Electrical system

Connect the pump and install the connection cables as described in the "Installation"
section and in accordance with the VDE guidelines and applicable national regulations.
• The pump must be properly protected and earthed.
• Ensure all monitoring devices are connected and have been tested.
• A power supply separator (main switch or DC switch for operation with photovoltaics
systems) must be provided on site!
RISK of fatal injury due to electrocution!
Improper electrical connections can lead to fatal
electrical shocks. Electrical connections may only
be carried out by a qualified electrician approved
by the local energy supply company, in accordance
with locally applicable regulations.
Direction of rotation control
The direction of rotation is controlled via the integrated frequency converter. It in-
ternally guarantees correct polarity and the pump automatically rotates in the correct
direction.

Initial commissioning

Check the following prior to initial commissioning:
• The pump was installed and connected correctly.
• Insulation check was carried out.
• For applications in closed pipe systems:
The system has been vented and flushed.
7.2.1. Venting the pump and piping (for closed pipe systems)
• Open all slide valves in the pressure pipe.
• Switch on the power supply (main switch or DC switch, see Section 6.5). Depending
on the available supply voltage (mains operation or solar power supply) the pump now
operates at maximum delivery rate.
The air escapes through the corresponding air vent valves. If air vent valves have not
been installed, check the taps so the air can escape here!
• Once the pump and pipe system have been vented, once again disconnect the pump
from the power supply and close any potentially open taps.
