Electrical Connection; Terminal Diagram - Reflex Servitec S Manual De Instrucciones

This operating mode is used for systems with pressure maintenance stations and enables flexible operation at constant pressure.
Water is added depending on the measured filling level in the expansion vessel of the pressure maintenance station. The "LIS"
pressure transducer determines the filling level and sends this value to the controller of the pressure maintenance station. The
controller sends a 230 V signal to the device controller when the filling level in the expansion vessel has fallen below the set value.
The device controller regulates the motor actuator of the motorized ball valve in the "WC" make-up line. This ensures controlled
make-up with water and monitoring of the make-up time and cycles.

DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
• Ensure that the system is voltage-free before installing the device.
• Ensure that the system is secured and cannot be reactivated by other persons.
• Ensure that installation work for the electric connection of the device is carried out by an electrician, and in compliance with
electrical engineering regulations.
The following descriptions apply to standard systems and are limited to the necessary user-provided connections.
1. Disconnect the system from the power source and secure it against unintentional reactivation.
2. Remove the cover.
DANGER Risk of serious injury or death due to electric shock. Some parts of the device's circuit board may still be live
with 230 V even after the device has been physically isolated from the power supply by pulling out of the mains plug. Before
you remove the covers, completely isolate the device controller from the power supply. Verify that the main circuit board is
voltage-free.
3. Install a screwed cable gland suitable for the respective cable. M16 or M20, for example.
4. Thread all cables to be connected through the cable gland.
5. Connect all cables as shown in the terminal diagram.
– For installer supplied fusing, comply with the connected loads of the device , see chapter 5 "Technical data" on
page 11 .
6. Install the cover.
7. Connect the mains plug to the 230 V power supply.
8. Activate the system.
The electrical connection is completed.
