Places with dust, oil fume, conductive dust, corrosive gas and flammable gas;

64

65

Places exposed to high temperature, condensation, wind and rain;

66

67

Places with vibration and shock.

68

69

Electric shock, fire, misoperation will also cause product damage.

70

71

● When machining the screw hole and wiring, do not let iron filings or wire heads fall into the ventilation window of the coupler, which may cause fire, failure, and misoperation.

72

73

2. Precautions for start-up and maintenance

Danger

● Do not touch the terminal when power-on, otherwise it may cause electric shock and misoperation.

78

79

● Please remove and clean the terminal after the power is off. Otherwise, it may cause electric shock when power-on.

80

81

● Please read the manual carefully and confirm the safety before performing program changes, forced output, RUN, STOP and other operations during machine running.

82

83

● Mistakes in operation will damage the machine and cause accidents.

Attention

● Please do not try to decompose and transform the module, otherwise it will cause failure, misoperation, and fire.

88

89

※ For maintenance matters, please contact Wecon Technology Co., Ltd.

90

91

● Please make the loading and unloading of connecting cables such as extension cables after the power supply is turned off, otherwise it will cause faults and wrong action.

92

93

== Maintenance and overhaul ==

Periodic inspection

● Whether the temperature inside the machine has increased abnormally due to other heating elements or direct sunlight;

98

99

● Whether dust or conductive dust has invaded the machine;

100

101

● Whether there are any loose wiring or terminals or other abnormalities.

=== Communication wiring ===

191

192

* Cable recommendation

193

194

EtherCAT bus communication uses STP/FTP cable for network data transmission, without short circuit, dislocation and bad contact.

195

196

The length of the cable between the devices cannot exceed 100 meters. Exceeding 100 meters will cause signal attenuation and affect normal communication.

197

198

It is recommended to use the following specifications of data cables:

199

200

|=**Item**|=**Specifications**

201

|Type of cable|Elastic crossover cable, Category 5E (cat 5e) cable and above

202

|Traverse cross section|AWG26

203

|traverse type|Twisted pair

204

|Line pairs|4 pairs

205

206

* Wiring instructions

207

208

Wiring is carried out according to the radium engraving of the shell, where the IN interface is EtherCAT input port, which is used to connect the EtherCAT master station; The OUT interface is an EtherCAT output port, which is used to connect the later EtherCAT slave station.
