 For hazardous locations special restrictions apply, see Appendix E,

Standards.

• Never connect the equipment to the mains power supply during installation

work.

• Take extreme care when connecting the system to the mains power supply.

Injury or death can be the result of incorrect procedures.

• Ensure that all personnel operating or maintaining the installation know the

exact location of and how to operate the equipment isolating safety switch

and the mains power supply isolating switch.

• When the process sub-sections have been checked and a test run has been

performed, a person responsible must check the interlocking chains etc. All

concerned personnel must be fully informed regarding test runs to be

performed.

• Process technicians are to be present when testing and operating process

objects.

• Never activate any System Initialization push-button if any uncertainty

exists regarding exactly what occurs within the system during initialization.

ALWAYS CHECK FIRST.

• Remember at all times, that the control system can be controlled from a

remote engineering station, connected at another node via Control

Network.

• Remember, the AC 800M Controller will start automatically when voltage

is applied.

Taking steps to bring the process to a safe state, provides an improved level of

safety when power supplies, communication links or parts of the control system

fail. Such steps may require, for example, the installation of valves or relays that

automatically return to a fail-safe position.
