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.
