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 .
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 .
SAFETY INSTRuCTIONS
DEFINITIONS:
Hazardous voltages have been defined as the ranges: 75 to 1500 Volt DC, and
50 to 1000 Volt AC .
Technicians are qualified persons educated or trained to mount, operate, and
also troubleshoot technically correct and in accordance with safety regulations .
Operators, being familiar with the contents of this manual, adjust and operate the
knobs or potentiometers during normal operation .
RECEIpT AND uNpACKING:
Unpack the module without damaging it and make sure that the manual always
follows the module and is always available . The packing should always follow the
module until this has been permanently mounted .
Check at the receipt of the module whether the type corresponds to the one
ordered .
ENVIRONMENT:
Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock,
as well as rain and heavy moisture . If necessary, heating in excess of the stated
limits for ambient temperatures should be avoided by way of ventilation .
All modules fall under Installation Category II, Pollution Degree 1, and Insulation
Class II .
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
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 .
