Mount DTMs within the length of the provided cable from the 5009 main unit,
leaving adequate service loop.
For each DTM:
1. Mark DTM mounting hole locations, taking care to leave sufficient space
between the DTM and walls, objects, etc. for easy access. The master DTMs
(1, 3) must be mounted directly above the slave DTMs (2, 4); within a
maximum distance.
2. Drill and tap mounting holes.
3. Place the DTM in position, insert mounting screws into the tapped holes, and
tighten them securely.
4. If the panel the DTMs are mounted on is not at earth ground potential
connect it to earth ground via a 12 AWG (4.0 mm²) or larger green/yellow
wire or braid; keeping the wire/braid as short as possible.
