COVER serii HS – Instrukcja ObsługiCOMEX S.A.11. PrecautionsThis user manual contains the necessary information regarding the installation and use of theCOVER series HS power supplies.Before beginning installation and use, you are asked to read this manual carefully.The UPS must be installed and configured by an authorized service center of the manufactureror distributor. In the case of installation by people without the required experience, there is arisk of users being exposed to health or life. Persons not authorized to install may damage thepower supply, which in this case is not subject to warranty conditions.COMPLETE STANDARDSThe appliance complies with CE-Directives 73/23 and 93/68 (low voltage safety) as well as89/336 (EMC) and the following standards:*IEC62040-1-1*IEC/EN62040-2 EMC CLASS C3*IEC62040-3WARNING - Large leakage currentConnecting the protective conductor (PE) is essential and must be done before connectingthe remaining working cables (power supply, receiving, battery).Grounding should be carried out in accordance with prevailing standards and practical on-site knowledge.The leakage current exceeds 3.5 mA and is less than 1000 mA.When selecting RCCB or RCD devices for immediate operation, the transient and fixedleakage currents that may occur during commissioning must be considered.Automatic residual current circuit breakers (RCCBs) that are sensitive to DC unidirectional(Class A) pulses and are insensitive to transient current pulses shall be selected.Also note that the RCCB or RCD device will conduct the leakage current of the receiver.OperationThere is dangerous voltage in the UPS housing. The risk of contact with such voltage isminimized as the live parts are behind the enclosure. Additional internal protection guardsensure that the device is protected in accordance with IP20 protection class.Normal operation of the device, taking into account recommended operating procedures,does not pose any risk to personnel.All maintenance and service procedures require access to the inside of the machine andshould only be carried out by trained personnel.Battery high voltage > 400 VdcAll maintenance and installation work may be performed by a properly trained servicetechnician.After connecting the battery the voltage at their terminals exceeds 400 Vdc and is potentiallyfatal.警告 危 险警告 危 险警告 危 险警告 危 险
