NOTICE
Electrostatic discharge (ESD)!
This product contains electrostatic sensitive
components that can be destroyed by electrostatic
discharge (ESD).
It is essential to observe the safety precautions for
handling ESD-sensitive components
Never touch connector pins without ensuring proper
grounding
Wear a grounded ESD wristband when handling
product connections
NOTICE
Damage to the product due to incorrect wiring!
The incorrect wiring of inputs or outputs can cause
damage to the unit or to peripheral devices.
Comply with the pin layouts and specifications of
the product
Assign only pins or wires that will be used

5.3 Product overview
The connections on the rear panel of the device are
protected by dust protection caps from contamination and
damage.
NOTICE
Contamination or damage may result if the dust
protection caps are missing!
If no dust protection caps are fitted to unused
connections, this may impair the proper functioning of
the contacts or destroy them.
Remove dust protection caps only when connecting
measuring devices or peripherals
If you remove a measuring device or peripheral, re-
attach the dust protection cap to the connection
The type of connections for encoders may
vary depending on the product version.

5.4 Connecting encoders
For encoders with an EnDat 2.2 interface:
If the corresponding encoder input has
already been assigned to an axis in the device
settings, then the encoder is automatically
detected upon restart, and the settings are
adapted. Alternatively, you can assign the
encoder input after you have connected the
encoder.
