Electrical Connections Of Filter Options And Accessories; Connection Of The Rs-232 Cable Used For Pqf-Link Software Communication - ABB PQFS Installation, Operation And Maintenance Instructions

6.13 Electrical connections of filter options and accessories

Filter options must be ordered in advance and are cabled in the factory. For these
options, refer to the wiring diagram provided with your filter to identify the electrical
connections if desired. For some accessories however, the customer may have to do the
cabling on site. These accessories include:
The connections of the aforementioned accessories are discussed next.
WARNING: Before cabling any of the circuits discussed below, switch off the
power supply to the filter. When the filter has already been installed on site, this
must be done by opening the protection system located just upstream of the filter
and opening the auxiliary fuse box present in the filter. Wait at least 25 minutes to
allow for the DC capacitors to discharge when the filter has been connected to the
network before. Failure to do so may result in lethal injury or death.

Connection of the RS-232 cable used for PQF-Link software communication

When the PQF-Link software is ordered, it comes with a serial communication cable that
is used to connect the PC's serial port to the filter
On the filter side the cable has to be connected to the rear side of the PQF-Manager of
the 'main' master unit, i.e. the master unit that controls the complete system. This is done
by inserting the plug firmly in the dedicated socket.
rear of the PQF-Manager where the plug has to be inserted. In order to access the rear
side of the PQF-Manager, the filter panel cover has to be removed.
If the connection is only a temporary one (e.g. during commissioning) no special cable
pass through hole has to be made in the cable pass through cover present at the bottom
right side of the filter panel. The top cover can simply be restored without fixing the
screws.
If the connection is a permanent one a cable pass through hole of sufficient diameter has
to be made in the cable pass through cover present at the bottom right side of the filter
panel and the cable has to be guided through. Note however that in this case the
