Fuses
In addition to the main fuse, the devices must be equipped with a S 201 K or S
203 K fuse made by ABB.

Current on the mains PE (leakage current)
This product can cause a direct current in the protective lead. If a residual current
device (RCD) is used for protection in the event of direct or indirect contact, only a
type B (all current sensitive) RCD is permitted on the current supply side of this
product . On the other hand a different protective measure must be taken, such as
for example separation from the environment by double or enforced insulation or
separation from the supply network by a transformer.
Please heed the connection instructions of the RCD supplier.
Mains filters do have high leakage currents due to their internal capacity. An
internal mains filter is usually integrated into the Compax3 servo controllers.
Additional leakage currents are caused by the capacities of the motor cable and of
the motor windings. Due to the high clock frequency of the power output stage, the
leakage currents do have high-frequency components. Please check if the FI
protection switch is suitable for the individual application.
If an external mains filter is used, an additional leakage current will be produced.
The figure of the leakage current depends on the following factors:
Length and properties of the motor cable
Switching frequency
Operation with or without external mains filter
Motor cable with or without shield network
Motor housing grounding (how and where)
Remark:
The leakage current is important with respect to the handling and usage safety of
the device.
A pulsing leakage current occurs if the supply voltage is switched on.
Please note:
The device must be operated with effective grounding connection, which must
comply with the local regulations for high leakage currents (>3.5mA).
Due to the high leakage currents it is not adviseable to operate the servo controller
with an earth leakage circuit breaker.
