POINTS OF CAUTION
■ 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 AC, 47 – 66 Hz, <8VA
110 – 240V DC rating: 99 – 264V DC, <4W
■ GENERAL PRECAUTION
Before you remove or mount the unit, turn off the power
supply and input signal for safety.
■ ENVIRONMENT
•Indoor use
•Do not install the unit where it is directly exposed to rain,
water droplets or sunlight.
•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 apply physical impact to the unit.
•Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 90% RH in
order to ensure adequate life span and operation.
Hole
Panel
Gasket
■ WIRING
•Wiring to the unit must be conducted by qualified service
personnel.
•Do not install cables (power supply, input and output)
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 supplied, however, a warm up for 30 minutes is required for
satisfying complete performance described in the data
sheet.
•Altitude up to 2000 meters
• The equipment must be mounted inside a panel.
LIGHTNING SURGE PROTECTION
In order to protect the unit from lightning surges entering
through signal and power supply cables, use of appropriate

ERROR DIAGNOSTICS
Firmware destroyed
Calibration data destroyed
System parameters destroyed
System parameters stored in the device are destroyed, often due to excessive noise interference.

Energy reading data destroyed
Energy reading data stored in the device are destroyed, often due to excessive noise interference.
Average (demand) data destroyed
Average (demand) data stored in the device are destroyed, often due to
excessive noise interference.
Statistical data destroyed
Statistical data (e.g. MAX/MIN values) stored in the device are destroyed,
often due to excessive noise interference.

WHAT TO DO
Repair at the factory
Repair at the factory
Initialize the system parameters and set
them up again.
Go to SETTINGS ➝ MAINTE ➝ ALL CLEAR
➝ YES
Reset the energy readings (all energy and
time count) to zero.
Go to RESET ➝ ENERGY
Reset the average readings to zero.
Go to RESET ➝ DEMAND
Reset the statistical data to zero.
Go to RESET ➝ MAX/MIN
‘OL’ followed by a space and alphabets means an input overload error. Each alphabet indicates a particular input error if
there are more than one digit of alphabets.

ERROR DIAGNOSTICS
Either U1 or I1 (selectable) input is lost or the input line frequency is out
of measurable range (45 – 65 Hz).
Either of the current inputs is overload (120% or more of the rating).
Either of the voltage inputs is overload (120% or more of the rating).
WHAT TO DO
Check the input signals/wiring.
Check the input signals.
Check the input signals.
