OPERATION AND MAINTENANCE
The units have been designed to comply with relevant spark ignition tests.
Warning:
To maintain a safe condition, do not use an external keyboard or mouse
when the unit is operating in a hazardous environment.
Always observe the following rules with respect to hazardous location installations:
1.
Always install the workstations within an enclosure suitable for the specific appli-
cation. General purpose enclosures may be acceptable for Class I applications, but
are never acceptable for Class II applications. Type 4 (IP 65) enclosures are recom-
mended even when not required by regulations.
2.
Keep enclosure doors or openings closed at all times to avoid the accumulation of
foreign matter inside the workstation.
3.
Never subject the unit to any installation or service procedures unless power is re-
moved and the area is non-hazardous. This includes installing or removing power
cables or communication cables, or removing the unit’s back cover.
4.
Only technically qualified service personnel should perform installation and ser-
vice. These workstations are designed to require no service in the course of nor-
mal operation by an operator.
