Fuse
WARNING
Fuse type:
100V/120V
T0.1A 250V
230V
T0.08A 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.
Make sure the cause of a fuse blowout is fixed before
fuse replacement.
Cleaning the
GDM-8245
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid into the
GDM-8245.
Do not use chemicals or cleaners containing harsh
material such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free, almost
non-conductive pollution (Note below)
Relative Humidity: < 75%
Altitude: < 2000m
Temperature: 0°C to 50°C (operation)
(Note) EN 61010-1:2001 specifies the pollution degrees and their
requirements as follows. The GDM-8245 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
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.
