3P05-PCR-LE 3
Connecting the Load
For detail of handling the terminal block tray and OUTPUT termi-
nal block, see the PCR-LE series setup guide.
The PCR-LE Series OUTPUT terminal block (not included on the
PCR500LE) is wired after you first pull out the terminal block tray.
The terminal box covers ensure that you don’t touch the unwired
terminals.
WARNING
Risk of electric shock.
• Before you connect cables to the OUTPUT terminal
block, be sure to turn the POWER switch off, and then
remove the power plug from the outlet or turn off the
switchboard.
• Do not use the terminal block with the terminal cover re-
moved.
CAUTION
Risk of malfunction.
• Do not connect the PCR-LE series in a delta wiring configura-
tion.
• If you are grounding the output, make sure that the isolation
voltage does not exceed 300 V.
- Note -
If the neutral point is omitted, there are cases in which it will not be
possible to produce the rated power.
Use noncombustible wires that have diameters that correspond to
the output current to connect to the load.

The values vary depending on conditions such as the wire cov-
ering (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.
