3.1.2 Precautions before Installation
Use the power supply specified in "1.5 Electric Specification".
●
Always use the Camera under the air pressure, operating temperature and operating humidity
●
specified in "1.6 Environment Requirements".
Explosion-proof cameras are special. Power and debug them indoors, and familiarize the
●
features of them before installation.
Keep the original packing material well because you might need it to pack the Camera and send
●
it back for repair if any problem arise.
Make sure that the place where the Camera is installed has enough space to hold the Camera
●
and its mounting accessories.
Make sure that the ceiling and wall can sustain 8 times the weight of the Camera and its
●
mounting accessories.
Make sure that the wall is thick enough to install expansion bolts (Users need to buy expansion
●
bolts separately).
