Description of Rear Panel Items

[35] Protective conductor terminal

This terminal is for grounding the tester to an earth ground.
For your safety, be sure to ground the tester. For a description of the grounding
method, see section 2.6, “Grounding (Earth)” (Page 2-6).

[36] AC LINE connector

The AC LINE connector is for the AC input power.

[37] SIGNAL I/O connector

The SIGNAL I/O connector is a 14-pin Amphenol connector for the interlock input
signal*, remote control signal for test start/stop, and status output signal. For
details, refer to section 6.3.3, “Interlock Function” (Page 6-24) or section 6.3.2,
“Remote Control through the SIGNAL I/O Connector” (Page 6-21).

• * The

Interlock signal input pin

assignments are different from the old model

TOS5050/5051. Therefore, the 14-pin Amphenol plug that is supplied with the tester
cannot be shared between the new and old models.
