General safety instructions
ENGLISH
Personnel qualification
Assembly, commissioning and operation, dis-
assembly, service (including maintenance
and repair) require basic electrical and me-
chanical knowledge, as well as knowledge of
the appropriate technical terms. In order to
ensure operating safety, these activities may
therefore only be carried out by qualified
technical personnel or an instructed person
under the direction and supervision of quali-
fied personnel.
Qualified personnel are those who are able to
assess the tasks they are commissioned to
perform, identify possible risks and take the
appropriate safety measures due to their pro-
fessional training, knowledge, and experi-
ence as well as their knowledge of the appli-
cable regulations. Qualified personnel must
observe the rules relevant to the subject area.

General safety instructions
ENGLISH
Only operate the Compact System in
grounded networks. Operation in non-
grounded networks (IT network) is not per-
mitted, as clearance and creepage distances
in the system may be overloaded.
Here, protective grounding is the permissible
protective measure in accordance with
EN 50178. The inlet cable to the Compact
System must have a PE wire.
Make sure that there is potential equalization
between the workpiece and tightening spin-
dle, as well as its carrier plate, so that poten-
tial equalization is ensured for all system com-
ponents.
Protect the system from short circuits in the
connector cables with a fuse provided by the
customer.
After switching the device off, wait 10 sec-
onds before turning it back on.
Observe the discharging time (at least 90
seconds after separating the system from the
network) before working on the power supply
connections.
During cleaning
Cover all openings with the appropriate pro-
tective equipment in order to prevent deter-
gents from penetrating the system.
Never use solvents or aggressive detergents.
Only clean the product using a slightly damp,
lint-free cloth. Only use water to do this and,
if necessary, a mild detergent.
Do not use a high-pressure cleaner for clean-
ing.
During maintenance and repair
Perform the prescribed maintenance work at
the intervals specified in the instruction man-
ual.
Make sure that no lines, connectors or com-
ponents are disconnected as long as the sys-
tem is under pressure and voltage. Protect
the system against being switched on.

Motor OFF interface XDN1
Two independent motor OFF circuits are
available:
• Motor OFF circuit 1 (NH1) is implemented
via a contactor installed in the Compact
System. This separates the motor from the
servo amplifier (motor is braked).
• Motor OFF circuit 2 (NH2) prevents the
development of a motor rotating field (mo-
tor is not braked).
Both connections are bridged in the delivery
state.

circuits (NH1 and NH2)
Fig. 8: XDN1
Boundary conditions:
• The maximum cable length for the motor
OFF circuit is 30 m.
• Always design the motor OFF circuits sep-
arately and with potential-free contacts. Do
not mix up the motor OFF circuits under
any circumstances.
• Both motor OFF interfaces must be led
back. If only one is used, the other one
must be provided with a wire jumper.
• If you are only using one motor OFF con-
nection option, we recommend implement-
ing the motor OFF function via motor OFF
circuit NH1 (see Fig. 9, page 72).
CAUTION
Risk of damage to persons and
property!
The emergency OFF interface is no sub-
stitute for an emergency stop facility. It
does not offer functional safety according
to
EN ISO 13849. The user is responsible
for determining the necessity of an emer-
gency OFF, its implementation, and the
risk analysis!
Make sure the emergency OFF equip-
ment is accessible and effective. Re-
lease of the emergency OFF equip-
ment may not result in an
uncontrolled system restart!

The maximum torque at the
bolted connections of the termi-
nals at XDN1 must not exceed
0.3 Nm.
CAUTION
Risk of damage to persons and
property!
The user is obliged to maintain the
system-specific requirements for an
emergency OFF system.
When using external power supply
contactors in superior emergency
OFF circuits, observe the restarting
time of 10 seconds for single switch-
ing and 30 seconds for repeated
switching.
Check that the emergency OFF cir-
cuit is functioning correctly before
commissioning the tightening system.
Observe the local, system-specific
regulations and requirements; proper
use of tools, lifting, and transport
equipment; as well as the relevant
standards, provisions, and accident
prevention regulations.
CAUTION
Risk of damage to persons and prop-
erty!
Dangerous shock currents due to insuffi-
cient PE wire connections!
Protective conductor connections
may not be affected by mechanical,
chemical, or electrochemical influ-
ences. The connection must be per-
manent.
NOTE
The voltage circuits on terminal XDN1
are safely isolated from the power
supply circuits (safe isolation in accor-
dance with EN50178). The require-
ments for safe isolation of electric cir-
cuits must be observed if using the
connection options on this terminal.

Motor OFF protective circuit
1. Cut-out via the internal motor contactors
After a cut-out via the motor contactor, the
motor phases are electromechanically iso-
lated from the power supply.
Fig. 9: Motor OFF circuit 1 (NH1) connection to the Compact System
Motor Off switch directly connected to the
contacts for motor OFF
If the S1 motor breaker switch is actuated,
the motor of the hand-held nutrunner/tighten-
ing spindle will be decelerated by the servo
amplifier and the internal contactor in the
compact system will be opened. This tighten-
ing job abort leads to an error message in the
controller. The error message is automatically
acknowledges once switch S1 is closed
again. Now you can restart the system.

2. Cut-out via the end step
In addition, the motor OFF can be switched
via the end step or along with the cut-out via
the motor contactors (double protection).

Use of the ErgoSpin/CC-ErgoSpin hand-held nutrunner as a stationary tightening
spindle (valid for “ 1. Cut-out via the internal motor contactors” and “ 2. Cut-out via
the end step”)
If the ErgoSpin/CC-ErgoSpin hand-held nut-
runner is used as a stationary tightening spin-
dle, the start switch must be continually actu-
ated.
