. Device Installation and Connection
Installation
Schematic diagrams and dimensions are provided over the next few pages.
An opening of 92x92mm is necessary for the device casing.The device is to be inserted
from the front and fastened with the lock-on clips provided on delivery.
The wall mount casing can be hung up or pushed under into the mounting slots. It must
then be fastened on with two screws.
CAUTION
The device assembly site should be chosen such that the device is not subject to
any mechanical load or chemical exposure!
Please note that the corresponding protection classes are:
Built-in casing: IP54 for the front end, with IP55 at the front door
Wall-mounted casing: IP65 (when the clamp cover is closed)
Connections
Connection diagrams are provided on the following pages.
Please be aware of the supply voltage indicated on the rating plate at all times.
CAUTION
Input, output, and control lead wires and cables must always be installed sepa-
rated from one another and, above all, separated from high voltage lines!
All input and output wires and cables need to be shielded. The shielding can only be
applied on one side.
Potentiostatic measurement is sensitive to parasitic induction. Be sure to use a special,
double-shielded cable. The membrane sensors are shipped with the cable included.
For Pt100 temperature sensor connection, be sure to use a heavy gauge cable with the
lowest resistance possible.
When connecting to the relays, bear in mind that inductive loads need to be interference-
suppressed. If this is not possible, the device terminal strip relay contacts need to be
provided with an RC-protective circuit. With direct current voltage, the relays or contactor
coil need to be interface-suppressed using a freewheeling diode.
