TECHNICAL REFERENCE MANUAL
●
Please note the characteristics and indicators on the system to avoid fire or electric shocks.
Before connecting the system, please read the corresponding specifications in the product
manual carefully.
●
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.
●

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
