Check that the screw hasbeen tightened,c Cartridgev Check that the cartridge is in its slot behind the frontwicket door. To do so, open the door by pulling on thenotch situated on the left side panel. Sepam S35 hasa shield on the right, which resembles the memorycartridge door. This shield is not another door; do nottry to open it. Check, by hand, that the 2 threadedscrews have been tightened.Above all, do not insert or remove the cartridgewhen Sepam 2000 is energized,v the cartridge has an identification label on the front.The last 3 characters in the first line of the labelindicate the type of Sepam 2000 (the typecorresponds to the protection and metering functionsperformed). The first 5 characters in the label indicatethe Sepam 2000 model. Ensure that the type ofcartridge matches the Sepam model indicated on theside of Sepam.ExampleS35CR on the cartridge label should match S35CRon the Sepam label.SW2v residual current measurement by sum of 3 currentsSW1v residual current measurement by core balance CT Default positionSW1SW2Default parameter settingFactory-set parameter status:c Microswitches:v they are set for power supply by a 5A secondary current transformer,v residual current measurement by core balance CTc Differential protectionv Id/It = 999% (disabled)v Id>> = 5 Ibv coupl. = Dy11c Control logic time delay:v t = 200 ms,c Restricted earth fault protectionv Iso = 999 kA (disabled)MERLIN GERINMERLIN GERINS35 CR D023CRD02FA102DFASEPAM 2035S35CRD02J1FTBN9540013 C08c ConnectorCheck that all the connectors are correctly connectedto the rear of the device and screwed in.2/8 Use - commissioning
