Mechanical Installation; Electrical Connection - Labom CI4 Series Operating Instructions Manual

3.1

Mechanical Installation

Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
Before starting operation, check the process connection carefully for leaks under pressure.
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.
