Grounding of the DC output
Grounding one of the DC output poles is permissible, but causes potential shift against PE on the opposite pole.
Because of insulation, there is a max. allowed potential shift defined for the DC output poles, which depends on
the device model. Refer to
“1.8.3. Specific technical data (380/400/480 V models)“
for details.
2.3.9
Installation of an interface module
The optionally obtainable interface modules can be retrofitted by the user and are exchangeable with each other.
The settings for the currently installed module vary and need to be checked and, if necessary, corrected on initial
installation and after module exchange.
•
Common ESD protection procedures apply when inserting or exchanging a module.
•
The device must be switched off before insertion or removal of a module
•
Never insert any other hardware other than an interface module into the slot
•
If no module is in use it’s recommended that the slot cover is mounted in order to avoid internal
dirtying of the device and changes in the air flow (standard models with air-cooling)
Installation steps:
1.
2.
3.
Remove the slot cover. If need-
ed, use a screw driver.
Insert the interface module into the slot. The
shape ensures correct alignment.
When inserting take care that it’s held as
close as possible to a 90° angle to the rear
wall of the device. Use the green PCB which
you can recognize on the open slot as guide.
At the end is a socket for the module.
On the bottom side of the module are two
plastic nibs which must click into the green
board (PCB) so that the module is properly
aligned on the rear wall of the device.
The screws (Torx 8) are pro
-
vided for fixing the module and
should be fully screwed in. After
installation, the module is ready
for use and can be connected.
Removal follows the reverse
procedure. The screws can be
used to assist in pulling out the
module.
