Start-up
29
Proceed as follows to install the SmartFuse 250 on site:
Step Action
1
Clean the interior of the distribution cabinet to remove dirt that could otherwise
accumulate in the vents of the power module during operation.
When necessary, also clean the vents themselves again before insertion (see
page 58).
2
If you only want to install one power module in the distribution cabinet, you can
connect it directly to the supply module using the RS-485 connection cable
.
If you want to install 2 or 3 power modules, you will need to connect the
optionally available three-phase adapter (see page 10) to the supply module
and then connect the individual power modules to the adapter.
It is important to connect a power module to the socket PM-A
, as the supply
module receives its supply voltage via this connection.
3
Connect the supply module using the black/blue connection cable
with the
neutral conductor of the low voltage distribution.
4
Inform yourself about the flow of direction of the load in the low-voltage
distribution and the necessary orientation for inserting the power module into the
fuse holder. A corresponding warning sign can be found on the back of the
power module.
