SAFETY PRECAUTIONSIn order to ensure that the unit is used safely, all people installing or handling it must follow the general safety measures and warnings described in this quick guide.

The WRU-10k is a unit designed specifically to be installed in an electric panel or enclosure, and is attached to the DIN rail or panel via an accessory. It has an LED (ON) indicating the presence of voltage. Even if this LED is not on, the user must still verify that the unit is disconnected from all power supplies

INSTALLATION AND START-UP

IMPORTANT !

!

GENERAL DESCRIPTION

Installation on the DIN rail. All active conductors that supply the loads, or the section of the installation that requires earth leakage protection with this unit must pass through the hole. In single-phase installations (phase and neutral, L and N), three-phase installations (phases L1, L2, and L3) or three-phase plus neutral (L1, L2, L3 and N). Depending on the insulation level of the wiring, four cables with a cross-section of 35

2 2mm can be passed through, but 25 mm cables are recommended. All connections must remain inside the electric panel. Remember that when the unit is connected, touching the terminals, opening the covers or removing elements may provide access to parts that are hazardous to touch. Do not use the unit until it is fully installed. The unit must be connected to a fuse-protected power circuit in accordance with its power supply range and consumption. In turn, the power circuit must be equipped with a circuit breaker switch or

2equivalent device to disconnect the unit from the power supply network. A cable section of 1-1.5 mm is recommended for wiring. The recommended torque is 0.5-0.6 Nm and insulation should be removed from 7 mm of cable

This quick guide contains information and warnings that must be followed by the user to ensure safe operation of the unit. The unit should not be used under normal operating conditions until it is installed in its final location in the electric panel.

When it is likely that the unit has lost its safety protection (visible signs of damage), it should be disconnected from the power supply. In such a case, contact a qualified service technician or our S.A.T. (Technical Assistance Service).
