The cables are connected as follows:
• Open the control cabinet door.
• Remove the connection cover from the terminals.
• Insert the cables to be connected into the UPS from below or from
the rear. Cables coming from above are routed down next to the
UPS.
• Secure the cables to the respective copper rails by securing the
cable lugs (refer to Figure 14 and 15) using a spanner.
• Secure the protective earth conductors (PE) to the designated
unit frames.
• A shielded battery line may have a favourable effect on the EMC.
For this purpose, connect the shield of the battery line to the
PE connection next to terminal strip X2 using the shortest
possible route.
• Secure the cables for strain relief on the cable clamp rail.
• Check to ensure that the cables are secured correctly and tighten
the fixing bolts if necessary.
• Check the cables for correct polarity and correct phase sequence.
• Remove any cable debris, tools, bolts, etc. from the connection
panel.
• Replace the connection cover.
6.3 Connection of the Control and Signal Lines
The control and signal lines for the remote signalling PCB are
connected to the terminals using a 3 mm screwdriver. Refer to Figure
21 for the connection.
Shielded control and signal lines may have a favourable effect on
the EMC. For this purpose, connect the shield of the lines to the
terminal unit. Additionally, the screen can also be connected to the
PE connection provided on the control unit pivot plate.
