NOTE
Terminal 1 and the center pin of jack J12 are connected together. Terminal 2 and the
sleeve of jack J12 are connected together.
Use any one of the following ground terminals to make the earth ground connection: 8,
10, 12, 14, 18, 20, 22, 24, or 26. Do NOT use terminal 2 to establish the earth ground
connection; terminal 2 is not directly connected to ground.
There are two standard methods for providing earth grounding to HandPunch units:
• earth grounding all units (see page 10)
• carrying an earth ground to each unit (see page 11)
Earth ground all units when there is a good earth ground source near each unit and/or
when there are very long cable runs between units.
Carry an earth ground to each unit when there are no earth grounds convenient to the
unit and the unit's power supply is floating.
