PCR-LE2 series
The maximum current that the PCR-LE2 Series can generate varies
depending on the model. It also varies depending on the PCR-LE2
Series’ voltage mode, load type, and status. Ensure that the output
power capacity is sufficient for the load capacity. The maximum
output currents (in AC mode—AC rms, with an output voltage of 1
V to 100 V or 2 V to 200 V, and with a load power factor of 0.8 to 1)
for the different models are shown in the table.

- DESCRIPTION -
When the POWER switch is on, even if the output is off, a dan-
gerous voltage exists between the output terminal (L/N or U/V/W/
N) and the chassis (G-ground). To eliminate the voltage between
the output terminal and the chassis, connect N and G of the OUT
-
PUT terminal block.
Connecting to the OUTPUT terminal block
We recommend that you run the load wires alongside each other
and tie them together at several points with cable ties. Connect be-
tween the output terminal and load with the shortest wires possible.
Preparing wires
Use noncombustible wires that have diameters that correspond to
the output current to connect to the load.

* Excerpt from Japanese laws related to electrical equipment.
The values vary depending on conditions such as the wire covering
(insulator), the wire material (allowable temperature), and whether
there are multiple cores in the cable. For cables other than those
specified in this table, consult with a qualified engineer.
WARNING
Risk of electric shock. Before you connect cables to
the OUTPUT terminal block, be sure to turn the POWER
switch off, and then turn off the switchboard.
- Note -
The L and N terminals of the OUTPUT terminal block are isolated
from the input power supply. The polarity does not constitute a
problem in terms of safety. The polarity matters in synchro mode
(in which the product is synchronized with the input power sup
-
ply) and DC mode, so check the polarity of the load before you
connect it to the product. You can use either L or N to ground the
product.
In DC mode and AC+DC mode, N is the reference. When N has
a positive polarity, L is positive electric potential. When N has a
negative polarity, L is negative electric potential.
