Installation
4.1.
Installing the control unit
The idOil-D30 control unit is DIN rail mounted (M36).
Due to its open structure and to prevent electrical shocks, the idOil-D30
control unit must be installed inside a separate enclosure or device
cabinet.
The control unit must be installed in a safe (non-Ex) space.
Read Section General safety instructions before installation.

Sensor installation
idOil sensors can be installed in zone 0 explosive atmospheres. Do not
remove the sensor markings from the cables or sensor frames.
Read Section General safety instructions before installation.
Check the correct installation depth of the sensor in the instructions of the
separator in question.
For example, sensors can be installed suspended from their cable (see
next figure). Leave a sufficient length of the sensor or extension cable
coiled inside the service well, so that you can easily lift the sensor out for
inspection and cleaning.

4.2.1. Installing the idOil-LIQ high liquid level sensor
The sensor is normally in air, and it issues an alarm when the sensing element is
submerged in liquid. The sensor is installed at a suitable height above the standard liquid
level (L) so that the overflow alarm is activated once the liquid level reaches the sensing
element.
Overflow is possible in the following cases, for example:
