Motor isolating relay, 2 + 2 normally open contacts, not potential-free, 5A/250V AC, for one or two 230V motors. Standby loss only 0.5 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Universal control voltage 8..230V UC. Supply voltage 230V. The tubular motors of shading elements and roller shutters must not be connected directly in parallel under any circumstances, as this would cause reverse voltages via the limit switches and ultimately destroy the motors. For one motor and if the control voltage and motor voltage are 230V, one EGS12Z-UC is sufficient. However, if more than one motor is to be controlled with one EGS12Z-UC or if the control voltage is unequal, one MTR12-UC must be connected for every two motors. The MTR12-UC can be operated in parallel, but require free contact outputs K2/K3 of the controlling EGS12Z-UC. These are connected to the 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 max. 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.
