Danger
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 exam
-
ple cracks.
Caution
Low-voltage cables such as temperature sensor cables must be routed
separately from the mains voltage cables. Feed temperature sensor ca
-
bles 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 power
supply of the controller e.g. a heating emergency switch.
Caution
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.
Caution
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).
Caution
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 configured motor overload switch must be installed. While
doing so, observe the values on the name plate.
- Protect the power supply with a differential 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.
