7.1 General

WARNING – All electrical connections must
be performed by qualified experts only.
WARNING – Do not dismantle the
controller while still connected to the
power supply! Before any installation,
maintenance or inspection activities wait
at least five minutes after the power
supply has been disconnected from the
controller!
CAUTION – Installing a SunSwitch is
mandatory for all PS1800 CS-F and all
PS4000 pump systems. Operating without
a SunSwitch can lead to increased wear or
damage to the pump. Such damage is
excluded from the warranty.
CAUTION – Never let the pump run dry.
Dry running will damage the pump and
void the warranty. LORENTZ requires a dry
run protection for every pump system.
For more information on mandatory accessories and their
installation, please refer to "7.7.1.3 Pump Accessories Wir-
ing" on page 28 and "9 Pump Accessories Installation"
on page 54.
Treat the controller as industrial waste when processing the
discarded controller. It is possible that some components
could produce toxic and harmful gas.
