User levels
Operation and parameterisation of the switchgear
is protected by a three-stage security system.
After the user level is selected and the corre
-
sponding password is entered (user symbol on
main screen or INTERACTION->HMI->LOGIN), the
system is released on the relevant user level.
User 1 (standard user – no login):
The display of almost all menu items is released in
this level (typical: local user, e.g. building care
-
taker). Parameter input is limited.
User 2:
The display of almost all menu items is released in
this level (typical: operator). Parameter input is
possible with almost no limitations.
The password for this user level is 2222.
The other user levels are reserved for Wilo.

7 Installation and electrical connection
Installation and electrical connection must be
carried out in accordance with local regulations
and only by qualified personnel.
WARNING! Risk of personal injury!
Existing accident prevention regulations must
be adhered to.
Warning! Danger of electric shock!
Danger due to electrical current must be elimi
-
nated.
Local directives or general directives [e.g. IEC,
VDE etc.] and instructions from local energy
supply companies must be adhered to.
7.1 Installation
• Wall fixation, WM (wall mounted): For pressure-
boosting systems, the WM switchgears are
mounted on the compact unit. If the wall device
should be mounted separately from the compact
unit, this is done using 4 screws, Ø 8 mm. Suitable
measures should be used to ensure the protection
class.
• Floor model, BM (base mounted): The floor model
is set up free-standing on a level surface (with
sufficient bearing capacity). In the standard ver
-
sion, there is an up-right panel support with a
height of 100 mm for the cable inlet. Other sup
-
ports are available on request.
7.2 Electrical connection
WARNING! Danger of electric shock
Electrical connection must be carried out by an
electrician authorised by the local energy supply
company and in accordance with the applicable
local regulations [e.g. VDE regulations].
Mains connection
Warning! Danger of electric shock!
There is a potentially fatal voltage on the supply
side, even when the main switch is turned off.
• The mains type, current type and voltage of the
mains connection must match the details on the
rating plate of the switchgear.
• Mains requirements:
NOTICE:
In accordance with DIN EN / IEC 61000-3-11 (see
table below), the switchgear and pump with motor
power of ... kW (column 1) are provided for opera
-
tion on a mains power supply with a system
impedance of Z
max
at the house connection of
max. ... ohm (column 2) for a maximum number
of ... connections (column 3).
If the mains impedance and the number of con
-
nections per hour are greater than the values
given in the table, the switchgear with the pump
may lead to temporary voltage drops and also to
disturbing voltage fluctuations (flickering) due to
the unfavourable mains conditions.
Therefore, measures may need to be taken before
the switchgear and the pump can be operated on
this connection as intended. The necessary infor
-
mation must be obtained from the local energy
supply company and the manufacturer.
