Manual BVS 19 ATEX E 080 X
For outdoor installation it is recommended to
protect the explosion protected distribution and
control panel against direct climatic influence,
e.g. with a protective roof. The maximum ambi-
ent temperature is 40°C, if not stipulated other-
wise.
Terminal compartment in Increased Safety
When closing, it is to be ensured that the gaskets
of the terminal compartment remain effec- tive,
thus maintaining degree of protection IP 54.
Close unused entries by impact-proof stopping
plugs, which are secured against self-loosening
and turning.
Maintenance Work
The gaskets of Ex e enclosures are to be
checked for damages and replaced, if required.
Terminals, especially in the Ex e chamber are to
be tightened. Possible changes in colour point to
increased temperature. Cable glands, stopping
plugs and flanges are to be tested for tightness
and secure fitting.
Intrinsically Safe Circuits
Erection instructions in the testing certificates of
intrinsically safe apparatus are to be observed.
The electrical safety values stipulated on the
type label must not be exceeded in the intrinsi-
cally safe circuit. When interconnecting intrinsi-
cally safe circuits it is to be tested, whether a
voltage and/or current addition occurs. The
intrinsic safety of interconnected circuits is to be
ensured. (IEC 60079-14, section 12)

对于室外安装，建议保护防爆配电和控制面板免
受直接气候影响，例如。 有保护屋顶。 最大温
度为40°c，如果没有其它规定。
端子间隔要增加安全性。
关闭时，应确保端子盒的垫圈保持有效，从而保
持IP54的保护程度。通过防冲击阻断塞子关闭
未使用引入口，这些塞子是防止自松和转动的。
维护工作
如果需要，将检查防爆增安外壳的垫圈是否损坏
和更换。 端子，特别是在防爆增安腔要拧紧。
颜色的可能变化指向温度的升高。 电缆格兰，
阻断塞子和法兰应测试紧密性和安全配件。
本安电路
应遵守本质安全设备测试证书中的安装说明。
在内部安全电路中，不得超过类型标签上规定的
电气安全值。 当互连内部安全电路时，要测试
它是否发生电压/或电流加成。 要保证互联电路
的本质安全。 (IEC 60079-14，第12款)
