the housing:
• Loosen the 4 cover fixing screws
• Fasten the switchgear to the wall with the dowels
and screws.

7.2 Electrical connection

DANGER! Risk of fatal injury!
Improper electrical connections can lead to fatal
electrical shocks.
Only allow the electrical connection to be made
by an electrician approved by the local electric-
ity supply company and in accordance with the
local regulations in force.
• The type of mains, current and voltage of the
mains connection must match the details on the
type plate of the pump/motor.
• Mains requirements:

• Mains side fuse protection:
• max. 16 A, slow-blow (with premounted cable
1.5 mm² and 16 A CEE/shock-proof plug)
• max. 25 A, slow-blow (with premounted cable
4.0 mm² and 32 A CEE plugor with direct power
supply to terminal)
• To increase operating safety, it is essential that a
circuit breaker (which disconnects all power leads)
with K characteristic is used. Provide residual-cur-
Installation and operating instructions Wilo-Control EC-Drain LS2
NOTE: 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 operation on a mains power supply with a sys-
tem impedance of Z
of max. ... Ohm (column 2) for a maximum number
of ... switchings (column 3).
If the mains impedance and the number of switch-
ing operations per hour is greater than the values
given in the table, because of the unfavourable
mains connections, the switchgear with the pump
may lead to temporary voltage drops and also to
disturbing voltage fluctuations, or flickering.
Therefore, measures may be necessary before the
switchgear with pump can be operated correctly
on this connection. The necessary information
must be obtained from the local electricity supply
company and the manufacturer.

• Feed the ends of the pump cable through the
cable screw fittings and cable inlets and wire them
according to the markings on the terminal strip.
• Earth the pump/installation according to regula-
tions.
