Mounting / Installation
Mounting with SN6 socket (depending on identity code)
Corresponding to the order, an SN6 input socket may be
preassembled on the device. This socket must first be removed
in order to facilitate installation in the control panel. For this
purpose, open device as described under Point 4.3.
• By pressing the orange-coloured levers simultaneously,
disconnect connection cable from terminals No. 11 and 12.
• Unscrew SN 6 socket (WAF 22) complete with O-ring.
• After installing the controller in the control panel, the SN6
socket can be re-fitted together with the coaxial cable and
O-ring.
IMPORTANT
Ensure the O-ring is fitted correctly!
• Reconnect cable to terminals 11 and 12.
4.3 Electrical installation
WARNING
• Electrical connection must not be carried out before the device has been installed in the
control panel!
• The supply voltage must be disconnected when removing the device together with the
connection lines!
4.3.1 Electrical installation D2C D (control panel installation)
Terminals are provided at the rear of the device to facilitate electrical connection. The number and type of
terminals depend on the type of device.
Not all devices are equipped with terminal row X1 (left).
Among other things, terminal row X2 (centre) serves the purpose of connecting the measured variable.
The measured variable pH can be connected directly to the terminals with SN6 connectors or, as other
measured variables, via a mA input. The jumper must be connected at terminals 9 and 10 of terminal row
X2 if pH sensors are connected to SN6 connectors or to the terminal without connection of equipotential
bonding!
Terminals rows XR1, XR2 and XR3 (right) serve the purpose of connecting power relays. The supply
voltage connection XP is located at the right bottom. An earthing cable is not necessary.
The connectors XHK are provided for service purposes.
Refer to the terminal connection diagrams for the connection terminals (see Page 38-43).
4.3.2 Electrical installation D2C W (wall mounting)
Opening the housing
• Generally, the device may only be opened by qualified personnel.
• Particular care must be taken before opening the device for the purpose of possible service work to
ensure that no voltage is applied to the device (also not at the terminals XR1-3) and the voltage supply
cannot be switched on while carrying out service work.
• The device should only be opened when it is mounted on a wall or installed in a control panel.
