5.4 Residual-current-operated protective deviceDanger due to electric currentFor an installation of r.c.d. protection, it shall be observed that this must be of “universal-current sensitivity”. In accordance with EN 50 178, Section. 5.2. other types of current-operatedprotective devices may not be used. To ensure as high a degree of reliability as possible , werecommend a tripping current of 300 mA.5.5 Inverter output5.5.1 Motor connectionThe motor leads are connected to the terminals: PE, U, V, W. Comply with the motor data (ratingplate) regarding the type of connection (Y or D). U / f setting see motor setup.Information• For each Controller can be attached only one motor, parallel operation of several motorsis not allowed!• The maximum length of the screened motor cable is 10 m, a longer cable is not permis-sible!5.5.2 Disconnection between controller and motor (repair switch)Ideally, a repair switch should be installed before the controller (supply line disconnect).In the case of complete disconnection (entire load) after the controller, the enable (controller OFF /ON) must be disconnected simultaneously. I.e., an additional control contact is needed. Switching onthe motor while simultaneously issuing the enable (ON) achieves secure energizing with low satura-tion of the controller. For this a programming is necessary ( IO Setup Enable ON / OFF).Attention!When switching on the motor plus existing release: under certain circumstances, this can occur underfull modulation of the controller.5.6 Motor protectionMotor protection is possible by connecting thermostats “TB” (thermal contacts) or thermistors “TP”(PTC).A maximum of six individual thermistors (DIN 44081 or DIN 44082) may be connected in series to asingle device.The unit switches off when a connected thermostat or thermistor has tripped the circuit (interruptionbetween both terminals “TB/TP” or “TK/PTC”. The unit then remains switched off. A programmedfault-indicating relay is triggering.Motor faultDisplay during motor faultPossibilities for re-starting after the drive has cooled down terminals “TB/TP” or “TK/PTC” by:• By switching the mains voltage off and then on again.• By simultaneously depressing the three keys: P, ▲, ▼(if a fault is indicated).• By digital input for remote (enable ON/OFF) or by Reset-input ( IO Setup - Digital Inputs).Attention!• Use a separate screend connection cable for temperature monitoring.• An outside voltage may never be connected to the terminals “TB/TP” and/or “TK/PTC”!• If a bypass circuit is installed, or in the “100%” position on devices with a main switch, the motorprotection inside the controller has no function. In this case, additional motor monitoring may berequired.Operating Instructions Icontrol – model series FXDM Electrical installationL-BAL-E036-GB 1422 Index 008 Part.-No. 00154773-GB13/96
