USER MANUAL
● The inputs must not, unless otherwise noted (CATx identification), be connected to the main
circuit of category II, III and IV.
● The power cord separates the system from the power supply. Do not block the power cord, since
it has to be accessible for the users.
● DO NOT use the system if equipment covers or shields are removed.
● If you assume the system is damaged, get it examined by authorized personnel only.
● Adverse environmental conditions are Moisture or high humidity Dust, flammable gases, fumes
or dissolver Thunderstorm or thunderstorm conditions (except assembly PNA) Electrostatic
fields, etc.
● The measurement category can be adjusted depending on module configuration.
● Any other use than described above may damage your system and is attended with dangers like
short-circuiting, fire or electric shocks.
● The whole system must not be changed, rebuilt or opened.
● DO NOT operate damaged equipment: Whenever it is possible that the safety protection
features built into this product have been impaired, either through physical damage, excessive
moisture, or any other reason, REMOVE POWER and do not use the product until the safe
operation can be verified by service-trained personnel. If necessary, return the product to
Dewesoft sales and service office for service and repair to ensure that safety features are

● Be careful with voltages >25 VAC or >35 VDC! These voltages are already high enough in order to
get a perilous electric shock by touching the wiring.
● The product heats during operation. Make sure there is adequate ventilation. Ventilation slots
must not be covered!
● Only fuses of the specified type and nominal current may be used. The use of patched fuses is
prohibited.
● Prevent using metal bare wires! Risk of short circuit and fire hazard!
● DO NOT use the system before, during or shortly after a thunderstorm (risk of lightning and high
energy over-voltage). An advanced range of application under certain conditions is allowed with
