Warning notes
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Only qualified personnel may open, interfere with or modify the actuators!
Read the documentation on the actuators carefully and fully. If not observed,
dangerous situations might occur
The user must ensure that the actuators meet the requirements of the relevant
application standards
Safety-related applications are only available with Siemens burner controls!
All product-related activities (mounting, settings and maintenance) must be
performed by qualified and authorized personnel
Caution!
Risk of electric shock hazard – to disconnect the actuator from power, it may be
necessary to open more than one switch. Before performing maintenance work,
the actuator must be disconnected from power
The electrical connection between the conduit fittings is not made automatically.
It must be established on installation site
The connecting plate is made of plastic and does not provide earthing of the
conduit fittings. Earthing must be ensured by adequate washers and wire links
All cam switch settings must satisfy the requirements of the relevant application
standards
To provide protection against electric shock hazard, the connecting terminals must
have adequate touch protection. Make certain that non-insulated connections or
wires cannot be touched
Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring is in an orderly state
Fall or shock can adversely affect the safety functions. Such actuators must not be
put into operation even if they do not exhibit any damage
Static charges must be avoided since they can damage the actuator’s electronic
components when touched.
Recommendation:
Use
ESD equipment
Notes on use in North America
Use of flexible conduit including adequate accessories is mandatory
Use of copper wiring is mandatory
All circuits of class 2 must use cables type CL3, CL3R, CL3P or comparable types,
OR
All circuits are wired according to class 1 (electrical light or power circuits)
