2. Instructions for installation and
connections
Installation:
On the next pages you will find detailed instructions for the installation.
For panel-type meters you have to prepare an opening of 92x92mm. Install the
instrument and fix it with the two mounting clips which were part of the delivery.
You can install instruments in wall-mounting enclosures either by hanging them upon
the center slot or by sliding the slot under a screw, which is an alternative for limited
space. Either way you have to fix it additionally with two screws.
ATTENTION Install the instrument in a place where it is not put under mechanical
or chemical strain!
Mind the protection class:
K 100:
Front IP54, with front door IP55
K 100 W:
IP65 (closed terminal cover)
Connections:
You will find detailed connection diagrams on the following pages.
Before connecting the power supply check the information on the instrument label!
ATTENTION Input, output and control lines must be installed separate from each
other and separate from power lines!
For inputs and outputs use screened lines and connect the screen on one side only.
The pH measurement is interference-sensitive. Use a special screened cable and
over long distances or in humid atmosphere additionally an impedance converter.
For the connection of the temperature sensor Pt100 use a low-resistance cable with a
large diameter.
When using the relays, mind that with inductive loads, interference must be
suppressed. If that is not possible, the relay must be protected at the terminal block in
the K 100 by a resistance-capacitance filter or, in case of direct current, by a free-
wheeling diode.
