C.2. Electrical connection
Installation
Before working on the unit, switch off the power supply and secure it
from being switched on again! Check for the absence of power!
Electrical connections may only be made by a specialist and in compli-
ance with the applicable regulations.
Do not use the controller if the housing shows visible damage, for ex-
ample cracks.
Low-voltage cables such as sensor cables must be routed separately
from the mains voltage cables. Feed sensor cables into the left-hand
side of the unit only and mains voltage cables into the right-hand side
only.
The customer must provide an all-pole disconnecting device in the pow-
er supply of the controller e.g. a heating emergency switch.
The cables being connected to the unit must not be stripped by more
than 55 mm and the cable jacket must reach into the housing to the
other side of the strain relief.
Follow the scope of protection according to the German Institut for Standardizations
VDE 0100-702 for the installation of the controller (distance to the scope of protection
0 and 1).
Danger of electric shock due to improper connection!
- Observe VDE and EVU regulations of the energy supply company.
- Install pumps and swimming pools and their scope of protection
according to the German Institut for Standardization VDE 0100-702.
- Install a disconnecting device for the interruption of the power supply
with min 3 mm of contact per pole.
Danger of electric shock due to voltage on the housing!
- A correctly confi gured motor overload switch must be installed.
While doing so, observe the values on the name plate.
- Protect the power supply with a diff erential switch, nominal residual
current I ΔN ≤ 30 mA.
- Only use suitable cables according to regional regulations.
- Adapt the minimum section of the pipe to the motor capacity and the
performance range.
- Provide an emergency stop switch according to DIN EN 809 where
dangerous situations could arise. The operator should make the
decision based on this standard.
