Bosch Rexroth EFC 3600 - The Scope of Supply

● Under specific conditions, electric drive systems can be operated at mains protected
by residual-current-operated circuit-breakers sensitive to universal current (RCDs/
RCMs).
● Secure built-in devices from penetrating foreign objects and water, as well as from
direct contact, by providing an external housing, for example a control cabinet.
High housing voltage and high leakage current! Danger to life, risk of injury by electric
shock!
● Before switching on and before commissioning, ground or connect the components
of the electric drive and control system to the equipment grounding conductor at the
grounding points.
● Connect the equipment grounding conductor of the components of the electric drive
and control system permanently to the main power supply at all times. The leakage
current is greater than 3.5 mA.
● Establish an equipment grounding connection with a minimum cross section accord‐
ing to the table below. With an outer conductor cross section smaller than 10 mm
2
(8 AWG), the alternative connection of two equipment grounding conductors is al‐
lowed, each having the same cross section as the outer conductors.
