11. Insert the required interface cards into the rear of the V400 amplifier mainframe, ensuring it is in the
correct position to mate with its amplifier module and push it home; see Figure 10.
All empty slots must be covered with blanking panels (ASL P/N: RBLANK-V400).
Interface Cards compatible with the M100, M200 and M400 amplifier modules are:
• LSDDC: Dual DC Line Surveillance Interface Card
• SSINT: Standby Surveillance Interface Card
• NSINT: Non-Surveillance Interface Card
• LSIDC: DC Line Surveillance Interface Card

Install 4 x M3 (6 mm) Pozi Pan head fixing screws to bond each interface panel to the amplifier
mainframe chassis and fully tighten the screws. It is important to make sure the screws are fully
tightened to prevent dangerous voltages being present on the panel.
