MOUNTING:
Only technicians, who are familiar with the technical terms, warnings, and
instructions in the manual and who are able to follow these, should connect the
module. Should there be any doubt as to the correct handling of the module,
please contact your local distributor or, alternatively,
PR electronics A/S, Lerbakken 10, DK-8410 Rønde, Denmark,
tel: +45 86 37 26 77.
Mounting and connection of the module should comply with national legislation
for mounting of electric materials, i.e. wire cross section, protective fuse, and
location. Descriptions of input/output and supply connections are shown in the
block diagram and side label.
The following apply to fixed hazardous voltages-connected modules:
The max. size of the protective fuse is 10 A and, together with a power
switch, it should be easily accessible and close to the module. The
power switch should be marked with a label telling it will switch off the
voltage to the module.
Production year can be taken from the first 2 digits of the serial number.
CALIBRATION AND ADjUSTMENT:
During calibration and adjustment, the measuring and connection of external
voltages must be carried out according to the specifications of this manual. The
technician must use tools and instruments that are safe to use.
NORMAL OPERATION:
Operators are only allowed to adjust and operate modules that are safely fixed
in panels, etc., thus avoiding the danger of personal injury and damage. This
means there is no electrical shock hazard, and the module is easily accessible.
CLEANING:
When disconnected, the module may be cleaned with a cloth moistened with
distilled water.
LIABILITY:
To the extent the instructions in this manual are not strictly observed, the
custom er cannot advance a demand against PR electronics A/S that would
otherwise exist according to the concluded sales agreement.
