appropriate address switch is selected.
3.3.2 Base mounting installation
Some consideration and planning are required when locating a position to mount the base of
the receiver onto the desired surface. The base must be mounted in such a way that provides
plenty of accessible space to insert a flat-headed screwdriver, and remove the receiver cover
when maintenance and troubleshooting scenarios occur.
Because of the location of the opening mechanism on the side of the device, you will need
approximately 254 mm (10 in) of clearance on one side of the base to provide easy access to
the opening mechanism, and approximately 15 mm (0.6 in) of clearance on the opposite side
to compensate for the physical dimensions of the device cover. This should allow for adequate
space in which the device cover can be opened, and the cover removed, should the need
arise.
Other mounting considerations include;
–
Minimum clearance above the location to compensate for the vertical sliding movement
to attach or remove the device from the base is: >30 mm (1.2 in).
– Minimum clearance below the location where the base is mounted: >23 mm (0.9 in).
3.3.3 Wiring considerations
Notice!
Do not install long cable runs next to high-current power feeds. Keep cable lengths as short
as possible to minimize noise pickup.
Ensure that the wiring used meets the following specifications:
–
Four-conductor unshielded 0.65 mm (22 AWG) to 1.3 mm (16 AWG) maximum.
– Wire length must not exceed 300 m (1000 ft) from the control panel
