Preventing risks of fatal injury from electric shocks
•
Make sure that all regulations applicable at the point of use are complied with.
•
Always make sure that the controller is disconnected from the power supply before
carrying out any work on it.
•
Make sure that the connections of the protective extra-low voltage areas do not get
mixed up with the power supply connections.
•
On completion of installation work, refit the terminal cover and tighten the locking
screw using a screwdriver.
•
Make sure that the electrical connection of the controller can be disconnected from the
mains externally if required.
•
Make sure that all cables are secured by strain relief devices.
•
Use the device only if it is in a fault-free condition.
Preventing risks of fire
•
Install the controller on a non-flammable subsurface.
Preventing risks of injury from burns
•
Carry out installation work on the solar power system only when it has cooled down.
•
The process water can reach very high temperatures. Exercise particular care when
configuring settings on the controller.
•
Take water samples after completion of the settings and check them using a suitable
thermometer.
Preventing damage to property
•
A damaged controller may cause malfunctions in the system as well as damage to its
components. Use the controller only if it is in a fault-free condition.
•
Install the controller with due observance of its protection class. Information about this
can be found in the chapter
Technical Data
from page 46 onwards.
•
Make sure that no moisture gets into the controller.
•
If any moisture gets into the controller, disconnect the controller from the power
supply.
•
Make sure that the maximum permissible ambient temperature is not exceeded.
Information about this can be found in the chapter
Technical Data
from page 46
onwards.
•
Make sure that all components to be connected to the switching outputs are suitable
for an operating voltage of 230 V/50 Hz.
•
When in "manual mode", the system must only ever be operated for a short time and
only for test purposes.
•
Install sensor lines separately from 230 V lines.
