7.4.1 Switchgear mains connection
• Mains connection: 3~400 V + N + PE (L1, L2, L3, N, PE)
• Version: Switchgear with CEE plug pre-installed [in accordance with VDE 0623
in Germany].
• Connect the clockwise rotating field
7.4.2 Connection of the pumps (Fig. 10)
• The pumps are to be wired with the switchgear.
• Undo the housing screws and remove the terminal cover.
• Guide the cable ends of the pump connection line through the threaded cable connections.
• Wire up the cable ends in accordance with the marking on the terminal strips and the spec-
ifications in the wiring diagram:
• Mains connection of the pump 1 to the terminals 27, 28 and 29.
• Mains connection of the pump 2 to the terminals 34, 35 and 36.
• Earth conductor to the remaining PE terminal.
• Connection of the thermal winding contact (WSK) pump 1 to terminals 31 and 32
• Connection of the thermal winding contact (WSK) pump 2 to terminals 38 and 39
7.4.3 Connection of the level sensor (Fig. 11)
• The level sensor must be wired directly with the breakdown barrier.
• Undo the housing screws and remove the cover.
• Feed the cable ends from the level sensor through the cable bushing.
• Wire up the cable ends according to the information in the wiring diagram:
• Brown wire (+) to terminal 23 (+) of the breakdown barrier
• Green wire (-) to terminal 13 (-) of the breakdown barrier
• Blue wire (shield) to PE terminal
• The cable of the breakdown barrier with a signal level of 4-20 mA must be connected to
terminals 25 (+) and 26 (–) in the switchgear using two-wire technology.
• Close the cover of the breakdown barrier and the switchgear, and tighten the housing
screws
DANGER! Danger of explosion!
If a level sensor is used in potentially explosive areas there is a danger of explosion.
• Always use a breakdown barrier (Zener barrier) between the switchgear and the level
sensor in potentially explosive areas.
Observe the safety instructions in the operating instructions for the breakdown bar-
rier.
NOTE:
Observe the correct polarity when connecting the level sensor and the breakdown barrier.
7.4.4 Alarm signal connection
The DrainLift XL system is factory-fitted with an acoustic signal transmitter in the switch-
gear.
An external alarm switchgear, a horn or a flash light can be connected via a potential-free
contact (SSM) in the switchgear. Contact load:
• Permitted minimum: 12 V DC, 10 mA
• Permitted maximum: 250 V AC, 1 A
DANGER! Risk of fatal injury!
There is a danger of electric shock by touching live components when working on the
open switchgear.
This work may only be carried out by qualified personnel.
To connect the alarm signal, switch off the device so that it is voltage-free and secure
it against being switched back on again by unauthorised persons.
Comply with the Installation and operating instructions of the DrainControl PL2 switch-
gear!
• Remove the power plug!
• Open the cover of the switchgear.
• Remove the protective cover from the threaded cable connection.
• Feed the cable through the screwed connection and connect it to the potential-free alarm
contact in accordance with the wiring diagram.
• After connecting the cable for the alarm signal, close the cover of the switchgear and
tighten the threaded cable connection.
• Plug in the mains plug again.
Refer to the operating instructions of the switchgear for a detailed description of the con-
nection options and operation.
