5.3 Mechanical mounting

The max. torque depends on the mounting point (e.g. material and shape). If
you have any questions, please contact our application consultant.
EN
For contact details see chapter 1 "General information" or the back page of
the operating instructions.
1. Seal the sealing faces.
2. At the mounting point, screw the pressure transmitter in hand-tight.
▶
When screwing in, do not tilt the threads.
3. Tighten with a torque spanner using the spanner flats. The correct torque depends on
the dimensions of the process connection and the gasket used (form/material).

5.4 Electrical connection

For the electrical connection of a CPT62I0 to the model CPH62I0 hand-held pressure
indicator, proceed as follows:
1. To connect or change the reference pressure sensor, switch off the CPH62I0.
2. Connect the hand-held pressure indicator and the pressure sensor to each other
electrically using a separate sensor connection cable. Use the 7-pin plug contact on
the pressure sensor for this.
3. Connect the 7-pin connector to the reference pressure sensor in accordance with the
orientation guide and secure it through the connection sleeve. Turn the connection
sleeve clockwise without much force.
4. Connect the 6-pin M-DIN connector to the hand-held on CH1 or CH2 in accordance
with the orientation guide.
When connecting the sensor connection cable to the hand-held, the pressure sensor's
connector might not locate properly in the socket. In this event you should try holding the
connector by the bend protection, rather than by the connector sleeve.
▶
Connect the connector without tilt the threads.
⇒
If the connector is positioned correctly, it can be plugged in without any significant
effort.
▶
When removing the pressure sensor, do not pull on the sensor connection cable, but
only on the connector sleeve.
The voltage supply is made via the model CPH62I0 hand-held pressure
indicator.
