HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH |
|
oDisconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires except under the specific conditions specified in the appropriate hardware guide for this equipment. oAlways use a properly rated voltage sensing device to confirm the power is off where and when indicated. oReplace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit. oUse only the specified voltage when operating this equipment and any associated products. |
|
Failure to follow these instructions will result in death or serious injury. |
|
|
|
POTENTIAL FOR EXPLOSION |
|
oUse devices with explosion protection as intended according to these operation instructions and corresponding documents. oConform to valid safety and accident prevention regulations and adhere to standards such as IEC/EN 60079-14. oBe sure that all other associated equipment, such as cables and connectors, are also suitable for the operating location. oGround all devices, using a metal plate, terminal strip or mounting plate securely connected to the housing back plate, to an equalized potential. oDisconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires except under the specific conditions specified in the appropriate hardware guide for this equipment. oDevices must remain voltage free until all installation or maintenance work is completed. oRemove as necessary dust collecting on devices that can cause explosions. oBe sure that all connectors and sealing plugs on the M8 and M12 connectors are in place and fastened with a torque between 0.2 and 0.4 Nm (1.8 and 3.5 lbf-in) before applying any power. oBe sure that all connectors are firmly sealed with either properly wired connectors or sealing plugs before applying power during regular operation. |
|
Failure to follow these instructions will result in death or serious injury. |
|
|
|
POTENTIAL FOR EXPLOSION |
|
oOnly use this equipment in non-hazardous locations or in locations that comply either with the Class I, Division 2, Groups A, B, C and D, or with the ATEX Group II, Zone 2 specifications for hazardous locations, depending on your local and/or national regulations. oDo not substitute components which would impair compliance to the hazardous location specifications of this equipment. oDo not connect or disconnect equipment unless power has been removed or the location is known to be non-hazardous. |
|
Failure to follow these instructions will result in death or serious injury. |
NOTE: Additional equipment used in conjunction with the equipment described herein must also be suitable for the operating location.
|
|
|
LOSS OF CONTROL |
|
oThe designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart. oSeparate or redundant control paths must be provided for critical control functions. oSystem control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link. oObserve all accident prevention regulations and local safety guidelines.1 oEach implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |

|
UNINTENDED EQUIPMENT OPERATION |
|
oOnly use software approved by Schneider Electric for use with this equipment. oUpdate your application program every time you change the physical hardware configuration. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
