Electrical Connection - Bosch REXROTH IndraDrive HCS03 Sicherheits- Und Gebrauchshinweise

Mounting
Before mounting the drive components, observe the follow-
ing instructions:
▶ The drive components are designed for control cabinet
mounting.
This excludes drive components with a degree of protec-
tion of at least IP65 in accordance with IEC 60529 (e.g.,
KSM and KMS).
▶ Depending on the site of installation, the control cabinet
must provide sufficient protection against penetration of
foreign objects and ingress of liquids. The degree of pro-
tection must be at least IP54 in accordance with
IEC 60529.
▶ Ensure a safe location for the control cabinet.
▶ For installation and mounting, observe the additional
conditions (see index entries "Data", "Dimensions" and
"Installation" in the Operating Instructions).
WARNING
Personal injury during mounting work!
Danger by falling drive components.
▶ Use personal protective equipment (e.g. safety gloves,
safety shoes) and suitable mounting devices.
▶ When mounting drive components of a machine:
Before starting to work, secure the machine against
movements and unauthorized operation.
▶ Before unfastening mechanical connections, secure the
drive components against falling.

Electrical Connection

For information on the electrical connection of the drive
components, see the Operating Instructions (see index en-
tries "Connection points" and "Equipment grounding con-
ductor").
WARNING
High electrical voltage!
Danger to life, risk of injury by electric shock.
▶ Disconnect the mains power supply before accessing
the drive components and secure the mains power sup-
ply from reconnection.
▶ Before accessing the drive components, wait for the
drive components to discharge.
▶ Always operate drive components with a permanently in-
stalled equipment grounding conductor (= protective
grounding conductor).
In addition, observe the following instructions:
▶ The leakage current of the drive components is greater
▶ Observe the data on the type plate of the drive compo-
▶ Observe the data for the mains connection lines with re-
▶ Establish permanently safe electrical connections.
▶ Keep the control cabinets free from dust, dirt and mois-
▶ Only use original connection accessories by Rexroth.
