Preparation • The current type and voltage must correspond to the
specifications on the rating plate (6).
• Maximum back-up fuse: 10 A, slow-blow.
• Only operate the pump with sinusoidal AC voltage.
• Note the switching frequency:
- On/off switching operations via mains
voltage ≤ 100/24 h.
- ≤ 20/h for a switching frequency of 1 min.
between switching on/off via mains voltage.
• The electrical connection must be made via a fixed
connecting cable equipped with a connector device or
an all-pole switch with a contact opening width of at
least 3 mm (VDE 0700/Part 1).
• Use a connecting cable with sufficient outer diameter
(e.g. H05VV-F3G1.5) to protect against leaking water
and to ensure strain relief on the threaded cable con
-
nection.
• Use a heat-resistant connecting cable where fluid
temperatures exceed 90 °C.
• Ensure that the connecting cable does not make con
-
tact with either the pipes or the pump.
Mains cable
connection
Installing the mains connection cable (Fig. 3):
1. Standard: 3-core coated cable with brass ferrules
2. Optional: Mains cable with 3-pin connection plug
3. Optional: Wilo-Connector cable (Fig. 3, item b)
• Cable assignment:
1 brown: L
2 blue: N
3 yellow/green: PE (
;)
• Press down the locking button of the 3-pin pump
plug and connect the plug to the plug connection (12)
of the control module until it snaps into place (Fig. 4).
Wilo-Connector
connection
Installing Wilo-Connector
• Disconnect the connecting cable from the power
supply.
• Observe terminal assignment (
; (PE), N, L ).
• Connect and install the Wilo-Connector (Fig. 5a to 5e).
