Do not charge, recharge or open in a potentially explosive atmosphere.
In hazardous area only use “Temperature Probe GF5.2” in Connector B.
Connector C (Uo=10V,lo=5mA,Po=50mW,Ci=0,Li=0,Co=100uF,Lo=1000mH),
Connector B (Uo=5V,lo=6mA,Po=7mW,Ci=0,Li=0,Co=100uF,Lo=1000mH)
MAXIMUM NON-HAZARDOUS SUPPLIES:
Connector A - Um=6V Connector B - Um=10.1V
不要在易爆环境下充电或打开设备。
在危险区域只能使用连接在B接头的GF5.2温度探头。
C连接头(Uo=10V,lo=5mA,Po=50mW,Ci=0,Li=0,Co=100uF,Lo=1000mH)
B连接头(Uo=5V,lo=6mA,Po=7mW,Ci=0,Li=0,Co=100uF,Lo=1000mH)
最大安全性连接
A连接头Um=6V B连接头Um=10.1V
The safe area apparatus that is to be connected to the USB Port shall be a Safety
Extra Low Voltage (SELV) or Protective Extra Low Voltage (PELV) circuit.
设备如需要连接USB线，需要在安全低电压或保护低电压的安全区下连接。
Only a Geotechnical Instrument battery pack part number 20087 is permitted as a
replacement. This battery pack shall only be changed in a safe area.
只有Geotechnical公司所配置电池组（编号20087）允许用于替换设备电池组。电池组的更换
需要在安全区域下进行。
Only Battery Charger type GF3.9 shall be used to recharge the batteries via
Connector ‘B’.
只允许使用GF3.9型号充电器通过B连接头给设备充电。
If the equipment is likely to come into contact with aggressive substances, e.g.
acidic liquids or gases that may attack metals, or solvents that may affect
polymeric materials, then it is the responsibility of the user to take suitable
precautions, e.g. regular checks as part of routine inspections or establishing from
the material’s data sheet that it is resistant to specific chemicals that prevent it
from being adversely affected, thus ensuring that the type of protection is not
compromised.
如果设备有可能接触到腐蚀性物质，例如酸性液体或气体，可能会对设备金属有腐蚀影响，或溶
剂可能会影响到设备的高分子材料。用户有责任采取适当的预防措施，例如把定期检查作为常规
检查的一部分，或者建立材料数据表，注明能对某些特殊化学物质有防腐功能，以防受到不利影
响。
The relative pressure range is +/-500 mbar. Note, however, that the input pressure
should not exceed +/- 500 mbar relative to atmospheric pressure and the output
pressure should not exceed +/- 100 mbar relative to atmospheric pressure.
