
Fuse type: T3.15A/250V

Make sure the correct type of fuse is installed
before power up.

To avoid fire, only replace the fuse with the
specified type and rating.

Disconnect the power cord before fuse
replacement.


(Pollution Degree) EN 61010-1 specifies the pollution degrees and
their requirements as follows. The PEL-2000B series falls under
degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.

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
