To avoid the “FAULT” relay tripping, it isfitted with a time delay.Warning: when the device is supplied directlyfrom the transformer’s secondary side, it isnecessary to protect it from possible overvoltagesthat could damage the electroniccircuit. We recommend to use our surge-limiterPT 73-120 or PT 73-220 (220 V CA).installationThe T thermometer should never be installedon the transformer or inside its metalenclosure due to its operating temperaturelimits (see table opposite). it can be installed in the low voltage switchboard(or on a wall) either horizontally or vertically(see table opposite for fixing details). it is recommended, especially for an installationin an LV switchboard, to retain a minimumclearance to other equipment (take intoaccount the highest voltage) or heat sourcesand ensure adequate ventilation. Take carealso to the highest voltage according to theinsulation distances. connections:PT 100 sensors are to be connected to the Tdigital thermometer between the connectingterminal attached to the transformer and the Tdigital thermometer’s plug-in connector.It is not supplied by France Transfo.See diagram opposite.Warning: since the transformer is of thermalclass F, the T digital thermometer must beprogrammed with a maximum temperature of150 °C for alarm 1 (L1) and 160 °C for alarm 2(L2). France Transfo is in no way liable for anydamage to the transformer should thesemaximum temperatures not be complied with.The following conditions must be compliedwith- use screened and braided cables(20 twists/meter)- minimum conductor cross-section: 1 mm 2- wiring should not pass near power circuits- maximum length of connection: 300 m- minimum clearances to live parts: see above.- wiring should not be attached to any live partof the transformer- the LV panel should be earthed.insulationminimum clearance(kV)(mm)7,2 27012 45017,5 45024 45036 650advised by France Transfoconnection diagramfor the T digital thermometerFrance TransfoBP 10140F 57281 Maizières-lès-Metz Cedextel.
