o Input and output terminal strips (when using a M-8IO module)
The safe use of the QNA500 power quality analyzer requires people who install or
handle
it to follow the general safety measures, as well as the warnings documented in
the Instruction Manual.
This power quality analyzer should only be installed and maintained by qualified staff.
5.2.- ASSEMBLY
ENVIRONMENTAL CONDITIONS
This equipment should be used at a temperature of -10ºC to +55ºC to guarantee its optimum operation,
with a relative humidity of 5 to 95%, with no condensation (temperature margin, as stated in the UL
certification). These technical features are guaranteed under internal laboratory tests at -10...55ºC.
CONSIDERATIONS
QNA500 8IO must be installed in a distribution cabinet that protects the analyzer from environmental
contaminating substances, such as oil, humidity, dust and corrosive vapours or other volatile
substances.
The product must be disconnected from the auxiliary power supply sources and from the
measurement in case its safety protection elements have been overridden (visible
damage has been detected). In this case, contact a qualified technical service
representative.
The analyzer has two basic installation methods:
As a compact equipment in a distribution cabinet, installed on the rear PANEL
As a modular equipment, installed on a DIN 46277 rail (EN 50022)
