Connecting To The Water Supply; Installing The Electrical System - Bosch Rexroth RE 07009-MON General Assembly Instructions

RE 07009-MON/11.17 | Assembly Instructions for Hydraulic Power Units
Hose assemblies
CAUTION!
The hose assemblies should be installed such that
– Kinking and tensile load of the hose is avoided during operation,
– The hose is not twisted or turned,
– The outer layer of the hose does not rub off through abrasion or impact,
– The weight of the hose assembly does not cause inadmissible loading.
If a hose assembly becomes detached and there is a risk of whipping, it is
advisable to fit a hose safety catch. If the hose assemblies are equipped with
loosening-resistant fittings, no safety catch is required.

Installing the electrical system

Risk of injury when assembling under voltage!
If you fail to switch off the power supply before assembling the product, you may
suffer injury, destroy the product or damage system components.
Always switch off the power supply to the relevant system component before
f
assembling the product.
6.5.1 Earthing and potential equalization
Hydraulic power units from Bosch Rexroth are supplied with connection for the
external earthing system. Potential equalization within the hydraulic power unit
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 manufacturer when wiring the hydraulic power unit to the machine.
The hydraulic power units must be earthed!
The earthing line and the lines for the potential equalization must have the
minimum cross-section as per VDE regulations and a yellow-green sheath
or labeling.
Before connecting the cables, you should earth the devices that are to be
f
connected and provide for potential equalization via a common equalizing bar.
