RGU-10 B, RGU-10 B RCM There are 2 models of the device: RGU-10 B, protective device (IEC 60947-2 M). RGU-10 B RCM monitoring device (IEC 62020). Main features: - Measuring in true effective value (TRMS) - Type B differential (IEC 60947-2 Annexed M) - Insulation against transients (IEC 61008.1)
The RGU-10 B device must be installed by authorised and qualified staff. Disconnect the device from the mains and disconnect the measuring devices before handling, chang- ing the connections of or replacing the device.
RGU-10 B, RGU-10 B RCM 3�2�- INSTALLATION While the device is connected, the terminals, opening the cover or removing ele- ments can expose parts that are hazardous to the touch. The device must not be used until the installation process is complete.
RGU-10 B, RGU-10 B RCM 3�- The front frame is attached to cover the mounting points. 4�- Three green pressure tabs on the side runners of the base are attached. 5�- The device is mounted in the hole in the panel with the adapter.
RGU-10 B, RGU-10 B RCM 4�2�- DESCRIPTION OF THE DEVICE The front of the equipment which is formed by the display, buttons and LEDs, is protected with a seal- able plastic cover which has the appropriate holes to access the RESET, TEST and PROG/PAG keys.
RGU-10 B, RGU-10 B RCM 4�4�- KEYBOARD FUNCTIONS The device has 7 keys, Figure 8 1�- Keys accessible with sealed cover and tool RESET, Starts the device after a trip. TEST, Carries out a trip to check the proper operation of the relay.
RGU-10 B, RGU-10 B RCM If the device trips through any event, the screen’s background changes to red and the reason for the trip is displayed. Figure 9: Display RGU-10B� Display messages by device trip, Table 6 Table 6: Display messages by device trip�...
