Release 08 08/2014
 National and international safety regulations
 Verify that the electrical installation meets local or nationally applicable
safety regulations.
 Grounding the device
Grounding the device is by means of a separate ground connection on the
device.
 Ground the device before connecting any other cables.
 Disconnect the grounding only after disconnecting all other cables.
The overall shield of a connected shielded twisted pair cable is connected
to the ground connector on the front panel as a conductor.
 Working voltage
The working voltage is connected to the chassis through protective
elements exclusively.
 Connect only a working voltage that corresponds to the type plate of
your device.
 Only for device variants featuring working voltage with the character-
istic value K9 or KK:
See “Device name and product code” on page 13.
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 iden-
tified. So in the case of an emergency, it is clear which discon-
necting device belongs to which power supply cable.
 The electrical wires are voltage-free.
 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 40.
 Supply with AC voltage:
A fuse is located in the outer conductor of the power supply.
The neutral conductor is on ground potential. Otherwise, a fuse is
also located in the neutral conductor.
Regarding the properties of this fuse: See “General technical data”
on page 40.
 Supply with AC voltage:
The wire diameter of the power supply cable is at least 0.75 mm²
(North America: AWG18) on the working voltage input.
