DANGER due to electrical voltage!
An external voltage is applied to the terminals
for this function. This is also present
at the terminals when the main switch is
switched off!
There is a risk of fatal injury!
The power supply must be disconnected from its
source before commencing any work!
7.2.10 Connection for individual operation (EBM)
and individual fault signal (ESM)
Potential-free contacts are available for external
individual signals per pump.
Insert the core into the threaded cable connection
and secure it. Connect the wires to the terminals
according to the connection diagram.
• Contact type, individual run signal: Normally open
contact
• Contact type, individual fault signal: Normally
closed contact
• Switching capacity: 250 V, 1 A

7.2.11 Connection of an external signalling unit
A 24 V (DC) output is available for direct
connection of an external signalling unit
(e.g. signal lamp).
Insert the core into the threaded cable connection
and secure it. Connect the wires to the terminals
according to the connection diagram.
• Connection load: 24 V (DC), 4 VA
CAUTION!
No external voltage may be applied.
NOTICE
This output function can be selected in
menu 5.67.
7.2.12 Field bus connection "ModBus RTU"
An RS485 interface is available for connecting a
building management system via ModBus RTU
.
Insert the core into the threaded cable connection
and secure it. Connect the wires to the terminals
according to the connection diagram.
CAUTION!
No external voltage may be applied.
NOTICE
To be able to use the function, the values must be
set in menu 2.01 to 2.05.
If the switchgear is at the end of the bus core, the
switchgear must be terminated. To do this, plug in
jumper "J2" (Fig. 2 – 8, pos. 10).
If the bus requires polarisation, jumpers "J3"
and "J4" (Fig. 2 – 8, pos. 10) must be plugged in.

8 Commissioning

WARNING! Risk of fatal injury!
Commissioning by qualified personnel only!
Improper commissioning poses a
risk of fatal injury. Have commissioning per-
formed by qualified personnel only.
DANGER! Risk of fatal injury!
When working on the open switchgear, there is
a danger of electric shock from touching the live
components.
The work must only be carried out by qualified
personnel.
We recommend that the commissioning of the
switchgear be performed by Wilo customer
service.
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 personnel working on or using the switchgear
must have been provided with this manual and
have read and understood it.
In order to prevent damage or serious injury when
commissioning the switchgear, the on-site wiring
must be checked to ensure it has been performed
correctly before activating for the first time, in
particular the earthing. All unit safety devices and
emergency cut-outs must be connected and
inspected to ensure that they are working
properly.
Tighten all connection terminals prior to
commissioning!
NOTICE
In addition to the activities described in these
installation and operating instructions, it is neces-
sary to perform the commissioning measures in
accordance with the installation and operating
instructions of the overall system.
Observe the installation and operating instruc-
tions for products connected to the switchgear
(sensors, pumps) as well as the system
documentation!

8.1 Factory setting

The control system is preset in the factory.
The factory settings can be restored by Wilo cus-
tomer service.

8.2 Activating the switchgear

1. Turn main switch to the "ON" position.
• All LEDs light up for 2 s and the current operat-
ing data and the standby icon appear on the LCD
display.
2. Check the following operating parameters:
• Selection of the mode by adjusting the signal
transmitter (menus 5.06 and 5.08)
• If sensors are used: Adjustment of the measure-
ment range (menu 5.11 or 5.13)
• Pressure thresholds: depending on the signal
transmitter; directly on the pressure switch or in
menus 1.01, 1.04 and 1.05
