Demounting
WARNING
Unexpected movement of components.
Injury due to impacts or crushing.
• Before working on the product, switch off the control and secure it to prevent it
from being switched back on accidentally.
WARNING
Risk of Injury due to Unexpected Movement of Components
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
Demounting the integrated drive EMCS
1. Allow the product to cool down to room temperature.
2. Disconnect electrical installations on the EMCS.
3. Remove EMCS from the mounting kit
4. Observe transport information

Assembly
WARNING
Risk of injury due to unexpected movement of components.
The drive can move freely in the voltage-free state. This can cause unexpected
movements of the connected mechanics and crush parts of the body.
• Bring moving parts of the mechanical system into a safe position.

Tab. 4: Overview of motor mountings (example electric cylinder unit EPCS-BS)
Only loosen screws or threaded pins that are described in the directions in the
instruction manuals.
1. Fasten motor mounting kit, observe instruction manual
2. Fasten the motor without tension.
Connect motor cables only on completion of mounting.

Installation
WARNING
Risk of injury due to electric shock.
• For the electrical power supply with extra-low voltages, use only PELV circuits
that guarantee a reinforced isolation from the mains network.
• Observe IEC 60204-1/EN 60204-1.
Damage to the device due to non-approved potentials at the pins
• Power connection:
• Do not connect pin 3
• Logic connection:
• EMCS-ST is not hot-pluggable. Only after connection of the reference poten-
tials GND/L– [Pin 4/8] can 24 V levels be applied to digital outputs DO1/DO2
[Pin 2/3] or the IO-Link communication signal C/Q [Pin 3].
• The DO1/DO2 [Pin 2/3] digital outputs and the IO-Link C/Q [Pin 3] communi-
cation signal must be disconnected 100 ms before the power supply connec-
tions GND/L– [Pin 4/8] and 24 V DC/L + [Pin 1], e.g. by the interposition of
relay contacts.
• GND and L– connections:
• The Power, GND [Pin 2] and Logic, GND/L– [Pin 4/8] connections must have
the same potential.
•
Connect cables to the [Logic] and [Power] connections of the integrated drive
EMCS-ST.
