INSTALLATION AND START-UP This manual contains information and warnings about the RGU-10/RGU-10C which must be followed to guarantee the proper operation of all instrument functions and to maintain it in a safe condition. The equipment must not be switched on until it is finally connected to the electrical board.

CONNECTION DIAGRAMS RGU-10/RGU-10C connection with current emission coil. In the event of powering the equipment before the breaking device (AUTOMATIC SWITCH) in an earth leakage trip situation because of a fault, test or toroid error: Note the cause of the trip on the red display.

RGU-10/RGU-10C connection with current emission coil. The following has to be taken into consideration in the event of powering equipment after the breaking device. The breaking device has to be a manually resettable device. After dripping, the equipment is disconnected losing all information on the reasons for the trip. The system is reset only by resetting the breaking device.
Page 11
The equipment operates to its maximum whenever it is supplied from the installation itself before the breaking device or from an independent auxiliary power supply. However if the power supply from the installation is below the breaking device the system continues to be properly protected even though with limitations in terms of its disconnection performance through lack of power supply.

RGU-10/RGU-10C connection with undervoltage coil. Power supply to the equipment is before the breaking device. This breaking device may be an automatic switch or contactor. Using a CONTACTOR the protection is reset by pressing RESET, or by using an AUTOMATIC SWITCH. The breaking device must be rearmed beforehand.

CONNECTING THE EQUIPMENT IN POSITIVE SAFETY This installation mode provides the most conservative protection from the point of view of personal and property safety in electrical installations. With this type of equipment connection and setting, persons all goods are protected against faults where the earth relay leakage loses its protection capacity.
Page 15
When this type of safety is used using the current emission coil, it can only be assured that the system will trip went the earth leakage relay is not operating correctly. The breaking device has the power to trip using the maximum current coil. (AUTOMATIC SWITCH). The equipment is set by programming by pressing the Std/+ key in positive safety mode.
DESCRIPTION The front of the equipment which is formed by the display, buttons and LEDs, is protected with a sealable plastic cover which has the appropriate holes to access the RESET, TEST and SETTING keys. Generic functions of the LEDs and front keypad: - GREEN LED: Equipment on - RED LED: Leakage trip - YELLOW LED: Pre-alarm...

REMOTE TRIP. When a trip is forced (input terminals 1-2, by applying 230 V) the equipment is tripped and disabled and an "EXT" message is shown on the display in red and also the LED is on. It has to remain permanently in this situation until the change in status no longer exists.
EQUIPMENT SETTING Direct settings By pressing for a long time on any of the direct setting buttons, PROG mode is entered (icon on LCD) and the relay's setting may be changed. While in PROG mode if any other direct function is used (I , Std/+ and Auto), the parameter for the displayed relay can also be set.

Reset pre-alarm setting In the pre-alarm menu the REC function is shown as disabled or enabled.
Setting COMMUNICATION SETUP *(Only for models with communication) One or more RGU-10C instruments may be connected to a computer or PLC in order to automate a production process or an energy control system. As well as the usual operation of each instrument, this system may centralize data at one single point;...

Baud rate The display shows the letters "bd" on the upper left of the screen showing the bauds and shows the baud rate in units of a thousand in the central part of the screen. Repeatedly press the td button to change the baud rate, increasing the value of a digits on the central area of the screen.
If it is an RGU-10C, this SETUP menu is preceded by the communications SETUP menu. If there is no communications, RGU-10 is the only SETUP on the equipment.
