POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2, Meas-
urement Category II (output, transient voltage 2500V)
and Installation Category II (transient voltage 2500V).
Reinforced insulation (signal input or output to power in-
put: 300V) and basic insulation (signal input to output:
300V) are maintained. Prior to installation, check that
the insulation class of this unit satisfies the system re-
quirements.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• 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, connected wires, may af-
fect the protection level of this unit when it is integrated
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 the CE conform-
ity.
• Install lightning surge protectors for those wires connect-
ed to remote locations.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
AC power: Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC power: Rating ±10%, approx. 2W
■GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• 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.
■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.
■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.

• Explanations
Hi and Lo Adjustments are used to set the alarm setpoints.
A 0 – 10V DC is output at the Hi and Lo setpoint monitor
jacks across the COM jack, proportional to the setpoint 0 –
100%.
The Hi and Lo LEDs turn on when the coil for each relay is
energized.
• Examples
For setting the relay to trip above 80% of the full-scale in-
put signal, turn the Hi Adj. until you read 8.0V at the Hi
Setpoint Monitor.
