2.6.2 Safety notes for assembly and maintenance
The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations and
rules for the prevention of accidents apply for the assembly and maintenance of the system. The plant
engineer or the operator is responsible for compliance with these regulations:
The servo drive must only be operated, maintained and/or repaired by personnel trained and
qualified for working on or with electrical devices.
Prevention of accidents, injuries and/or damages:
Additionally secure vertical axes against falling down or lowering after the motor has been
switched off, for example by means of:
Mechanical locking of the vertical axle,
External braking, catching or clamping devices or

Page 12 Safety notes for electrical drives and controllers
Product Manual / Mounting Instructions „Servo drives ARS 2320 FS, ARS 2340 FS and ARS 2360W FS“Version 1.0
Sufficient balancing of the axle
The motor holding brake supplied by default or an external motor holding brake driven by the servo
drive alone is not suitable for personal protection!
Keep the electrical equipment voltage-free using the main switch and protect it from being
switched on again until the DC bus circuit is discharged, in the case of:
Maintenance and repair work
Cleaning
long machine shutdowns
Prior to carrying out maintenance work make sure that the power supply has been turned off,
locked and the DC bus circuit is discharged.
The external or internal brake resistor carries dangerous DC bus voltages during operation of the
servo drive and up to 10 minutes thereafter. Contact may result in death or serious personal injury.
Wait for this time prior to performing any work on the affected connections. Measure the voltages
for your own protection. Contact with these high DC bus circuit voltages may result in death or
serious personal injury.
Be careful during the assembly. During the assembly and also later during operation of the drive,
make sure to prevent drill chips, metal dust or assembly parts (screws, nuts, cable sections) from
falling into the servo drive.
Also make sure that the external power supply of the servo drive (24 V) is switched off.
The DC bus circuit or the mains supply must always be switched off prior to switching off the 24 V
servo drive supply.
Carry out work in the machine area only, if AC and/or DC supplies are switched off. Switched off
output stages or servo drive enablings are no suitable means of locking. In the case of a
malfunction the drive may accidentally be put into action.
This does not apply to drives with the special “Safe Stop” feature in accordance with EN 954-1
CAT 3 or with the “Safe Torque Off” feature in accordance with EN 61800-5-2.
Initial operation must be carried out with idle motors, to prevent mechanical damages for example
due to the wrong direction of rotation.
Electronic devices are never fail-safe. It is the user’s responsibility, in the case an electrical device
fails, to make sure the system is transferred into a secure state.
The servo drive and in particular the brake resistor, externally or internally, can assume high
temperatures, which may cause serious burns.

Safety notes for electrical drives and controllers Page 13
Product Manual / Mounting Instructions „Servo drives ARS 2320 FS, ARS 2340 FS and ARS 2360W FS“Version 1.0
2.6.3 Protection against contact with electrical parts
This section only concerns devices and drive components carrying voltages exceeding 50 V. Contact with
parts carrying voltages of more than 50 V can be dangerous for people and may cause electrical shock.
During operation of electrical devices some parts of these devices will inevitably carry dangerous
voltages.
DANGER!
High electrical voltage!
Danger to life, danger due to electrical shock or serious personal injury!
The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations and
rules for the prevention of accidents apply for the assembly and maintenance of the system. The plant
engineer or the operator is responsible for compliance with these regulations:
Before switching on the device, install the appropriate covers and protections against accidental
contact. Rack-mounted devices must be protected against accidental contact by means of a
housing, for example a switch cabinet. The national regulations for safety/accident prevention must
be complied with!
Always connect the ground conductor of the electrical equipment and devices securely to the
mains supply. Due to the integrated line filter the leakage current exceeds 3.5 mA!
Comply with the minimum copper cross-section for the ground conductor over its entire length (see
for example EN 60800-5-1).
Prior to the initial operation, even for short measuring or testing purposes, always connect the
ground conductor of all electrical devices as per the terminal diagram or connect it to the ground
wire. Otherwise the housing may carry high voltages which can cause electrical shock.
Do not touch electrical connections of the components when switched on.
Prior to accessing electrical parts carrying voltages exceeding 50 Volts, disconnect the device from
the mains or power supply. Protect it from being switched on again.
For the installation the amount of DC bus voltage must be considered, particularly regarding
insulation and protective measures. Ensure proper grounding, wire dimensioning and
corresponding short-circuit protection.
The device comprises a rapid discharge circuit for the DC bus as per EN 60204-1. In certain
device constellations, however, mostly in the case of parallel connection of several servo drives in
the DC bus or in the case of an unconnected brake resistor, this rapid discharge may be rendered
ineffective. The servo drives can carry voltage until up to 10 minutes after being switched off
(residual capacitor charge).

