VersaTools® MTP DA4 and MTP DA8, cont’d
4Output Mute connections — The Output Mute connector provides a way to mute (blank) any or all TP outputs. Each numbered pin of the captive screw connector is assigned to one of the DA’s outputs (pin A is assigned to all DA outputs) (figure 7). When you short and latch a numbered pin or pins to ground, the DA mutes the associated output(s).
Do not tin the power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could be pulled out.
To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

The two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.
TP cable termination
TIA/EIA T 568B wiring standards for all connections.

CAUTION | Power supply voltage polarity is critical. Incorrect |
| voltage polarity can damage the power supply and |
| the MTP DA. Identify the power cord negative lead |
| by the ridges on the side of the cord (figure 8). |
CAUTION | The length of the exposed (stripped) copper wires is |
| important. The ideal length is 0.2" (5 mm). |
Longer bare wires can short together. Shorter wires are not as secure in the captive screw connectors and could be pulled out.
