Dip switches The dip switches on the front of the trip unit allow manual settings also when the trip unit is off. LEDs The LEDs on the front indicate the status of the re- lease (on/off) and provide information about the protection tripped when the Ekip TT accessory is connected. Front connector The connector on the front of the unit allows the connection of: • Ekip TT for trip testing; LED-test and signaling of the most recent trip. • Ekip T&P for connection to a laptop with the Ekip Connect program (thus measurement reading, as well as trip and protection function tests are made available for the user). Characteristics of electronic Ekip Dip trip units Operating temperature -25°C…+70°C Relative humidity 98% Self-supplied 0.2xIn (single phase)* Auxiliary supply (where applicable) 24V DC ± 20% Operating Frequency 45…66Hz Electromagnetic compatibility IEC 60947-2 Annex F
Thermal memory All the Ekip Dip trip units include a thermal memory function. The trip unit records the trips which have occurred in the last few minutes. Since the trip causes overheating, in order to protect the cables and let them cool down, the trip unit imposes a shorter delay tripping time in case of a fault. Thus, the system is protected against damage due to cu- mulative overheating. This can be disabled, if needed, by using the Ekip T&P. External neutral Ekip Dip trip units are available in both 3 and 4 poles. The 3-pole version with earth fault protec- tion (G) can be equipped with an external sensor for the neutral phase. In this way, the external neu- tral phase is protected and uninterrupted. Communication • Using the dedicated Ekip Com module, XT2 and XT4 can communicate with Modbus RTU when they are equipped with the following trip units: • Ekip LSI • Ekip LSIG.
