Safety Instructions
This symbol indicates passages in the text which you have to pay special
attention to so as to guarantee proper use and preclude any risk.
•The range of applications for this product are industrial processes and controls, where the
overvoltages applied to the product at the connection terminals are limited to values of the
overvoltage category II.
•This device is made and tested according to the valid standards of technics and has left the
factory in a perfect safety state. To keep this state and secure operation without danger, the user
has to observe the saftety and warning hints, contained in this operation manual.
•Assembling and mounting of electrical divices are restricted to be done by skilled electricians!
Skilled electrician is, who can judge the tasks deputed to him and foresee possible dangers, due
to his special education, knowledge and experience and consciousness of the pertinent
standards.
•Mount devices are only allowed to be operated when mounted.
•Finger protection at connection part of mount devices is to be secured when mounting!
•While mounting the device, it must be secured that the requirements, which are asked for the
device in the pertaining standards for safety, are not affected in a negative way, so reducing the
safety of this mount device.
•Mounting and assembling of device needs observation of the specifications of the local Energy
Suppliers.
•Before switching on, make sure that the power and control voltages are not exceeding the values
in accordance with the technical data.
•If it is to be assumed that operation without danger is not further possible, the device must be put
out of operation and secured from unintentional operation! It must be assumed that an operation
without danger is not further possible,
if the device shows damage
if the device stops functioning
after a longer stocking period under unfavourable conditions
after heavy strain during transportation.
•If by a failure or a malfunction of the device, endangering of men or animals or damaging of
facilities are possible, this must be avoided by additional safety measures (end switches,
protection devices and etc.).
•Before opening any cover, the device must be switched voltagefree.
•Hengstler Counters are intended for industrial applications.
•The mounting environment and nearby cabling have an important influence on the EMC (noise
radiation and noise immunity) of the counter. When putting into operation, the EMC of the whole
installation (unit) has to be secured. In particular, the relay outputs are to be protected from high
noise radiation by suitable wiring.
