LOADING AND INSTALLATION
10.3.2 Connecting to the power supply module
The following figure shows the wiring example of power lines, grounding lines, etc. to the
unit.
* 1: The ERR. terminal turns ON/OFF as described below.
The terminal turns OFF (opens) when the AC power is not input, a CPU module stop error
(including a reset) occurs, or the fuse of the power supply module is blown.
POINT
1. Use the thickest possible (max. 2 mm
2
(14 AWG)) wires for the 100/200 VAC
and 24 VDC power cables. Be sure to twist these wires starting at the connec-
tion terminals. For wiring a terminal block, be sure to use a solderless termi-
nal. To prevent short-circuit due to loosening screws, use the solderless
terminals with insulation sleeves of 0.8 mm (0.03 inch) or less thick. The num-
ber of the solderless terminals to be connected for one terminal block are lim-
ited to 2.
2.The ERR. terminal can not be used as a safety output. In addition, set the cable
for ERR. contact in the control panel and its length to 30m (98.43 ft.) or less.
