Line-side connection

The SITOP PSU8600 power supply system is designed to be operated on 3-phase AC line
systems (TN or TT line system according to IEC 60364-1) with a rated voltage of 3 AC 400 -
500 V, 50 - 60 Hz or IT line system with a rated voltage of 3 AC 400 - 500 V, 50 - 60 Hz.
NOTICE
Carefully comply with country-specific regulations relating to the installation.
The line supply is connected using terminals "L1", "L2", "L3" and "PE" of the basic unit, and
must be implemented according to IEC 60364 and EN 50178. A protective device (miniature
circuit-breaker or circuit-breaker) and a disconnection unit for the power supply must be
provided. A ground-fault circuit interrupter is not permissible against indirect contact as the
only protective measure. This applies for the complete line supply protected by the ground-
fault circuit interrupter.
