Safety instructions
Certified usage
Only use the device for application cases that are described in the
Hirschmann product information, including this manual. Only operate the
device according to the technical specifications.
Supply voltage
Note: The supply voltage is only connected with the chassis via protective
elements.
Only for device variants with operating voltage type M9:
For the supply voltage to be connected, make sure the following
requirements are met:
The power supply conforms to overvoltage category I or II.
The voltage supply has an easily accessible disconnecting device
(e.g. a switch or a plug). This disconnecting device is clearly
identified so that in the case of an emergency, it is clear which
disconnecting device belongs to which line.
The lines to be connected are voltage-free.
Supply with DC voltage:
A fuse suitable for DC voltage is located in the plus conductor of the
power supply. A fuse is also located in the minus conductor, if this
is not grounded.
Regarding the properties of this fuse: See “General technical data”
on page 40.
Supply with AC voltage:
A fuse is located in the outer conductor of the power supply. A fuse
is also located in the neutral conductor, if this is not grounded.
Regarding the properties of this fuse: See “General technical data”
on page 40.
AC voltage Supply: the wire diameter for the input supply line is at
least 0.75 mm² (North America: AWG18).
DC voltage Supply: the wire diameter for the input supply line is at
least 1 mm² (North America: AWG16).
WARNING
ELECTRIC SHOCK
Ground the device before connecting the power supply.
Only connect a supply voltage as described in the data plate of your device.