Page 14 Safety notes for electrical drives and controllers
Product Manual / Mounting Instructions „Servo drives ARS 2320 FS, ARS 2340 FS and ARS 2360W FS“Version 1.0
2.6.4 Protection against electrical shock by means of protective extra-low
voltage (PELV)
All connections and terminals with voltages of up to 50 Volts at the servo drive are protective extra-low
voltage, which are designed safe from contact in correspondence with the following standards:
International: IEC 60364-4-41
European countries within the EU: EN 61800-5-1
DANGER!
High electrical voltages due to wrong connections!
Danger to life, risk of injury due to electrical shock!
Only devices and electrical components and wires with a protective extra low voltage (PELV) may be
connected to connectors and terminals with voltages between 0 to 50 Volts.
Only connect voltages and circuits with protection against dangerous voltages. Such protection may be
achieved by means of isolation transformers, safe optocouplers or battery operation.
2.6.5 Protection against dangerous movements
Dangerous movements can be caused by faulty control of connected motors, for different reasons:
Improper or faulty wiring or cabling
Error in handling of components
Error in sensor or transducer
Defective or non-EMC-compliant components
Software error in superordinated control system
These errors can occur directly after switching on the device or after an indeterminate time of operation.
The monitors in the drive components for the most part rule out malfunctions in the connected drives. In
view of personal protection, particularly the danger of personal injury and/or property damage, this may
not be relied on exclusively.
Until the built-in monitors come into effect, faulty drive movements must be taken into account; their
magnitude depends on the type of control and on the operating state.
DANGER!
Dangerous movements!
Danger to life, risk of injury, serious personal injuries or property damage!
For the reasons mentioned above, personal protection must be ensured by means of monitoring or
superordinated measures on the device. These are installed in accordance with the specific data of the
system and a danger and error analysis by the manufacturer. The safety regulations applying to the
system are also taken into consideration. Random movements or other malfunctions may be caused by
switching the safety installations off, by bypassing them or by not activating them.

2.6.6 Protection against contact with hot parts
DANGER!
Housing surfaces may be hot!
Risk of injury! Risk of burning!
Do not touch housing surfaces in the vicinity of heat sources! Danger of burning!
Before accessing devices let them cool down for 10 minutes after switching them off.
Touching hot parts of the equipment such as the housing, which contain heat sinks and resistors,
may cause burns!
2.6.7 Protection during handling and assembly
Handling and assembly of certain parts and components in an unsuitable manner may under adverse
conditions cause injuries.
DANGER!
Risk of injury due to improper handling!
Personal injury due to pinching, shearing, cutting, crushing!
The following general safety notes apply:
Comply with the general setup and safety regulations on handling and assembly.
Use suitable assembly and transportation devices.
Prevent incarcerations and contusions by means of suitable protective measures.
Use suitable tools only. If specified, use special tools.
Use lifting devices and tools appropriately.
If necessary, use suitable protective equipment (for example goggles, protective footwear,
protective gloves).
Do not stand underneath hanging loads.
Remove leaking liquids on the floor immediately to prevent slipping.

typical 5% / 95%
In deviation from the technical motor data, the ARS 2300 FS servo drives have a current derating during
nominal operation. The rated current and the duration of the maximum permissible peak current of the
ARS 2300 FS servo drive depend on several factors.
These factors are:
Output current level (the higher the output current is, the shorter the permissible time will be)
Clock frequency of the power output stage (the higher the clock frequency is, the shorter the
permissible time will be)
Electrical rotational frequency of the motor (speed multiplied by the number of pole pairs) (the
higher the rotational frequency is, the longer the permissible time will be)
