7.7 Wiring the Controller

7.7.1 Controllers without pre-wired Plugs

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 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 five 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 PS 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 PS controller" on page 19).

7.7.1.1 Terminal Descriptions

If you use the controller version without pre-wired plugs,
open the housing by unscrewing the four screws at the
bottom cover. After removing the cover the terminal rail will
slide out for easier access. If the controller with prewired
plugs is used, pay attention to chapter "7.7.2 Controllers
with pre-wired Plugs" on page 32. All warnings and
instructions concerning the wiring must be followed for both
controller versions.
