Wiring The Controller - Lorentz PS2-150 Manuel D'installation Et De Fonctionnement

7.6 Wiring the Controller

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 minutes after
disconnection to avoid electric shock
hazard.
Before starting to work on the electrical system make sure
that all components are disconnected from the power
source. Do not work on any components when power is
connected or within two minutes after disconnection. The
controller needs time to discharge.
Switch the system on only when all work is completed.
CAUTION – The controller should only be
connected to power after correct wiring or
the controller might get damaged.
CAUTION – Do not install disconnect
switches in the power wires between the
motor and pump controller. Connecting the
motor wires to a switched-on controller
may cause irreparable damage. Such
damage is excluded from the warranty.
CAUTION – Solar-direct systems only – Do
not connect any electrical load to the PV
generator other than the LORENTZ pump
controller. Connection of a battery charger,
active solar tracker controller, electric
fence charger, or other load simultaneous-
ly with LORENTZ PS2 systems may
interfere with the controller and prevent
proper operation.
CAUTION – Measure the voltage before
connecting power to the controller.
Voltage (open circuit) must not exceed the
max. DC input (refer to "Table 2: Technical
data of the PS2 controller" on page 18).
