damage to property will result.
WARNING
Avoid the described hazard: otherwise there is danger from electric voltage
that could lead to death or serious physical injury.
For your safety
For safe operation and to avoid personal injury and equipment damage through operator error, always
read these instructions, become familiar with the device, and follow all safety instructions on the
product and in this document, as well as the safety guidelines of Wurm GmbH & Co. KG Elektronische
Systeme. Keep these instructions ready to hand for quick reference and pass them on with the device
if the product is sold.
Wurm GmbH & Co. KG Elektronische Systeme accepts no liability in case of improper use or use for
other than the intended purpose.
Target group
These instructions are intended for "service technicians".
Intended use
The DOC-XP is a measurement and monitoring module for 4 temperatures.
WARNING
Danger to life from electric shock and/or fire!
Switch off the power to the entire plant when
carrying out installation, wiring or removal
work. Otherwise a mains voltage and/or external voltage may still be present even if
the control voltage is switched off. Always remove both power plugs (L and N).
Only qualified electricians are permitted to wire the device.
Use only the correct tools for all work.
Check all wiring after connection.
Take note of the maximum loads on all connections.
Never expose the device to moisture, for example due to condensation or cleaning
agents.
Take the device out of operation if it is faulty or damaged and is therefore
compromising safe operation.
Do not open the device.
Do not attempt to repair the device yourself. If the device requires repairs, send it in
with an exact description of the fault.

Place the device with the upper guide edge on
the top-hat rail.
Then press the device gently downward until it
engages with the fastening safety catch on the
top-hat rail.
For wiring of the data lines, we recommend the use of standard telephone lines 2x2x0.8ø up to
lengths of 100m. The shielding must be grounded in the control cabinet.
For cable lengths from 100m to 400m, shielded lines with braided sheathing should be used.
For sensor extensions, it is recommended that sheathed cable be laid.
