Physical Installation
Check for ideal indoor location
Stay away from electrical or communication devices
The
The cabinet should be mounted indoors, in a secure location providing normal temperature and humidity, leaving 23 cm (8 in) clear space around all sides and a minimum of 33 cm (13 in) clear space in front of the cabinet. The location should be easily accessible for servicing the equipment and it is recommended that controllers be located close to the controlled doors.
Controllers must be located at a minimum distance of 2 m (6 ft) from any high voltage equipment or wiring and from electrical equipment susceptible of generating electrical interference, at a minimum distance of 1 m (3 ft) from telephone equipment or lines, and at a minimum of 8 m (25 ft) from any transmitting equipment. Physical access, using keys, on controlled doors must be provided so that the
Earth Grounding
AWG #18 grounding wire to EGND
Since the
An AWG #18 single conductor copper wire must be used to ground each controller to good earth ground as per the local electrical code (be careful with ground loops). The ground clamp should be located below any other ground.
Door Locking Devices
