EXPro Installation Manual
INTRODUCTION
THIS EXTINGUISING CONTROL PANEL IS CLASS 1 EQUIPMENT AND
This equipment must be installed and maintained by a qualified and technically competent
person.
HANDLING THE PCBS
If the PCBS are to be removed to ease fitting the enclosure and cables, care must be taken to avoid
damage by static.
The best method is to wear an earth strap, but touching any earth point (e.g. building plumbing) will
help to discharge any static. Hold PCBs by their sides, avoiding contact with any components. Always
handle PCBs by their sides and avoid touching the legs of any components. Keep the PCBs away from
damp and/or dirty areas, e.g. in a small cardboard box.
