3. BASIC REQUIREMENTS, SAFETY OF USE
Thesymbolsusedinthemanualhavethefollowingmeaning:
Warning! Potentially hazardous situations. Read before connecting the device! Failure to observe recommendations marked with this symbol can result in heavy personal injuriesanddevicedamage
Caution! Generally useful notes.Read them tomake thedeviceuseeasier.Payattentiontothese noteswhenthedeviceisnotworkingcorrectly. Possible consequences if the information is disregarded!
In terms of safety of use the meter conformstoEN61010-1.
Safety notes:Electrical connections should be made by a person withrequiredlicencestoinstallelectricaldevices.Check the correctness of connections before turningthemeteron.Removalofthemetercoverduringthewarrantyperiodmakesthewarrantynullandvoid.

4. INSTALLATION
4.1. Mounting method
TheN27Pmetercanbeinstalledinmodulardistribu-tionboardsonthe35mmrailbracket.Themeterenclosureismade of plastic and its dimensions are 53 x 110 x 60.5 mm.On the outside of the meter there are screw terminal blo-cks to connect the measurement signals using the leadsupto5.3mm2incrosssection(1A/5A),andupto16mm2
(32 A / 63 A) and the remaining signals using the leadsupto2.5mm2.ThemeterdimensionsareshowninFigure2.
Themeterisintendedforinstallationanduseinindustrialelectromagneticenvironments.The building electrical installation should have a switchor a circuit breaker located near the device, easilyaccessibleandproperlymarked.

Figure 2. Meter dimensions
The meters shall not be installed on the rail in direct contact with other heat emitting devices (e.g. successive N27P meters). Leave the minimum 5-mm space between devices to enable radiation of heat from the enclosure to the ambient air. Otherwise, the temperature in direct vicinity of the meter may exceed the rated operating temperature.
