While the AccuLoad is rated to operate in ambient temperatures up to 60 degrees
Celsius, it is advisable to keep all electronics as cool as possible to reduce thermal
stress on the electronic components. In hot, sunny areas, the AccuLoad should be
mounted in shade to prevent the housing from exceeding the rated temperature.
2.3. Electrical
1.
All wiring must be routed into AccuLoad through the cable entries. Do not route DC
and AC wiring through the same conduit entry.
2.
The DC signal wires must be shielded multi-conductor cable of 18 to 24 AWG
minimum stranded copper.
Note:
The following recommendations are based on our knowledge of the electrical
codes. The local electrical codes should be reviewed to ensure that these recommenda
-
tions follow the local code. Also installation manuals of all the equipment being wired into
the AccuLoad should be reviewed for transmission distances and wire recommendations.
