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 chapter 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.

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!
• 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 and the voltage supply
cannot be switched on while carrying out service work.
• Properly close the device before applying any electrical voltage!
IMPORTANT
Tie together stranded wires with cable ties at a distance of 30 mm from the terminals! If
they work loose in the event of a defect, stranded wires carrying mains voltage must be
prevented from coming in contact with low voltage terminals!
4.3.1 Electrical installation D1C 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 variables pH and redox can be connected directly to the terminals with SN6 connectors or, as
other measured variables, via a mA signal. The jumper must be connected at terminals 9 and 10 of terminal
row X2 if pH or redox probes 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 mains power
connection XP is located at the bottom right. 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 40-51).
