Safety

All safety instructions must be heeded and observed. Non-observance of safety instructions

may cause damage to life and health of persons, environmental damage and/or extensive

damage to property.

Observing the safety instructions included in the operating instructions will help to avoid

dangers, to operate the installation profitably and to secure the full use of the product.

2.1

Safety summary

The following are recommended safety precautions unrelated to any specific procedures in

this manual and therefore do not appear elsewhere. Personnel must understand and apply

them as appropriate during all phases of operation and maintenance. IN ALL CASES, BE

PRUDENT.

Keep away from live circuits

Do not replace components or make adjustments inside equipment with power turned on.

To avoid injuries, always remove power and discharge and ground a circuit before touching

it. When making electrical connections, the services of a qualified electrician must be

employed. Contact with live electrical circuits can cause serious personal injury or death.

Be sure no circuits are energized during installation, connection or removal of any

electrical cables or lines.

Examine the cabling and housings regularly for damage. Machines with damaged wiring or

control systems must be disconnected from the power line immediately and must not be

operated again until they have been repaired by qualified personnel.

Wear protective clothing

Wear protective clothing (gloves, apron, goggles, etc.) approved for the materials and tools

being used.

Provide adequate ventilation

Provide ventilation to remove heat and noxious odors and to prevent the accumulation of

asphyxiates such as nitrogen gas.

Avoid hot surfaces

Keep hands away from hot surfaces and materials. Contact with hot surfaces or materials

can cause blistering and third degree burns. Wear approved, clean, thermally insulated

gloves when handling these components. Should injury occur; immerse injured area in cold

water and get immediate medical attention.
