2.1 - 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.
2.2 - Receipt and Unpacking
Unpack the module without damaging it. 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.
2.3 - Environment

All devices fall under Installation Category II, Pollution Degree 1, and Insulation Class II.
2.4 - Mounting
Only technicians who are familiar with the technical terms, warnings, and instruc tions in
the manual and who are able to follow these should connect the device.
Should there be any doubt as to the correct handling of the device, please contact your
local distributor or, alternatively, Mounting and connection of the device 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 devices:
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 device. The power switch should be
marked with a label indicating that it will switch off the volt age to the device.
Year of manufacture can be taken from the first two digits in the serial number.
