltage.
4.7 Customising the Operating Mode 4.7.1 Button Functions The buttons on the front panel of the UPS are used to access various menus Button Function • Exit a function without modifying it • Go up a menu level • Exit the main menu and return to status display • Silence the buzzer • Select previous function • Increase a value • Select a new item within the function (e.g. go from DISABLED to ENABLED) • Select next function • Reduce a value • Select a new item within the function (e.g.

Bypass Bypass Enable Forced Mode DIP Speed Off-Line Mode If enabled, the UPS manages bypass operation automatically. If disabled, the UPS will never switch to bypass and will switch off in the event of sustained overload or fault. If enabled, the UPS is set to premanent bypass condition. When Forced Mode is disabled, this alters the speed of bypass intervention. SLOW: for loads which aremay cause high peak demands and are insensitive to input voltage disturbance. STANDARD: normal condition.
Batteries Capacity Manag. and ADVANCED MODE: The end of autonomy warning is based on the power being drawn by the load and is displayed as remaining autonomy time. SIMPLE MODE: The end of autonomy warning is calculated from the battery terminal voltage.

5 Maintenance 5.1 Introduction ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BY AUTHORISED ELECTRICIANS OR BY QUALIFIED INTERNAL PERSONNEL. TO ENSURE OPTIMUM OPERATION OF THE MINIpower PLUS SERIES UPS AND CONTINUOUS AND EFFICIENT PROTECTION OF THE CONNECTED LOAD IT IS RECOMMENDED THAT THE OPERATIONAL PARAMETERS AND CALIBRATIONS OF THE UPS AND THE BATTERIES ARE CHECKED EVERY 6 MONTHS. 5.
• Static switch operation. • Battery status. • Load characteristics. • Integrity of alarm and monitoring systems. • Operation of all installed options. Preventative maintenance inspections form an integral part of all Extended Warranty Agreements (maintenance contracts) offered by Uninterruptible Power Supplies Ltd. For further details on Extended Warranty Agreements please refer to section 2.3.
6 Troubleshooting 6.1 Potential Problems and Solutions Problem Possible Solution When the UPS is switched on, the buzzer sounds and the red warning light makes alternating short-long flashes, then the UPS switches off after 15 seconds The connection of the neutral conductor is incorrect: swap the connections of the neutral and phase input leads, or exclude the neutral sensor. The UPS works but a short beep is heard every 12 seconds and the yellow warning light is lit without flashing.
