UPS Installation Plan and Unpacking3-16 Eaton ® Power Xpert® 9395C UPS Installation and Operation Manual P-164000821—Rev 01 www.eaton.com/powerqualityl The UPS battery aux signal wiring from the UPS must be connected to the battery disconnect device.l The REPO feature opens all contactors in the UPS cabinet and isolates power from your critical load. Localelectrical codes may also require tripping upstream protective devices to the UPS.l The REPO switch must be a latching-type switch not tied to any other circuits.l A jumper wire must be connected between pins 1 and 2 on TB1, if the normally-closed REPO contact is notused.l REPO wiring should be a minimum of 22 AWG and a maximum of 14 AWG.l The REPO switch wiring must be in accordance with NEC Article 725 Class 2 requirements.l The maximum distance between the REPO and the UPS cannot exceed 150 meters (500 feet).l Alarm relay contacts have a maximum current rating of 5A and a switched voltage rating of 30 Vac and 28Vdc.l Alarm relay wiring should be a minimum of 22 AWG.3.3 Inspecting and Unpacking the UPS CabinetsThe UPS cabinet is divided into two sections palleted separately for shipping. The sections are shipped boltedto wooden pallets (see Figure 3-10 and Figure 3-11) and protected with outer protective packaging material.WARNINGThe UPS sections are heavy (see Table 3-1). If unpacking and unloading instructions are not closelyfollowed, the cabinets may tip and cause serious injury.AVERTISSEMENT!Les sections de l’onduleur sont lourdes (voir le Table 3-1). Suivre attentivement les instructions dedéchargement et de déballage pour eviter de renverser les armoires, ce qui pourrait causer degraves blessures.CAUTIONTo prevent damage to the wiring channel and wiring in the ISBM section base when lifting ormoving the cabinet:l Lift and move the ISBM section using only the front or rear forklift slots.l Verify that the forklift forks are in a horizontal position before inserting them into the forkliftslots. DO NOT angle fork tips upward.l Insert the forks all the way through the base. DO NOT insert forks partially into the base to movethe cabinet.NOTE On all 9395C-1100 models that will be fed by a site generator at any time it isrecommended to have an “On Generator” sensing input connected and provenfunctional. This allows the UPS to optimize its operation with the generator. Thisfunction includes reduced input current and battery current limits, slower walk-in toease the load step on the generator initially, and HIGH ALERT mode for ESS.HIGH ALERT mode is desired because any loads with a leading power factor willnot be seen by the generator. Rectifier operation will be much softer while ongenerator thereby increasing overall system stability.
