Caution!
Observe the accident prevention regulations applicable to the system, such as
BGV A 3 "Electrical Systems and Equipment" during installation, commissioning,
maintenance and troubleshooting.
Caution!
Clean soiled contacts using oil-free compressed air or spirit and a lint-free cloth.
Material damage due to electrostatic charging!
Observe the safety measures according to DIN EN 61340-51/-3 in order to pre-
vent electrostatic discharging!
The original packaging protects against any electrostatic discharge.
Only transport the device in its original packaging
During assembly observe all regulations for protection against electrostatic dis-
charges.
Electrical connection!
Install the electrical lines in accordance with the respectively applicable local reg-
ulations (VDE 0100 in Germany).
Lay the measuring lines separately from the power lines.
Produce a connection between the protective ground connection (in the respec-
tive device carrier) and a protective ground.
The cable shielding belongs to the measurement earth.
The effects of interference fields can be prevented through use of twisted and
screened measuring lines.
The respective connection diagrams / connection designs for the devices apply.
Explosion protection!
This device (the version with the Makrolon housing) is suitable for operation in
Explosion Zone 22 with the lid closed (where an explosive atmosphere may arise
due to electrically conductive dusts).
Prior to opening the device, one must ensure that there are no explosive ambient
conditions, such as dust formation.
The special regulations governing operation in an Ex-area must be observed.
Blowing of a fuse!
First determine the causes for the failure and remove them.
Only use fuses which have the same specification as the original type as a re-
placement.
Repaired fuses or short circuiting are not permissible.
