15SALICRU4. Installation.Ŗ Check the Safety instructions, from section 1.2.3.Ŗ Check that the data in the nameplate are the required by theinstallation.Ŗ A wrong connection or manoeuvring, can make faults in theUPS and/or loads connected to itself. Read carefully the in-structions of this manual and follow the stated steps in theestablished order.Ŗ The equipments can be installed and used by per-sonnel with no specific training just with the help of this«Manual» only, less those ones that are hardwired, whichhave to be installed by qualified personnel.Ŗ All connections of the equipment including the control(interface, remote panel, ...), will be done with theswitches at rest and no voltage present (UPS power supplyswitch to «Off»).Ŗ Never forget that the UPS is an electrical energy gen-erator, so the user has to take the needed cautionsagainst direct and indirect contacts.Ŗ When there is only one equipment, omit all the instructionsof this document and their implicit connections as regards toparallel systems.Ŗ Parallel system installation needs a switchgear panel with sep-arate input, output and static bypass protections, and a manualbypass too.This switchgear panel allows isolating only one equipmentfrom the system, when facing any malfunctioning and sup-plying the loads with the rest of equipments during the pre-ventive maintenance or during the reparation of itself, inredundant systems.Under request a manual bypass panel can be supplied for asingle equipment or a particular system.Ŗ In parallel systems, the length and cross section of thecables that go from the switchgear panel till each UPSand vice versa, will be the same for all of them without anyexception.Ŗ Battery circuit is not isolated from input voltage. Haz-ardous voltages can be found out between the batteryterminals and earth. Check that there is not input voltage be-fore doing any intervention on them.4.1. To be considered in theinstallation.Ŗ Depending on the power of the equipment, there is a powercord with plug or it is hardwired for input and IEC outlets orhardwired for output, as connection parts for power. The restof connections are done through the connectors, includingthe connection of the equipment with the battery module.Ŗ Terminals for separate bypass line are only available in TWIN RTmodels higher than 3 kVA .Ŗ Cross cable section of the bypass, input and output lines,will be calculated from the currents stated in the nameplateof each equipment, and respecting the Local and/or NationalLow Voltage Electrotechnical Regulations.Ŗ Protections of the switchgear panel, will have the followingfeatures: For input and bypass lines, type B for RCD devices andC characteristic for circuit breakers. For the output (load feeding), C characteristic for circuitbreaker.Regarding the size, they will be as minimum to the currentsstated in the nameplate of each UPS.Ŗ In the nameplate of the equipment there are only printed thenominal currents as it is stated in the safety standard EN-IEC62040-1. To calculate the input current, the power factor andthe efficiency of the equipment have been considered.Overload conditions are considered as nonpermanent andexceptional operating mode.Ŗ If it is added peripherals to the input, output and/or bypasslike transformers or autotransformers to the UPS, the cur-rents stated in the own nameplates of those elements has tobe considered in order to use the suitable cross sections, byrespecting the Local and/or National Low Voltage Regulation.Ŗ When an equipment incorporates a galvanic isolationtransformer, as standard, as an option or either in-stalled by yourself, either at the UPS input, bypass line,output or at all of them, protections against indirect contacthas to be fitted in (residual current device) at the output ofeach transformer, because due to its specification of isolationit will prevent the triggering of the protections fitted in the pri-mary of the transformer in case of electrical shock in the sec-ondary (output of the isolation transformer).Ŗ Remind you that all external isolation transformers alreadyinstalled or supplied from factory, has the neutral of the sec-ondary connected to earth by means of a cable bridge be-tween both terminals. If it were required an isolated outputneutral, remove this cable bridge, keeping the precautionsstated in the respective local and/or national low voltage reg-ulations.Ŗ According to the most current trends, all the UPSs have bat-teries inside the same rack enclosure of the equipment, butin counterpart the resultant weight in the models from 4 to 10kVA is notoriously high (see the stated weights in the table 13and/or in the own packaging of the equipment).Attending the recommendations stated in section 1.2.3.2. re-garding to weight handling and makes easy the installation ofthis power range in a rack cabinet when the handling laboursare done manually, the battery block has to be removed fromthe equipment according to the procedure described in sec-tion 4.2.4..Ŗ Battery protection is by means of fuse and internal, so it is noaccessible by the end-user.Battery modules have internal protections by fuse, and theyare not accessible by the end-user too.4.2. Reception of the equipment.4.2.1. Unpacking, content checking andinspection.Ŗ To unpacking, see section 4.2.3.Ŗ On receiving the device, make sure that it has not sufferedany damage in transport (impact, drop, ...) and its featurescorrespond with the ones in the order, so it is recommendedto unpack the UPS and make a first visual inspection.Ŗ In case of observing damages, make all pertinent claims tothe transport agency or in their lack to our company.Never start up an equipment when external damagescan be observed.Ŗ Also check that the data in the nameplate sticked in the pack-
