Installation location
When installing the equipment, make sure that you observe the permis-
sible climatic and temperature conditions in line with the technical data.
If exceptional conditions exist at the installation location, suitable
measures must be taken to protect the equipment. Please look at the
accessories we offer with respect to this.
Install the equipment in a location that is not subject to vibrations.
Do not choose a location near any equipment that generates electro-
magnetic fields (transformers, motors, power lines, magnets, semicon-
ductor actuators, high-frequency generators and the like).
Use original suppressor accessories to suppress interference contactor
relays located nearby.
Fix the equipment securely even for mobile use.
The equipment must never be operated without being fixed secure-
ly. There would be a risk of it falling over!
Electrical connection
Before connecting the equipment, check whether the rated voltage spec-
ified on the rating plate corresponds to that available at the installation
location.
Wiring must be carried out exclusively by specialists who are familiar
with the valid local rules for setting up power installations rated for up to
1000 volts.
The equipment must be connected to the power supply in line with the
specifications in these operating instructions (see section 3.3). Make
sure that you observe the relevant national regulations and the local
provisions of the utility supplying the power.
Use only shielded cables for sensor and signal lines. In order to avoid
possible earth currents, the shield must be connected on just one side
(to the equipment).
Lay sensor and signal lines at a sufficient distance from live lines, in
separate cable ducts wherever possible.
All cables that are used must be selected in accordance with DIN/VDE
or the relevant national regulations.
Do not disconnect the yellow/green protective earth conductors or those
labelled „PE" at any point.
Wire all power consumers within a complex system, including the protec-
tive earth conductors, in a star connection. Avoid sequential wiring.
Under no circumstances use the HYGROPHIL unit's supply terminals as
a terminal for other loads.
In the case of interference-prone power supplies (thyristor controllers,
frequent switching of large loads, HF generators), we recommend con-
necting an isolating transformer or mains filter on line side.
Install an all-pole switch near the equipment to switch the equipment on
and off.
If there are several units in one system, each should be protected sepa-
rately against short circuits and equipped with a disconnector of its own.
The protection conductor of the explosion-proof gas sampling hose must
be connected to the potential equalization on site.
