(Pollution Degree) EN 61010-1:2010 specifies
pollution degrees and their requirements as
follows.Pollution refers to “addition of foreign
matter, solid, liquid, or gaseous (ionized gases),
that may produce a reduction of dielectric
strength or surface resistivity”. The GPP Series
falls under degree 2.
․Pollution degree 1: No pollution or only dry, non-
conductive pollution occurs. The pollution has no
influence.
․Pollution degree 2: Normally only non-conductive
pollution occurs. Occasionally, however, a
temporary conductivity caused by condensation
must be expected.
․Pollution degree 3: Conductive pollution occurs, or
dry, non-conductive pollution occurs which
becomes conductive due to condensation which is
expected. In such conditions, equipment is
normally protected against exposure to direct
sunlight, precipitation, and full wind pressure, but
neither temperature nor humidity is controlled.
Fuse type: 100V/120V：T12A/250V，
220V/230V：T5A/250V
To prevent fire, replace the fuse only with the
specified type and rating.
Disconnect the power cord before replacing the
fuse.
Make sure the cause of fuse blowout is fixed
before replacing the fuse.
