The Compax3 servo controller series is designed for fixed connection to TN
networks (TN-C, TN-C-S or TN-S). Please note that the line-earth voltage may not
exceed 300VAC.
When grounding the neutral conductor, mains
voltages of up to 480VAC are permitted.
When grounding an external conductor (delta
mains, two-phase mains), mains voltages (external
conductor voltages) of up to 300VAC are
permitted.
Servo controllers which are to be connected to an IT network must be provided
with a separating transformer. Then the Compax3 device is operated locally like in
a TN network. The secondary sided center of the separating transformer must be
grounded and connected to the PE connector of the Compax3.
