2.4 Measures

Distributed I/O device 6DL2804-xxxxx

8Hardware Installation Manual, 03/2014, A5E00378896F-03

2.4

Measures

In the interest of safety, observe the following precautionary measures:

WARNING

Type of protection "Flameproof enclosure d"

Devices with "pressure-resistant encapsulation" protection may only be opened when the

power has been disconnected.

Type of protection "Intrinsic safety i"

"Intrinsically-safe" devices lose their certification as soon as they are operated on circuits

which do not correspond with the test certification valid in your country.

Type of protection "Increased safety e"

Devices with the type of protection "Increased safety" must not produce sparks or electric

arcs during operation under normal conditions. Electrical equipment and parts must not

exceed a rated voltage of 11 kV.

Type of protection "Mold encapsulation m"

Devices with the type of protection "Mold encapsulation" are potted in casting compound.

Type of protection "By means of enclosure t"

Devices with the type of protection "By means of enclosure" prevent the penetration of dust

or reduce it to a harmless level. Explosive equipment can be installed. The temperature on

the housing must not ignite the surrounding atmosphere.

WARNING

Use in environments with aggressive and dangerous media

The device can be operated both at high pressure and with aggressive and hazardous

media. Therefore, improper use of this device may lead to serious injury and or

considerable damage to property. Above all, it must be noted when the device was in use

and is to be exchanged.

CAUTION

Electrostatic sensitive devices

This device contains electrostatic sensitive devices. ESD devices can be destroyed by

voltages well below the threshold of human perception. These static voltages develop when

you touch a component or electrical connection of a device without having discharged the

static charges present on your body. The damage to a module as a result of overvoltage

cannot usually be detected immediately. It may only become apparent after a long period of

operation.
