13. If required, attach a ground wire to the terminal lug on the rear plate.
NOTE:
The internal grounding terminal must be used for the equipment grounding connection and the external terminal is for a
supplementary bonding connection where local codes or authorities permit or require such connection.
14. Connect the video and power wiring from the sealing fittings to their sources through fittings and conduit suitable for hazardous locations.
15.
For U.S. and Canada only:
Seal the fittings as specified by the manufacturer’s installation instructions in manual C903M-C. Sealant is not
supplied or available from Pelco.
Table A.
24 VAC Wiring Distances
These are the recommended maximum distances for 24 VAC applications and are calculated with a 10 percent voltage drop. (Ten percent is
generally the maximum allowable voltage drop for AC-powered devices.)
EXAMPLE:
An enclosure that requires 80 VA and is installed 35 feet (10 m) from the transformer would require a minimum wire gauge of
20 Awg.
NOTE:
Distances are calculated in feet; values in parentheses are meters.
