advisable to fit a hose safety catch. If the hose assemblies are equipped with
loosening-resistant fittings, no safety catch is required.

Earthing and potential equalization
7.5.1
Drive modules from Bosch Rexroth are supplied with connection for the external
earthing system. Potential equalization within the drive module will only occur if
the electrical wiring of the components is included in the scope of delivery. If this
is not the case, potential equalization must be carried out by the machine manu-
facturer when wiring the drive module to the machine.
The drive modules must be grounded!
The earthing line and the lines for the potential equalization must have the mini-
mum cross-section as per VDE regulations and a yellow-green sheath or labeling.
Before connecting the cables, you should earth the device that is to be con-
f
nected and provide for potential equalization via a common equalizing bar.
laying the power supply and control cables and connecting
7.5.2
the electricity supply
The electrical installation must be performed in accordance with the currently
f
applicable rules of electrical engineering.
You must ensure that the power supply is disconnected and also safeguarded
f
against being switched on unintentionally.
You should prevent this e.g. by using a warning sign to draw attention to
f
works at the electrical system.
Installing the electrical control and monitoring equipment
