4.3.4 UPS connection to each in-cabinet battery pack, terminals (X11, X12, X23) & (X47, X48,X49).As this is a device with class I protection against electric shocks, it is essential to install a protectiveearth conductor (earth connection ( )). Connect the conductor to the terminal (X5), before connecting thepower supply to the UPS input.IMPORTANT FOR YOUR SAFETY: Do not turn the battery fuse holder switch (Q3) or (Q8) located in thebattery cabinet to “On” (Close), until the equipment is switched on completely, it may cause irreversibledamage to the equipment or accidents because the fitter is exposed to ELECTRICAL DISCHARGE DANGERSwhen connecting the UPS with the battery cabinet.The UPS with battery pack will be connected, by connecting one side to terminals (X11), (X23) and (X12) ofthe UPS and the other to terminals (X47), (X49) and (X48) of the battery pack, while adhering to the statedpolarity on the labelling of each part and in this manual, and the color of the cables (red for positive, blackfor negative, blue for middle tap (N) and green-yellow for earth bonding), see figure 14.Keep in mind that if more than one battery pack is supplied, the connection will always be in parallel withthe equipment. For instance, the black cable from the UPS negative terminal to the negative of the firstbattery pack and from this one to the negative of the second battery pack, and so on. Please, proceed inthe same way for red cable for positive, blue for half tap (N) and green-yellow for earthing.Electrical discharge danger. If after starting up the UPS, the battery cabinet needs to bedisconnected, the equipment has to be completely shut down (see section 5.2). Turn off the battery fuseholder switch (Q8) located in the battery cabinet and/or fuse holder switch or switch (Q3) located in theUPS. Wait at least 5 min. until the filter capacitors have been discharged.4.3.5 Main protective earthing terminal ( ) & protective earth bonding terminal ( ).As this is a device with class I protection against electric shocks, it is essential to install a protectiveearth conductor (earth connection ( )). Connect the conductor to the terminal (X5), before connecting thepower supply to the UPS input.Make sure that all the loads connected to the UPS are only connected to the protective earth bondingterminal ( ). The fact that the earthing of the load(s) and/or the battery case(s) or cabinet(s) is notrestricted to this single point will create return loops to earth which will affect the quality of the powersupplied. All of the terminals identified as protective earth bonding ( ), are joined together and to the mainprotective earthing terminal ( ) and to the frame of the device.20INFOSEC UPS SYSTEM - 4, rue de la Rigotière - 44700 Orvault - FRANCE - www.infosec-ups.comHot Line – Tel + 33 (0)2 40 76 15 82 - Fax + 33 (0)2 40 94 29 51 - hotline@infosec.fr – 06 11 AA 59 201 02
