POINTS OF CAUTION
■ CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and In-
stallation Category II (transient voltage 2500V). Rein-
forced insulation (input 1 or input 2 to power input: 300V)
is maintained. Prior to installation, check that the insu-
lation class of this unit satisfies the system requirements.
• The equipment must be mounted on a panel surface.
Once mounted on a panel, take appropriate precautions
to prevent operators to be exposed to the terminal block.
• Altitude up to 2000 meters.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. . Failure to observe these re-
quirements may invalidate the CE conformance.
• The actual installation environments such as panel con-
figurations, connected devices and connected wires may
affect the protection level of this unit when it is integrat-
ed in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures* to ensure CE conformity.
* For example, installation of noise filters and clamp fil-
ters for the power source, input and output connected to
the unit, etc.
• In order to enable the operator to turn off the power in-
put immediately, install a switch or a circuit breaker ac-
cording to the relevant requirements in IEC 60947-2 and
properly indicate it.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz,
approx. 3VA (48NV1-1) or 4VA (48NV1-2)
24V DC rating: 24V ±15%,
approx. 1.5W (48NV1-1) or 2W (48NV1-2)

■ GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
• Be sure to put the terminal cover on while the power is
supplied.
■ ENVIRONMENT
• Indoor use.
• If the unit's environmental protection is compromised
(e.g. when multiple units are to be mounted side by side)
when heavy dust or metal particles are present in the air,
install them inside an enclosure with a proper ventila-
tion.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ REQUIREMENTS TO ENSURE IP65
• Observe the designated panel cutout size (31.5 × 138 mm).
• Single mounting only. IP65 is not ensured when the units
are clustered side by side.
• The watertight packing included in the product package
must be placed behind the front cover.
• The mounting bracket must be fastened tightly until they
hit the panel.
• Confirm visually that the packing is not contorted or ex-
cessively run off the edge after installation.
■ WIRING
• 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.
■ TERMINAL BLOCK
• The terminal block is separable in two pieces. Loosen two
screws on top and bottom of the terminal block to sepa-
rate.
• Be sure to turn off the power supply and input signal be-
fore separating the terminal block.
Separable
■ AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
