7.2 Notes on safety
To eliminate risks during commissioning, observe the notes on safety. See
g 2. Safety.
7.3 Preparation
General requirements
• Clean contaminated parts (material protection). See section g 9.4 Cleaning.
7.4 Step-by-step commissioning
1. Start setup for reference run with limited load and speed.
NOTICE! The mechanical end stops of the linear unit must not be reached
during operation. Otherwise, the linear unit will suffer permanent damage
(material protection).
2. Ensure that the maximum kinetic energy per size specified below is not ex-
ceeded during reference travel. The kinetic energy of the linear unit is calcu-
lated as follows: E = ½ * m * v²
m: moving mass in kg
v: linear speed in m/s
The maximum speed for the reference run is therefore dependent on the moving
mass of the specific application. The moving mass of the linear unit must also be
taken into account.

8 Operation
8.1 Basic requirements
General requirements
• Prevent overheating: Use integrated thermoswitches (material protection).
• Never switch off, modify or bypass safety devices.
In case of malfunctions during operation
• In case of a malfunction that presents an immediate danger for employees or
systems: Switch off product.
8.2 Switching on/off
The product does not feature its own operating control elements. Operation
takes place via a separate control element. See separate manual.

9.1 Notes on safety
To eliminate risks during service, observe the notes on safety. See g 2. Safety.
9.2 Overview
General requirements
• In case of increased wear: Shorten maintenance intervals according to the de-
gree of wear.
• If the linear unit is operated outside the ambient conditions described in these
instructions: Check components once a month for visible changes (oxidation,
contamination, etc.)

9.3 Inspection
9.3.1 General requirements
Use in normal ambient conditions
• The operator is responsible for inspection of the product and the overall sys-
tem.
Use in aggressive ambient conditions
Aggressive ambient conditions include, for example:
• High temperatures
• Heavy accumulation of dirt
• Proximity to grease-dissolving liquids or vapors
Aggressive ambient conditions lead to further requirements for inspection:
• Adapt the inspection interval for seals to the ambient conditions.
NOTICE! Seals age faster under aggressive ambient conditions. Defective
seals will lead to pneumatic leaks and non-compliance with the degree of pro-
tection. Inspect seals more frequently (material protection).
• Enter the adapted inspection intervals in the system-specific maintenance
plan (accident prevention, material protection).
9.3.2 Procedure
Preparation
1. Do not carry out any work on the system during preparation.
2. Close off dangerous areas.
3. Make sure the system or system part is not under pressure or voltage.
4. Protect the system against being restarted.
5. Allow the product and adjacent system parts to cool down.
6. Wear PPE.
Visual inspection
Visually inspect for integrity.
