SafetyPrecautions
3) Cable used for connection to power source, must have a cross section of 1mm or greater. These wires
should have insulations capacity made of at least 1.5kV.
2) To reduce electro magnetic interference, use wire with adequate rating and twists of the same of
equal size shall be made with shortest connection.
1) To prevent the risk of electric shock power supply to the equipment must be kept OFF while doing the
wiring arrangement. Do not touch the terminals while power is being supplied.
4) A better anti-noise effect can be expected by using standard power supply cable for
the instrument.
WarningGuidelines

3) The equipment in its installed state must not come in close proximity to any heating source,
caustic vapors, oils steam, or other unwanted process by products.
4) Use the specified size of crimp terminal (M3.5 screws) to wire the terminal block. Tightening the
screws on the terminal block using the tightening torque of the range of 1.2 N.m.
5) Do not connect anything to unused terminals.
Maintenance
1) The equipment should be cleaned regularly to avoid blockage of ventilating parts.
2) Clean the equipment with a clean soft cloth. Do not use isopropyl alcohol or any other cleaning agent.
