This manual has been compiled with great care. Nevertheless errors and omissions cannot be entirely excluded. The Bender Group cannot accept any liability for injury to persons or damage to property resulting from errors or mistakes in this operating manual.
2.2. Skilled persons Only appropriately qualified personnel may work on Bender devices. Persons who are familiar with the assembly, commissioning and operation of the equipment and have undergone appropriate training are considered skilled persons. Such persons must have read this manual and understood all instructions relating to safety.
2.4. General safety instructions Bender devices are designed and built in accordance with the state of the art and accepted rules in respect of technical safety. However, the use of such devices may introduce risks to the life and limb of the user or third parties and/or result in damage to Bender devices or other property.
The UMA710 module is a configured unit and is only certified and tested in this assembly. Do not make any changes to the components, their password-protected settings or the wiring without consulting Bender first. In each case you should make the settings that are required for adaptation to the application case in question and local conditions.
If the ATICS® detects a supply failure or a fault, an alarm appears on the LCD, the "ALARM" LED lights up, the alarm relay trips (if set) and this alarm is forwarded to other Bender devices (such as an alarm indicator and test combination) via the BMS bus.
If any of the measured values does not fall within the limits, an alarm is triggered. A message appears on the LCD, the "ALARM" LED lights up, the alarm relay trips (if set) and this alarm is forwarded to other Bender devices (such as an alarm indicator and test combination) via the BMS bus. Locating current injector When an insulation fault is detected on an IT system, the integrated locating current injector generates a defined locating current signal to locate the insulation fault.
Protection by special installation. For this measure, please note the following: The protection class I transformer must be installed isolated and must not be connected to the PE conductor. In Bender's ES710 range of transformers, the fixing angles are isolated from the transformer core.
5.3.4. Remote alarm indicator Ex works, the following A+B terminals are provided for the connection of BMS bus devices: Remote alarm indicator, control panels and other Bender-BMS-bus devices can be connected to these terminals. 1. A BMS device or an existing BMS bus with several devices is connected to terminals: The last device at the other end of the bus must be terminated with 120ohm.
