Electrical Connection

Warning
Note
SP190-H/DIL-EX2 T* with weather protection cover: the junction box is mounted on the outside of the
sample probe enclosure, underneath the elbow-shaped bottom part of the probe. SP190-H/DIL-EX2 T*
without weather protection cover: the junction box is not fixed, it is a loose wired junction box.
The wiring plan is inside the lid of the junction box. Two separate cord grips are available for the mains
and the signal cable.
Please follow these steps to connect the equipment:
• Remove the lid of the junction box.
• Insert the power cord through the cord grip M20. Connect the mains cable to the appropriate
terminals as shown below.
Insert the signal cable through the other cord grip M16 and connect it to the appropriate terminals
•
as shown in the wiring below.
Tighten both cord grips to secure the inserted cables and prevent cable pull out.
•
If you don't use a signal cable, the cord grip M16 needs to be closed with a blank plug (not
•
included).
• Screw lid back on.

Wrong supply voltage can destroy the device! When connecting the
equipment, make sure that the supply voltage is identical with the
information provided on the model type plate.
Setting up of electrical power installations must be conform to the
requirements of IEC 364 (DIN VDE 0100) 'Regulations on the
Installation of Power Circuits with Nominal Voltages below 1000V',
and must be in compliance with all relevant regulations and
standards.
We recommend the use of temperature resistant cable! A main
switch needs to be provided externally! The main circuit must be
equipped with a fuse corresponding to the nominal current (over
current protection); for electrical details see technical data. We
recommend to use a low temperature alarm at all times. In case of
an alarm the gas flow will be blocked, and the components
downstream of the probe will be protected.
