environments. Where shielding is used, connect
the shield to the chassis via the rear panel ground
screw. Even if noise is not a concern, the load and
remote sense wires should be twisted-pairs to
reduce coupling, which might impact the stability
of the power supply. The sense leads should be
separated from the power leads.

Output Terminals

Background Before connecting the output terminals to the load,
first consider whether voltage sense will be used,
the gauge of the cable wiring and the withstand
voltage of the cables and load.

The output terminals are of two types:
- Two solid bars equipped with M10-size bolt and
nuts for low-voltage output models. (PHU-80,
PHU-200)
- Two solid bars equipped with M6-size bolt and
nuts for high-voltage output models. (PHU-500,
PHU-750, PHU-1000, PHU-1500)

Dangerous voltages. Ensure that the power to the
WARNING instrument is disabled before handling the power
supply output terminals. Failing to do so may lead to
electric shock.
Steps 1. Turn the power off.

2. Remove the output terminal cover. Page 48

3. If necessary, connect the chassis Page 36
ground terminal to either the
positive or negative terminal. See
the grounding chapter for details.
