4.3.2 Safety notes for electrical equipment used in industrial

plants with a 400 V AC voltage

WARNING: Dangerous contact voltage

The electrical power-level terminals for the 400 V AC area and connected machines

refer to equipment used in industrial plants. During operation, this equipment has

dangerous, live, moving or rotating parts. These can therefore cause considerable

damage to health or equipment, e.g., due to the unauthorized removal of protective

covers or inadequate maintenance.

– Only qualified personnel may work on the power-level terminals or system (for

the definition, see Section 4.3.1 on page 17).

– When working on the power-level terminals and the system, you must always

keep the operating instructions and other items of product documentation to

hand and observe the information therein.

– It is prohibited for unqualified personnel to work on the power-level terminals,

on the machine or in their vicinity.

The instructions given in the terminal-specific data sheets must be followed

during installation and startup.

The notes on the procedures and the circuit details presented in the terminal-spe-

cific data sheets should be understood in a general sense and the relevant applica-

tion should be tested to see if they apply.

Phoenix Contact cannot guarantee the suitability of the procedures or the circuit

suggestions described for the relevant application.

4.3.3 Installation instructions and notes for low voltage terminals

WARNING: Dangerous contact voltage

Please note that there are dangerous contact voltages when switching circuits that

do meet SELV requirements.

Connecting and disconnecting the terminals for the 120 V AC and 230 V AC voltage

areas is only permitted if the power supply is disconnected.

When working on the terminals and wiring, always switch off the supply voltage and

ensure it cannot be switched on again.

WARNING: Dangerous contact voltage in the event of ground faults

(e.g., because the FI circuit breaker has not tripped or the star point connection is

"free")

Inline terminals for the 120 V AC and 230 V AC voltage areas should only be oper-

ated in grounded AC voltage networks (AC networks).
