WARNING

■ INSULATION CLASS

Insulation class of this unit is as follows.
• Input to power: reinforced insulation (300 V)
• Output to power: reinforced insulation (300 V)
• Input to output: basic insulation (300 V)
(Reinforced insulation (150 V) for UL)
For basic insulation, if insulation failure may result in
equipment, hazardous voltage may result to signal input
and then electric shock may cause.
Prior to installation, prepare supplemental insulation
(equivalent basic insulation) between signal input and ex-
ternal circuits.

■ REGARDING SAFETY

If the equipment is used in a manner not specified by us,
the protection provided by the equipment may be impaired.

■ CONFORMITY WITH EU DIRECTIVES, UK LEGISLATION OR UL

• This equipment is suitable for
- Measurement Category II (output, transient voltage 2500V)
(output, transient voltage 1500 V for UL)
- Installation Category II (transient voltage 2500V)
- Pollution Degree 2
Prior to installation, check that the insulation class of
this unit satisfies the system requirements.
• Altitude up to 2000 meters.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE/UKCA/UL requirements. Failure to observe
these requirements may invalidate the CE/UKCA/UL
conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may affect
the protection level of this unit when it is integrated in a
panel system. The user may have to review the CE/UKCA
requirements in regard to the whole system and employ
additional protective measures* to ensure the CE/UKCA
conformity.
* For example, installation of noise filters and clamp fil-
ters for the power source, input and output connected
to the unit, etc.
• Install lightning surge protectors for those wires connect-
ed to remote locations.

■ SIGNAL INPUT

This terminal is used for signal input.
Do not connect or measure to the circuits including tran-
sient voltage max. 2500V.
Refer to "INPUT SPECIFICATIONS" in detail.

■ OUTPUT TERMINAL

Never use the output terminal under any load that exceeds
the rated values. Otherwise it will impair prescribed per-
formance and cause burning of the equipment itself.

■ WIRING

• For wiring connection, refer to "TERMINAL CONNEC-
TIONS" and wire correctly. Fire, electric shock and fail-
ure cause if wire are incorrectly connected.
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
