Wiring CP1L-EL/EM CPU Units
Section 3-4
Note
(1) Never apply a voltage that exceeds the input voltage for Input Units or the
maximum switching capacity for Output Units.
(2) When the power supply has positive and negative terminals, always wire
them correctly.
(3) When required by EC Low Voltage Directive, use reinforced insulation or
double insulation on the DC power supply connected to DC-power-supply
CPU Units and I/O.
For the DC power supply connected to a DC-power-supply CPU Unit, use
a power supply with a minimum output holding time of 10 ms.
(4) Do not pull on the cables or bend the cables beyond their natural limit. Do-
ing either of these may break the cables.
