Installation GREYHOUND Switch
Release 01 04/2016
Correct usage
Only use the device for those purposes specified in the catalog and in the
technical description. Only operate the device with external devices and
components that are recommended and permitted by the manufacturer.
The proper and safe operation of this product depends on proper handling
during transport, proper storage, assembly and installation, and
conscientious operation and maintenance procedures.
National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Supply voltage
The supply voltage is electrically isolated from the housing.
Every
time you connect the electrical conductors, make sure that the
following requirements are met:
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device
(e.g., a switch or a plug). This disconnecting device is clearly
identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply cable.
The electrical wires are voltage-free.
The ground screw on the back of the device is connected to the
protective conductor.
Supply with AC voltage:
A fuse is located in the outer conductor of the power supply.
The neutral conductor is on ground potential at both voltage inputs.
Otherwise, a fuse is also located in the neutral conductor.
Regarding the properties of this fuse:
See “General technical data” on page 58.
Supply with DC voltage:
A fuse suitable for DC voltage is located in the plus conductor of the
power supply.
The minus conductor is on ground potential. Otherwise, a fuse is
also located in the minus conductor.
Regarding the properties of this fuse:
See “General technical data” on page 58.
Supply with DC voltage: the fuse is suitable for a DC voltage.
If the neutral conductor (AC) or the negative conductor (DC) is not
grounded: there is a fuse in each of the two wires.
Supply with AC voltage:
The wire diameter of the power supply cable is at least 0.75 mm²
(North America: AWG18) on the supply voltage input.
