1 Safety precautions

The explosion-proof APS768x-230V power supply unit is approved for operation in

Zone 1 and Zone 21 hazardous areas.

The explosion-proof APS768x-120V power supply unit is approved for operation in

hazardous areas of Class I, II, III; Division 1; Groups A–G.

Special care must be taken when using weighing systems with the APS768x power

supply unit in hazardous areas. The code of practice is oriented to the "Safe

Distribution" concept drawn up by METTLER TOLEDO.

Competence ▲ The weighing system may only be installed, maintained and repaired by

authorised METTLER TOLEDO service personnel.

▲ The mains supply may only be installed by a specialist authorised by the owner-

operator.

Ex approval ▲ No modifications may be made to the device and no repair work may be

performed on the modules. Any weighing platforms or system modules that are

used must comply with the specifications. Non-compliant equipment jeopardises

the intrinsic safety of the system, cancels the Ex approval and renders any

warranty or product liability claims null and void.

▲ The safety of the weighing system is only guaranteed when the weighing system

is operated, installed and maintained in accordance with the respective instructions.

▲ Also comply with the following:

– the instructions for the system modules,

– the relevant national regulations and standards,

– the applicable statutory requirements for electrical equipment installed in

hazardous areas in the respective country,

– all instructions related to safety issued by the owner.

▲ The explosion-proof weighing system must be checked to ensure compliance

with the safety requirements before being put into service for the first time,

following any service work and at least every 3 years.

Operation ▲ Prevent the build-up of static electricity. Always wear suitable working clothes

when operating or performing service work in a hazardous area.

▲ Do not use protective covers with the devices.

▲ Prevent damage to the system components.

Safety precautions

Guide for installers 22021223F 17/04 5

APS768x

Installation ▲ Only install or perform maintenance work on the weighing system in the

hazardous area if the following conditions are fulfilled:

– the intrinsically safe characteristic values and zone approval of the individual

components are in accord with one another,

– the owner has issued a permit ("spark permit" or "fire permit"),

– the area has been rendered safe and the owner's safety co-ordinator has

confirmed that there is no danger,

– the necessary tools and any required protective clothing are provided (danger

of the build-up of static electricity).

▲ The certification papers (certificates, manufacturer’s declarations) must be present.

▲ Lay cabling securely so that it does not move and effectively protect it against damage.

▲ Only route cables into the housing of the system modules via the suitable gland

and ensure proper seating of the seals.

▲ Use only genuine METTLER TOLEDO accessories and cable assemblies with this

product. Use of anauthorized or counterfeit accessories or cable assemblies may

result in voided warranty, improper or erroneous operation or damage to property

(including the unit) and personal injury.
