SECURITY ADVICE AND WARNINGS space Please read this chapter carefully and examine the equipment carefully for potential damages which might arise during transport and to become familiar with it before continue to install, energize and work with a measuring instrument. This chapter deals with important information and warnings that should be considered for safe installation and handling with a device in order to assure its correct use and continuous operation. Everyone using the product should become familiar with the contents of chapter »Security Advices and Warnings«. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. PLEASE NOTE By qualified personnel only. ISKRA Company assumes no responsibility in connection with installation This booklet contains instructions for installation and use of measuring instrument. Installation and use of a device also includes handling with dangerous currents and voltages therefore should be installed, operated, serviced and maintained and use of the product. If there is any doubt regarding installation and use of the system in which the device is used for measuring or supervision, please contact a person who is responsible for installation of such system. Installation and use of devices also includes work with dangerous currents and voltages, therefore such work shall be carried out by qualified persons. The ISKRA Company assumes no responsibility in connection with installation and use of the product. If there is any doubt regarding installation and use of the system in which the instrument is used for measuring or supervision, please contact a person who is responsible for installation of such system. Warnings, information and notes regarding designation of the product Used symbos: See product documentation. Double insulation in compliance with the EN 61010−1standard. Functional ground potential. Note: This symbol is also used for marking a terminal for protective ground potential if it is used as a part of connection terminal or auxiliary supply terminals. Compliance of the product with directive 2002/96/EC, as first priority, the prevention of waste electrical and electronic equipment (WEEE), and in addition, the reuse, recycling and other forms of recovery of such wastes so as to reduce the disposal of waste. It also seeks to improve the environmental performance of all operators involved in the life cycle of electrical and electronic equipment. Compliance of the product with European CE directives. Before switching the device ON Check the following before switching on the device: Nominal voltage, Supply voltage, Nominal frequency, Voltage ratio and phase sequence, Current transformer ratio and terminals integrity, Protection fuse for voltage inputs (recommended maximal external fuse size is 6 A) External switch or circuit-breaker must be included in the installation for disconnection of the devices’ aux. power supply. --It must be suitably located and properly marked for reliable disconnection of the device when needed. Integrity of earth terminal Proper connection and voltage level of I/O modules Important: A current transformer secondary should be short circuited before connecting the device. WARNING! Auxiliary power supply can be LOW range (19-70VDC, 48-77VAC). Connecting device with LOW power supply to higher voltage will cause device malfunction. Check devices’ specification before turn it on! Device switch-of Warning! Auxiliary supply circuits for (external) relays can include capacitors between supply and ground. In order to prevent electrical shock hazard, the capacitors should be discharged via external terminals after having completely disconnected auxiliary supply (both poles of any DC supply). Health and safety The purpose of this chapter is to provide a user with information on safe installation and handling with the product in order to assure its correct use and continuous operation. We expect that everyone using the product will be familiar with the contents of chapter »Security Advices and Warnings«. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Real time clock As a backup power supply for Real time clock supercap is built in. Support time is up to 2 days (after each power supply down). Disposal It is strongly recommended that electrical and electronic equipment is not deposit as municipal waste. The manufacturer or provider shall take waste electrical and electronic equipment free of charge. The complete procedure after lifetime should comply with the Directive 2002/96/EC about restriction on the use of certain hazardous substances in electrical and electronic equipment. Battery replacement Some instruments are equipped with a built-in battery. When empty, replace with a corresponding type (Varta, type 6032 CR2032 SLF or equivalent). A battery shall be replaced by an authorized service. The battery lifetime is approx. 6 years. Instruction on battery replacement is given in chapter Battery replacement..
