1General safety instructions
Intended use
The controller is intended for the actuation of dock levellers with a hinged wedge lip or an
extendible lip.
Operating safety is ensured only when the controller is used as intended. No liability is
accepted for any use other than that described in these instructions.
Modifications are allowed only with the consent of the manufacturer. Unauthorised changes
render the manufacturer’s declaration void.
Information on safety
The system must be installed and commissioned by trained, qualified personnel only.
Only qualified electricians may work on the electrical systems. They must be able to assess
the work they are assigned, recognise potential sources of danger, and implement suitable
safety measures.
Installation work must be performed only when all power supplies are disconnected.
Observe the applicable safety and accident prevention regulations and standards.
Covers and protective equipment
Operate only with the system’s own covers and protective equipment.
Make sure that gaskets are properly seated and screw unions adequately tightened.
Replacement parts
Use only original replacement parts.
