Contents of this chapter

This chapter contains the safety instructions which you must obey

when you install, operate and do maintenance on the safety functions

General warning tells about conditions, other than those

caused by electricity, which can cause injury or death, or

damage to the equipment.

WARNING!

Electrostatic sensitive devices warning tells you about the risk

of electrostatic discharge which can cause damage to the

equipment.

ATEX/UKEX-certified motor thermal protection

functions

Only qualified specialists are permitted to install, control and maintain

the ATEX/UKEX-certified motor thermal protection functions (see

IEC/EN 60079-14). Obey all safety regulations required with

application of Ex motors in Zone 1/21 (equipment category 2) or Zone

2/22 (equipment category 2 or 3).

Instructions for functional safety circuits
