8 Commissioning
DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death
due to electric shock!
• Electrical work must be carried out by a qualified electrician in accord-
ance with the locally applicable regulations.
• If the product is disconnected from the mains, secure it against being
switched on again.
DANGER
Danger to life due to improper commissioning!
Improper commissioning poses danger of death.
• Have commissioning performed by qualified personnel only.
We recommend that commissioning be carried out by WILO customer service.
8.1 Preparatory work
1. Check that all on-site wiring has been performed correctly, in particular the earthing,
prior to the initial start-up.
2. Check all terminals before commissioning and retighten if necessary.
3. In addition to the activities described here, carry out commissioning in accordance with
the installation and operating instructions for the entire system (pressure-boosting
system).
8.2 Factory setting
The control system is preset at the factory.
• If the factory setting is to be restored, contact Wilo customer service.
8.3 Motor direction of rotation
• Switch on each pump briefly in “Manual operation” mode and check whether the direc-
tion of rotation of the pump in mains operation corresponds to the arrow on the pump
housing.
• If the direction of rotation of all pumps in mains operation is wrong, swap any 2 phases
of the mains line.
Control device for fixed speed pumps (SC version)
• If the direction of rotation of only one pump is incorrect in mains operation for direct-
starting motors, swap any 2 phases in the motor terminal box.
• If the direction of rotation of only one pump is incorrect in mains operation for star-
delta-starting motors, swap 4 connections in the motor terminal box. Swap the thread
start and thread end of 2 phases (e.g. V1 for V2 and W1 for W2).
