RUN Output
These terminals are short-circuited during PC operation. Use them to receive
PC RUN signals, for purposes such as emergency stop circuits.
Maximum switching capacity:
250 VAC, 2 A (cos
∅
= 1)
250 VAC, 0.5 A (cos
∅
= 0.4)
24 VDC, 2 A
Note
1. I/O Power Supply Units do not have these terminals.
2. For the C200H-CPU03-E, use a DC power supply provided with reinforced
insulation or double insulation if the EC directives (low-voltage directives)
must be satisfied.

Grounding
To avoid electrical shock, attach a grounded (earth ground) AWG 14 wire (cross-
sectional area of at least 2 mm
2
) to the GR terminal. The resistance to ground
must be less than 100
Ω
. Do not use a wire longer than 20 m. Care must be tak-
en, because ground resistance is affected by environmental conditions such as
soil composition, water content, time of year, and the length of time since the
wire was laid underground.
The Line Ground (LG) terminal is a noise-filtered neutral terminal that does not
normally require grounding. If electrical noise is a problem, however, this termi-
nal should be connected to the Ground (GR) terminal.
PC operation may be adversely affected if the ground wire is shared with other
equipment, or if the ground wire is attached to the metal structure of a building.
