2 Introduction The product described in this manual is a transformerless Uninterruptible Power System (UPS). It is a true online, continuous duty, double conversion, solid state, three-phase system, providing conditioned and uninterruptible AC power to protect the customer’s load from all nine power failures. System description The UPSs are used to protect sensitive IT equipment and prevent loss of valuable electronic information, minimise equipment downtime, and minimise the adverse effect

Due to the active front rectifier, the UPS is comparable to a clean resistor load from the mains perspective. Thus, the high input power factor provides minimised cabling and fusing costs due to no reactive power consumption. The low harmonic currents are due to high input power factor and provide the benefits: • No additional losses in wires and cables • No extra heating of transformers and generators with shortened service life • No false circuit breaker tripping and malfunction • No erratic

A parallel UPS system means the linking together of two or more UPS units in parallel so that in the unlikely event one fails the other can automatically take up the load. Traditionally a parallel redundancy configuration is achieved by having a random or fixed master-slave relationship among the UPS units. This master logic gives out individual commands to all the slaves units. Unfortunately this can lead to a single-point-of-failure for the whole system because if the master logic or comm

3. Mechanicalinstallation The UPS and accessories are delivered on a specifically designed pallet that is easy to move with a forklift or a pallet jack. Keep the UPS always in upright position and do not drop the equipment. Do not either stack the pallets because of high-energy batteries involved and the heavy weight Deliveryc heck The UPS is delivered with the following items: • Plastic bag containing: Quick Installation Guide, paper format, multilingual (coming later) User’s Guide,

Figure3 Unloading the equipment from the pallet. Check the information on the type designation label of the equipment to verify that the unit is of the correct type. The type designation label includes ratings, a CE marking, a type code, a part number and a serial number. The serial number is important when making inquiries. It allows individual recognition of the equipment. 1026743 UPS 20-30 kVA, 230 V 0/60 Hz output 11 Revision B User’s Guide

4. Planning beforeinstallation The equipment must be installed in upright position. The equipment requires space to front and back to enable cooling airflow. Service and maintenance require 00 mm clearance on right hand side. All cooling air enters at front and exits at unit rear. The required min. clearance from unit rear to an obstruction is 20 mm. Because the service and user access is in the front there should be reserved enough space (min 600 mm). It is required to arrange ventilat

5. Cabinet installation The required distance for UPS units next to each other is ten millimetres. The same applies to the optional battery cabinets that should be installed next to the UPS cabinet. It is recommended to install the battery cabinet on the left hand side of the UPS. Figure 4 UPS and external battery cabinets. Note! UPS cabinetscan fall over if the shipping brackets arenot used.
