Motor cut-off relay 2+2S not potential-free - Isolator relay venetian blind 5A MTR12-UC

Motor cut-off relay 2+2S not potential-free - Isolator relay venetian blind 5A MTR12-UC – Eltako – 22400601 – 4010312205211: Motor isolating relay 2+2S not potential-free MTR12-UC mounting type REG, number of connectable motors 2, nominal voltage 250V, frequency 50 ... 50Hz, rated current 5A, motor isolating relay. Stand-by loss only 0.5 watts. 1 division unit. The tubular motors of shading elements and roller shutters must under no circumstances be connected directly in parallel, otherwise reverse voltages will occur via the limit switches and ultimately the motors will be destroyed. For one motor and if the control voltage and motor voltage are 230V, an EGS12Z-UC is sufficient. However, if more than one motor is to be controlled with an EGS12Z-UC or if the control voltage is unequal, an MTR12-UC must be connected for every two motors. The MTR12-UC can be operated in parallel, but requires free contact outputs K2/K3 of the controlling EGS12Z-UC. These are connected to terminals K2/K3 of the MTR12-UC. 1/2 = Motor 1, 3/4 = Motor 2. The up or down functions can be locked using a rotary switch and can be switched off completely. This lock only applies to the maximum of 2 connected motors. This means that individual shading elements or roller shutters can be completely or partially excluded from the automatic function of an overall control system.
