2 Safety instructions
2.1 Particularities of these instructions
They cover all units of the type VS2000 Exi. The only difference between the
individual units is the type of supply voltage which is indicated on the type label
of the unit.
They are part of the unit. They contain information about the correct handling of
the product.
Read them before use to familiarise yourself with operating conditions,
installation and operation.
Follow the safety instructions. The operating instructions are intended for
authorised persons according to the EMC and low voltage directives.
2.2 Other important notes
The unit must only be installed, connected and put into operation by a qualified
electrician as during the installation dangerous voltages may be exposed. The
safe function of the unit and the plant is only guaranteed when installation is
correctly carried out.
Be careful when handling the connected unit. This is only allowed by qualified
personnel due to the protection rating IP 20.
The design of the unit corresponds to the protection class II except for the
terminal blocks. Protection against accidental contact (finger-touch to IP 20)
for qualified personnel is only guaranteed if the terminal screw has been
completely screwed in. For this reason the unit must always be installed in a
control cabinet which can only be opened with a tool, for pollution degree 2 and
overvoltage category II.
In case of malfunction of the device or uncertainties always contact the manu-
facturer! Tampering with the device can seriously affect the safety of operators
and machinery. This is not permitted and leads to an exclusion of liability and
warranty.
