Figure 2. T400 Housing Terminal Strips - ADTRAN T200 Installation And Maintenance Manual

Inside the housing are two terminal strips (TS1 and
TS2), shown in Figure 2 for connecting to the
network, the CPE, and to an external power source if
used. All wiring connections should be made
according to the label inside the unit cover (Figure 2).
Local power connects to terminals 17 (-48VR) and 35
(-48V) of TS1. A grounding lug is provided for frame
ground connections.
CAUTION
Ensure a frame ground connection is securely
made at ground lug (P1).
