    Surge Protector 2

    WARNING – All electrical connections must be


    performed by qualified experts only! Unqualified
    handling might lead to shock, burns or death.

    WARNING – Beware of high voltage. Never work


    on a system connected to power or within two min-
    utes after disconnection to avoid electric shock
    hazard.

    CAUTION – The Surge Protector 2 has been de-


    signed for quick installation and replacement. To
    avoid the need for splicing it is designed to be
    installed inside the LORENTZ controller. The Surge
    Protector 2 does not have a waterproof rating. Item no.: 19-005210

    Introduction

    The Surge Protector 2 is an evolution of the original LORENTZ Surge Protector. The Surge
    Protector 2 is compatible with more LORENTZ accessories and is faster to install and
    exchange.

    The Surge Protector should be installed where any external sensors may be subject to
    induced voltages from lightening or other high power sources. The Surge Protector 2 is
    installed between the controller and any sensors to reduce the chance of the controller
    being damaged from external voltages.

    Compatibility

    The Surge Protector 2 can be used with any switched, pulse or analogue (4-20 mA) inputs
    sensors including

    • Well Probe Sensor 19-000000


    • Water Sensor 19-000001
    • Float Switch 19-000030
    • Pressure Switch 19-000310
    • Liquid Level (all types e.g. 19-005040)
    • Liquid Pressure Sensor (all types, e.g. 19-004460)
    • Water Meter (all types, e.g. 19-002160)
    • Sun Switch (19-000050)

    All specifications and information are given with good intent, errors are possible and products may be subject to change
    without notice. Pictures may differ from actual products depending on local market requirements and regulations.
    Installation

    The Surge Protector 2 must be installed inside the controller. The small size allows for
    multiple Surge Protectors to be installed to protect all connected inputs.

    The Surge Protector 2 has two wires at the top that connect to the controller and two
    terminals at the bottom that connect to the external switch/sensor. The Surge Protector is
    installed in between the controller terminals and the switch/sensor.

    Correct polarity should be observed when connecting any sensors to the controller. Wrong
    polarity will cause false sensor signals or errors being reported.

    The Surge Protector 2 is polarity safe. We recommend using the red wire* (+) for switched
    connections (closed switch symbol), pulse or 24V+ and the black wire* (-) for com or
    signal.
    *In the example wiring below, red wire is shown as dashed line, black wire as solid line.

    ATTENTION – The Surge Proctector 2 has no inbuilt cable strain relief for the
    terminal connection. Ensure that the cable gland is tightened to provide strain
    relief to the cable.
