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-8261A.
 Avoid severe impact or rough handling that can lead to
damaging the GDM-8261A.
 Do not discharge static electricity to the GDM-8261A.
 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-8261A unless you are
qualified as service personnel.
 Make sure that the Sense LO terminal to COM port is
limited to 100Vpk, the Sense HI to Sense LO terminals
are limited to 200Vpk and the COM port to earth is
limited to 500Vpk.
(Note) EN 61010-1:2010 specifies the measurement categories and
their requirements as follows. The GDM-8261A falls under
category II 600V.
 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.
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.
