Electrical Connection; Devices With Diaphragm Seal - Labom PASCAL Ci4 Series Manual

You can use the device in any mounting position. Normally the transmitter is adjusted for a
vertical mounting position. A different mounting position in combination with a small nomi-
nal range might cause a zero point offset. In this case a zero point adjustment might be
necessary.

Pay attention to the following points regarding electrical connections via cable gland and
terminal block:
 Do not forget to tighten the cable gland after the electrical connection is finalised.
 Press down the spring of spring-operated terminals as far as possible, e.g. with a
screwdriver, before you insert the cable. Otherwise a safe electrical connection
cannot be ensured.

Devices with Diaphragm Seal

Remove the protective cap or protective wrapping from the diaphragm only just before in-
stallation to prevent contamination or damage.
The diaphragm must not be touched. Do not place the device on its diaphragm. Even
small scratches or deformations may negatively influence the zero point or other charac-
teristics of the device.
Pressure transmitter and diaphragm seal are a closed system that must not be separated.
You can find further information about diaphragm seals in the document TA_031 on
