specific application to the product.
National and international safety regulations
Verify that the electrical installation meets applicable national and
international safety regulations.
Working voltage
Connect only a working voltage that corresponds to the type plate of
your device.
Make sure the following requirements are met every time you connect
the electrical conductors:
The power supply conforms to over voltage category I or II.
The power supply has an easily accessible disconnecting device
(such as a switch or a plug) which is clearly identified. So in case
of an emergency, it is clear which disconnecting device belongs to
which power supply cable.
The electrical wires are voltage-free.
The power supply is Class 2 compliant.
The working voltage inputs are designed for operation with safety
extra-low voltage. Connect only SELV circuits with voltage
restrictions in line with IEC/EN 60950-1 to the working voltage
connections.
The wire diameter of the power supply cable is at least 0.5 mm²
(North America: AWG20) on the working voltage input.
The wire diameter of the ground conductor is at least 0.5 mm²
(North America: AWG20).
The power supply cables used are permitted for the temperature
range required by the application case.
The power cords are suitable for ambient air temperatures of at
least 167 °F (75 °C). The power cord wires are made of copper.
Turn on the operating voltage for the device only when the following
requirements are fulfilled:
The housing is closed
The terminal block is wired correctly
The terminal block for the operating supply is connected
