2004/108/EC) and concerning electrical equipment for use within specified voltage limits (Low-voltage directive 2006/95/EC). This conformity is the result of tests conducted by Hitachi Energy in accordance with the product standard EN 60255-26 for the EMC directive, and with the product standards EN 60255-1 and EN 60255-27 for the low voltage directive.
The IED can be equipped with a test switch of type RTXP8, RTXP18 or RTXP24 or FT. The test switch and its associated test plug handles are a part of the COMBITEST or FT system of Hitachi Power grids, which provides secure and convenient testing of the IED.
The periodicity of all tests depends on several factors, for example the importance of the installation, environmental conditions, simple or complex equipment, static or electromechanical IEDs, and so on. The normal maintenance practices of the user should be followed. However, Hitachi Power grids' recommendation is as follows: Every second to third year •...
Hitachi Power grids protection IEDs are preferably tested by aid of components from the COMBITEST testing system or FT test systems described in information B03-9510 E. Main components are RTXP 8/18/24 test switch usually located to the left in each protection IED and RTXH 8/18/24 test handle, which is inserted in test switch at secondary testing.

M11764-10 v2 An alternative is to open the IED and send only the faulty circuit board to Hitachi Power grids for repair. When a printed circuit board is sent to Hitachi Power grids, it must always be placed in a metallic, ESD- proof, protection bag.
13.4 Repair support M11768-3 v4 If an IED needs to be repaired, the whole IED must be removed and sent to an Hitachi Power grids Logistic Center. Please contact the local Hitachi Power grids representative to get more details. 13.5...
