Location

For general location requirements refer to Figure 2. Select a
location away from strong electrical and magnetic fields. If this
is not possible, particularly in applications where mobile
communications equipment is expected to be used, screened
cables within flexible, earthed metal conduit must be used.
Install in a clean, dry, well ventilated and vibration-free location
providing easy access. Avoid rooms containing corrosive gases
or vapors, for example, chlorination equipment or chlorine gas
cylinders.
