Stop!
No device protection for DC bus voltage surges
In passive axis modules (without 24 V−supply), the charging circuit
can be overloaded through DC bus voltage surges.
Possible consequences:
ƒ Destruction of the device
Protective measures:
ƒ All axis modules in the DC−bus connection should be basically
supplied with a control voltage of 24 V.
ƒ If the total cable length is > 20 m, install an axis module or a capacitor
module directly at the power supply module.
ƒ Design the ±U
G
cables twisted and as short as possible. Ensure
short−circuit−proof routing!
ƒ Cable length (module « module) > 30 cm: install shielded ±U
G
cables.
