Read complete instructions prior to installation and operation of the unit.
WARNING : Risk of electric shock.
SAFETY PRECAUTION
All safety related codifications, symbols and instructions that appear in this operating
manual or on the equipment must be strictly followed to ensure the safety of the operating
personnel as well as the instrument.
If all the equipment is not handled in a manner specified by the manufacturer, it might
impair the protection provided by the equipment.

WARNING GUIDELINES
WARNING : Risk of electric shock.
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.
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.
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.
4. A better anti-noise effect can be expected by using standard power supply cable for the
instrument.

MECHANICAL INSTALLATION GUIDELINES
1) To install the instrument on a DIN rail, raise the clamp at the back of the instrument
and place it on the rail. Now release the clamp, so the instrument fits on the DIN rail.
2) Ensure proper fitting of the instrument by pulling it outwards.
3) To remove the instrument raise the clamp to release it from the DIN rail.
4) The equipment in its installed state must not come in close proximity to any heating
source, caustic vapors, oil steam, or other unwanted process byproducts.
5) Do not connect anything to unused terminals.
Product improvement and upgrade is a constant procedure.
Multispan reserves the right to change specifications without prior notice.Printing and typographical errors reserved.

INSTALLATION GUIDELINES
1. This equipment, being built-in-type, normally becomes a part of main control panel and in
such case the terminals do not remain accessible to the end user after installation
and internal wiring.
2. Do not allow pieces of metal, wire clippings, or fine metallic fillings from installation to
enter the product or else it may lead to a safety hazard that may in turn endanger life or
cause electrical shock to the operator.
3. Circuit breaker or mains switch must be installed between power source and supply
terminal to facilitate power ‘ON’ or ‘OFF’ function. However this mains switch or circuit
breaker must be installed at convenient place normally accessible to the operator.
4. Use and store the instrument within the specified ambient temperature and humidity
ranges as mentioned in this manual.
