2.3.7
Grounding of the DC output
Besides the main purpose of grounding the enclosure, the extra grounding point (item “7”
in
1.8.4) can also be used to ground any the DC terminal poles. Doing so causes a potential
shift on the opposite pole against PE. Because of insulation, there is a max. allowed potential
shift defined for the negative DC terminal pole, which depends on the device model. Refer
to
“1.8.3. Specific technical data“
for details.
When potential shifting a model with 60 V rating, the safety ex-
tra low voltage (SELV) can turn into a protective extra low voltage
(PELV) or leave the safe range. In such a situation, the voltage lev-
els on the DC terminal become hazardous and thus the DC terminal
must be covered.
2.3.8
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 needed,
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 provided
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 pro-
cedure. The screws can be used to
assist in pulling out the module.
