GE UR8LH Integrated relay protector

High electrical voltages due to incorrect connections! Danger to life or risk of bodily injury! ⇒ Only equipment and lines carrying protective extra low voltage (PELV) may be connected to connectors and terminals with voltages ranging from 0 to 50 volts. ⇒ Connect only voltages and circuits safely isolated from dangerous voltages. Isolation can be achieved, for example, by using safe isolation transformers, optocouplers or power supply independent battery operation.

Protection against dangerous movements

 Dangerous movements can be caused if the connected motors are not controlled correctly. 

There are various causes of dangerous movements: 

• faulty wiring or cable connections 

• operating the components improperly 

• defective measured value transmitters and primary detectors

• defective components • errors in the software

These errors can occur just after the equipment has been switched on or after an indefinite period of time. The monitors in the drive components virtually exclude failure in the connected drives. However, personnel safety requires that additional measures be taken to ensure correct operation. Faulty drive motions which are influenced by the type of control and the operating status cannot be entirely excluded until the installed monitors take effect.

Dangerous movements!

 Danger may result in equipment damage, personal injury or death! ⇒ Personal safety must be ensured by higher-level, monitoring at the installation or precautionary measures for the reasons listed above. These are provided by the plant manufacturer according to the specific conditions of the plant based on a danger and malfunction analysis. The safety regulations in effect for the plant are included herein.
