1. Use crimp terminals for wiring.
2. Do not connect bare stranded wires directly to terminals.
3. Be sure not to reverse the positive and negative leads when wiring the
power supply terminals.
Supply power to all of the Power Supply Units from the same source.
4. To allow heat to dissipate, always remove any dustproof labels that are on
the top of the Units before you turn ON the power supply.

• To help prevent electrical shock, ground the ground terminal (GR:
with a ground resistance of less than 100 Ω using a 14-gauge wire (mini-
mum cross-sectional area of 2 mm
• The line ground terminal (LG:
noise is a significant source of errors or electrical shocks are a problem,
connect the line ground terminal to the ground terminal and ground both
with a ground resistance of less than 100 Ω.
• To prevent electrical shock, always ground the LG-GR terminals to a
ground resistance of less than 100 Ω if these are connected to each
other.
• The ground wire should not be more than 20 m long.
• Using the same ground line is used together with other equipment, such
as motors and inverters, or connecting the ground line to structural parts
of buildings may actually increase noise and may have a negative affect
on operation.
