1.1 Safety instructions
1.1.1 General information
● Do not attempt to install and operate the components of the electric
drive and control system without first reading all documentation provided
with the product. Read and understand these safety instructions and all
user documentation prior to working with these components. If you do
not have the user documentation for the components, contact our
Rexroth sales representative. Ask for these documents to be sent imme‐
diately to the person or persons responsible for the safe operation of the
components.
● If the supplied documents contain some information you do not under‐
stand, it is absolutely necessary that you ask Rexroth for explanation
before you start working at or with the components.
● If the component is resold, rented and/or passed on to others in any oth‐
er form, these safety instructions must be delivered with the component
in the official language of the user's country.
● Only qualified persons may work with components of the electric drive
and control system or within its proximity.
In terms of this Instruction Manual, qualified persons are those persons
who are familiar with the installation, mounting, commissioning and op‐
eration of the components of the electric drive and control system, as
well as with the hazards this implies, and who possess the qualifications
their work requires. To comply with these qualifications, it is necessary,
among other things,
– to be trained, instructed or authorized to switch electric circuits and
components safely on and off, to ground them and to mark them,
– to be trained or instructed to maintain and use adequate safety
equipment,
– to attend a course of instruction in first aid.
● The technical data, connection and installation conditions of the compo‐
nents are specified in the respective application documentations and
must be followed at all times.
● If the components take the form of hardware, then they must remain in
their original state, in other words, no structural changes are permitted.
It is not permitted to decompile software components or alter source co‐
des.
● Do not mount damaged or faulty components or use them in operation.
● Only use accessories and spare parts approved by Rexroth.
● Follow the safety regulations and requirements of the country in which
the electric components of the electric drive and control system are op‐
erated.
● Proper and correct transport, storage, mounting and installation, as well
as care in operation and maintenance, are prerequisites for optimal and
safe operation of the component.
Improper use of these components, failure to follow the safety instructions in
this document or tampering with the product, including disabling of safety de‐
vices, could result in property damage, injury, electric shock or even death.

1.1.2 Protection against contact with electrical parts and housings
This section concerns components of the electric drive and con‐
trol system with voltages of more than 50 volts.
Contact with parts conducting voltages above 50 volts can cause personal
danger and electric shock. When operating components of the electric drive
and control system, it is unavoidable that some parts of these components
conduct dangerous voltage.
High electrical voltage! Danger to life, risk of injury by electric shock or seri‐
ous injury!
● Only qualified persons are allowed to operate, maintain and/or repair the
components of the electric drive and control system.
● Follow the general installation and safety regulations when working on
power installations.
● Before switching on, the equipment grounding conductor must have
been permanently connected to all electric components in accordance
with the connection diagram.
● Even for brief measurements or tests, operation is only allowed if the
equipment grounding conductor has been permanently connected to the
points of the components provided for this purpose.
● Before accessing electrical parts with voltage potentials higher than
50 V, you must disconnect electric components from the mains or from
the power supply unit. Secure the electric component from reconnec‐
tion.
● With electric components, observe the following aspects:
Always wait 30 minutes after switching off power to allow live capacitors
to discharge before accessing an electric component. Measure the elec‐
trical voltage of live parts before beginning to work to make sure that the
equipment is safe to touch.
● Install the covers and guards provided for this purpose before switching
on.
● Never touch any electrical connection points of the components while
power is turned on.
● Do not remove or plug in connectors when the component has been
powered.
● 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 exam‐
ple 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 according to the table below. With an outer conductor cross sec‐
tion smaller than 10 mm2 (8 AWG), the alternative connection of two
equipment grounding conductors is allowed, each having the same
cross section as the outer conductors.

1.1.3 Battery safety
Batteries consist of active chemicals in a solid housing. Therefore, improper
handling can cause injury or property damage.
Risk of injury by improper handling!
● Do not attempt to reactivate low batteries by heating or other methods
(risk of explosion and cauterization).
● Do not attempt to recharge the batteries as this may cause leakage or
explosion.
● Do not throw batteries into open flames.
● Do not dismantle batteries.
● When replacing the battery/batteries, do not damage the electrical parts
installed in the devices.
● Only use the battery types specified for the product.

Environmental protection and disposal! The batteries contained in
the product are considered dangerous goods during land, air, and
sea transport (risk of explosion) in the sense of the legal regula‐
tions. Dispose of used batteries separately from other waste. Ob‐
serve the national regulations of your country.
1.2 Intended use
This product may only be used for the mentioned applications under the
specified application, ambient and operating conditions.
This product is exclusively intended for use in machines and systems in an
industrial environment. This is to be understood as applications according to
IEC 60204-1 "Safety of machinery, Electric equipment of machines" and
NFPA 79 "Electrical Standard for Industrial Machinery".
Components of the Rexroth IndraDrive Mi system are products of
Category C3 (with restricted distribution) in accordance with
IEC 61800‑3. This Category comprises EMC limit values for line-
based and radiated noise emission. Compliance with this Catego‐
ry (limit values) requires the appropriate measures of interference
suppression to be used in the drive system (e.g., mains filters,
shielding measures).
These components are not provided for use in a public low-volt‐
age mains supplying residential areas. If these components are
used in such a mains, high-frequency interference is to be expec‐
ted. This can require additional measures of interference suppres‐
sion.
