Safety Guidelines
General Guideline
CAUTION

Make sure that the voltage input level does not exceed
DC1000V/AC750V.

Make sure the current input level does not exceed 10A.

Do not place any heavy object on the GDM-8261.

Avoid severe impact or rough handling that can lead to
damaging the GDM-8261.

Do not discharge static electricity to the GDM-8261.

Use only mating connectors, not bare wires, for the
terminals.

Do not block or obstruct the cooling fan vent opening.

Do not perform measurement at the source of a
low-voltage installation or at building installations
(Note below).

Do not disassemble the GDM-8261 unless you are
qualified as service personnel.
(Note) EN 61010-1:2010 specifies the measurement categories and
their requirements as follows. The GDM-8261 falls under category
I or II.
 Measurement category IV is for measurement performed at the
source of low-voltage installation.
 Measurement category III is for measurement performed in the
building installation.
 Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
 Measurement category I is for measurements performed on circuits
not directly connected to Mains.
Power Supply
WARNING

AC Input voltage: 100/120/220/240 V AC ±10%,
45Hz to 66Hz / 360Hz to 440Hz

The power supply voltage should not fluctuate more
than 10%.

Connect the protective grounding conductor of the
AC power cord to an earth ground, to avoid electrical
shock.
