Description
The inlet-pressure sensor is visible on
the wiring diagram.
-
Note: inlet-pressure switch not
included.
Digital input is visible on the wiring
-
diagram.
The fault light is on if a fault occurs in
the pump.
Note: One fault light for each pump.

pump.
The fault light is on if a fault occurs in
the system.
Note: Phase failure causes no fault
indication.
The operating light is on when the
system is in operation.
An ammeter indicates the current of one
- phase per pump.
Note: One ammeter for each pump.
A voltmeter indicates the mains
voltages between mains phases and
- between the neutral conductor, N, and
the mains phases.
Note: One voltmeter for each pump.
With this option the Control MPC is
prepared for connection, meaning that it
- includes fuses and motor starter. The
pilot pump is visible on the wiring
diagram.
The cabinet door can only be opened if
-
the main switch is in off position.
The main switch for switching off the
neutral conductor is only used in
connection with single-phase motors.

rules for the installation site. As
standard, the main switch does not
switch off the neutral conductor.
Protect the booster system against
phase failure.

Note: A potential-free switch is
available for external monitoring
The panel light is on when the door of
the control cabinet is open.
Panel lights for 50 Hz are in accordance
- with EN 60529/10.91.
Note: The panel light and socket are to
be connected to a separate power
supply.
The transient-voltage protection
- protects the booster system against
high-energy transients.
