Important Safety InstructionsREAD AND SAVE THESE INSTRUCTIONS DO NOT DISCARDThis manual contains important safety instructions for the Xantrex GT250 GridTied Photovoltaic Inverter that must be followed during installation andmaintenance procedures.WARNING: Shock HazardRead and keep this Operation and Maintenance Manual for future reference.Before operating and maintaining the Xantrex GT250, read all instructions,cautionary markings, and all other appropriate sections of this manual. Failure toadhere to these warnings could result in severe shock or possible death.Exercise extreme caution at all times to prevent accidents.WARNING: Risk of electric shock, explosion, and arc flash The Xantrex GT250 enclosure contains exposed high voltage conductors. The enclosure doors should remain closed with the latches tightened, exceptduring installation, maintenance or testing. These instructions are for use by qualified personnel, as defined in “AboutThis Manual”, who meet all local and governmental code requirements forlicensing and training for the installation of Electrical Power Systems with ACand DC voltage to 600 volts. To reduce the risk of electric shock, do not perform any servicing other thanthat specified in the installation instructions unless you are qualified to do so. Do not open the cabinet doors if extreme moisture is present (rain or heavydew).153395 Revision Dvii

SafetyWARNING: Multiple sources with risk of electric shock,explosion, and arc flashIn order to remove all sources of voltage from the Xantrex GT250, the incomingpower must be de-energized at the source. This may be done at the main utilitycircuit breaker, the PV array disconnect, and by opening the AC disconnect andthe DC disconnect switch on the Xantrex GT250. Follow the “Lock-out and Tagout (De-energize/Isolation Procedure)” on page xi to de-energize the XantrexGT250 and test all circuits to verify that the inverter is fully de-energized, beforeservicing or maintenance. Opening the AC and DC disconnect switches on theinverter does not remove all power from the inverter. Review the systemconfiguration to determine all of the possible sources of energy. In addition, allowfive minutes for the DC bus capacitors to discharge after removing power.WARNING: Shock hazardIf a ground fault has occurred, there may be potential between TB4 and GND.The normally grounded pole may be energized and ungrounded.WARNING: Amputation hazardThe inverters contain fans with hazardous rotating parts. Keep hands away fromthe fans while the inverter is energized.WARNING: Limitations on useThe Xantrex GT250 inverters are not intended for use in connection with lifesupport systems or other medical equipment or devices. The Xantrex GT250 mayonly be used in grid-interconnected PV systems. They are not suitable for anyother application areas.viii153395 Revision D

SafetyRisksWARNING: Explosion HazardThe IGBT module may explode in the event of a major malfunction.Do not operate the inverter with the doors open.WARNING: Crush HazardThe inverters have a very high balance point and can easily topple down. Onlymove while exercising care.WARNING: Burn HazardInverters contain components that become hot during normal operation. Do nottouch.CAUTIONThe inverters have a supply air and exhaust air area, which must remainunobstructed. The device can overheat and be destroyed if the installation signsare not adhered to.CAUTIONInverter electronics can be destroyed when touched and when electrostaticallycharged. Discharge via earth potential before touching and wear appropriateprotective gear.CAUTIONNo connections or disconnections are to be made at the terminal strips orinternal connectors during operation. Turn the unit off before performing anyterminal work; wait five minutes for the capacitors to discharge and recheck toensure internal components are no longer energized.General Safety Precautions1. When installing the Xantrex GT250 use only components recommended orsold by Schneider Electric. Doing otherwise may result in a risk of fire,electric shock, injury to persons, and will void the warranty.2. Do not attempt to operate the Xantrex GT250 if it has been dropped, orreceived more than cosmetic damage during transport or shipping. If theXantrex GT250 is damaged, or suspected to be damaged, see the Warrantysection of this manual.3. To reduce the risk of electrical shock, lock out, and tag out the XantrexGT250 before attempting any maintenance, service, or cleaning.153395 Revision Dix

SafetyPersonal SafetyFollow these instructions to ensure your safety while working with the XantrexGT250.Never work alone when servicing this equipment. A team of two is required untilthe equipment is properly de-energized, locked-out and tagged-out, and verifiedde-energized with a meter.Thoroughly inspect the equipment prior to energizing. Verify that no tools orequipment have inadvertently been left behind.Qualified PersonnelOnly qualified personnel should perform the troubleshooting and maintenance ofthe Xantrex GT250. Follow all national and local electrical codes and workersafety regulations.Qualified personnel have training, knowledge, and experience in: installing electrical equipment and PV power systems (up to 1000 V), applying all applicable installation codes, analyzing and reducing the hazards involved in performing electrical work,and, selecting and using Personal Protective Equipment (PPE).Safety EquipmentAuthorized service personnel must be equipped with standard safety equipmentincluding the following: Safety glasses Ear protection Steel-toed safety boots Safety hard hats Padlocks and tags Appropriate meter to verify that the circuits are de-energized(1000 Vac and DC rated, minimum)Check local safety regulations for other requirements.x153395 Revision D

SafetyLock-out and Tag-out (De-energize/Isolation Procedure)Safety requirements mandate that this equipment not be serviced while energized.Power sources for the Xantrex GT250 must be locked-out and tagged-out prior toservicing. A padlock and tag should be installed on each energy source prior toservicing.WARNING: Risk of electric shock, explosion and arc flashReview the system schematic for the installation to verify that all available energysources are de-energized. DC bus voltage may also be present. Once allsources of input are identified and isolated, allow five minutes for all capacitorswithin the main enclosure to completely discharge before proceeding.The Xantrex GT250 can be energized from both the AC source and the DCsource. To ensure that the inverter is de-energized prior to servicing, lock outand tag out the Xantrex GT250 using the following procedure.1. Turn the Xantrex GT250 main ON/OFF switch (S3) to the OFF position. This stopsthe inverter from exporting power to the AC utility grid.2. Open, lock out, and tag out the incoming power at the utility main circuit breaker.3. Open, lock out, and tag out the AC disconnect (CB1) on the left door of theXantrex GT250. See Figure 1-10 on page 14 for the location of the ACdisconnect.4. Open, lock out, and tag out the incoming power at the PV array disconnect (ifinstalled.) If a PV array disconnect is not installed, see the WARNING below.5. Open, lock out, and tag out the DC disconnect switch (S1) on the right door ofthe Xantrex GT250 enclosure. See Figure 1-10 on page 14 for the location of theDC disconnect switch.WARNING: Risk of electric shock, explosion and arc flashSchneider Electric recommends the installation of PV array disconnect(s) to ensurepersonal safety during Xantrex GT250 maintenance. Without PV array disconnect(s),once the DC disconnect switch (S1) is open, there will still be DC voltage on the DCterminals TB3, TB4 AND TB5 (PV GND). This voltage may be as high as theopen-circuit voltage of the PV array and is limited to 600Vdc per NEC 690. Useextreme care to avoid these terminals if no PV array disconnect is installed.6. Using a confirmed, accurate meter, verify all power to the inverter isde-energized, as described in Steps 7 and 8. A confirmed, accurate metermust be verified on a known voltage before use.153395 Revision Dxi
