Safety Instructions For Sensor Modules External - Siemens SINAMICS S120 Manual

Encoder system connection
9.11 Sensor Module External SME125
Following encoder systems are connectable to absolute encoders:
• Absolute encoder EnDat 2.1 (with SIN/COS incremental signals 1 Vpp)
• Absolute encoder EnDat 2.2 with order designation EnDat01 or EnDat02
• Absolute encoder SSI (with 5 V supply)
• Absolute encoder SSI (with 5 V supply) with SIN/COS incremental signals 1 Vpp
Neither motor nor encoder data are saved in the SME125.

Safety instructions for Sensor Modules External

The safety instructions listed here also apply to the "General safety instructions" and the "Safety
instructions for Sensor Modules and encoders", especially for SME12☐ Sensor Modules External
(☐ = 0 or 5).
A Sensor Module External SME12☐ is a device belonging to safety class I.
Improper handling of an SME12☐
When an SME12☐ is incorrectly used and handled, protective devices can be disabled, which
means that death or severe injury can occur on touching.
• It is mandatory that you connect a protective conductor with a minimum cross-section of
• In order to ensure degree of protection IP67, close all connections, even connections that
• Before commissioning, always replace the plastic covers of connections X100 to X500 using
• Under no circumstances open the Sensor Modules, as this can mean that they are no longer
• If it appears that the Sensor Module packaging has been damaged by water, do not
NOTICE
Damage caused by connecting a grounded encoder system power supply
The devices can be damaged by connecting encoder systems with grounded encoder system
power supplies.
• Only connect those encoder systems where the power supply is not grounded.
