5 Electrical connection
LWARNING
Device is live
Incorrect connection may result in injury or death.
‣The electrical connection may be performed only by an electrical technician.
‣The electrical technician must have read and understood these Operating Instructions
and must follow the instructions contained therein.
‣Prior to commencing connection work, ensure that no voltage is present on any cable.
5.1 Wiring
LWARNING
Risk of electric shock!
‣At the supply point, the power supply must be isolated from dangerous live cables by
double or reinforced insulation in the case of devices with a 24 V power supply.
NOTICE
The device does not have a power switch
‣The customer must provide a protected circuit breaker in the vicinity of the device.
‣The circuit breaker must be a switch or power switch, and you must label it as the
circuit breaker for the device.
The electrical connection of the transmitter depends on the sensor:
• If you are using the membrane-covered sensor CCS140 / 141 / 240 / 241 or the open
sensor 963, follow the instructions and illustrations in the "Electrical connection, version
1" section.
• If you are using the total chlorine sensor CCS120, follow the instructions and
illustrations in the "Electrical connection, version 2" section.
5.2 Electrical connection, version 1
The wiring diagram shows the connections of a device equipped with all the options. The
connection of the sensors to the various measuring cables is explained in more detail in
the "Measuring cables and sensor connection" section.
