COMMISSIONING
NOTE
• Following a power supply interruption, the
switchgear will automatically start up in the last
operating mode set!
• Observe the installation and operating instruc-
tions for products provided onsite (float switch-
es, connected pumps) as well as the system
documentation!
The "Commissioning" section contains all the
important instructions for operating personnel
on commissioning and operating the switchgear
safely.
Always keep this manual either by the switchgear
or in a place specially reserved for it, where it is
accessible for all operating personnel at all times.
All persons working on or with the switchgear
must have been provided with this operating and
maintenance manual and have read and under-
stood it.
In order to prevent damage or serious injury when
commissioning the switchgear, the following
points must always be observed:
• The switchgear must be installed as described in
the "Installation" section and in accordance with
the applicable national regulations.
• The switchgear must be properly fused and
grounded.
• All unit safety devices and emergency cut-outs
must be connected and inspected to ensure that
they are working properly.
• The switchgear is suitable for use under the spec-
ified operating conditions.

7.1. Level control

The float switches are installed according to the
specifications for the unit and the desired switch-
ing points have been set.

7.2. operation in potentially explosive areas

The switchgear may not be installed or used in
potentially explosive areas.
Connection of monitoring devices and signal
transmitters used within potentially explosive
areas is strictly prohibited.
DANGEr of explosions!
if the switchgear or the connected pump
and signal transmitter are used in potential-
ly explosive areas, there is a danger of fatal
injuries from explosions! the switchgear and
connected pump and signal transmitter must
always be used outside of potentially explo-
sive areas.

7.3. Activating the switchgear

PotENtiALLy fatal danger due to electrical
voltage
All settings need to be made on the switch-
gear components. When performing work on
the uncovered switchgear, there is a risk of
fatal electric shocks occurring. All work must
be carried out by a qualified electrician.
Installation and operating instructions Wilo-Easy Control MS-L 1x4kW
NOTE
Following a power supply interruption, the
switchgear will automatically start up in the last
operating mode set!
The following points must be checked before
activation:
• Check the installation.
• All terminals must be retightened.
• DIP switches correctly set:
• Motor protection (DIP switches 1-5)
• Pump kick (DIP switch 6)
• Buzzer (DIP switch 7)
• Mains voltage pre-selection (DIP switch 8)
• Follow-up time
If corrections are necessary, proceed as in the
section "Electrical connection".
1. Turn main switch to ON position. On switchgears
with a plug, insert this into the corresponding
socket.
2. All LEDs light up for 2 sec.
3. The switchgear is ready for operation.
• The "auto" LED flashes: The switchgear is in
stand-by mode, automatic mode is off.
• The "auto" LED lights up: The switchgear is active,
automatic mode is on. To set the switchgear to
stand-by mode, press the Stop button.
NOTE
If an audible signal is sounded after activation
and all LEDs flash anti-clockwise in turn (in light
sequence), there is a phase fault in the mains
connection. Follow the instructions under "Ro-
tation control".
7.4. rotation control of connected 3-phase current
motors
During factory setting, the switchgear is checked
for clockwise direction of rotation and adjusted to
ensure the direction of rotation is correct.
Observe the wire designations on the wiring
diagram for connecting the switchgear and the
connected pumps.

7.4.1. Checking the direction of rotation

The direction of rotation of the connected pump
can be checked using a brief test run, max. 2
minutes.
1. Press the "Manual" button on the control panel.
2. The pump operates as long as the button is held
down.
BEWArE of damage to the pump
A test run of the connected pump should only
be performed under the permissible operating
conditions. For this, observe the installation
and operating instructions for the pump and
ensure that the required operating conditions
are complied with.
