AccuLoad IV Installation & Maintenance Manual
Pre-Installation Considerations
14
•
A solid bracket (rear- or bottom-mount) should be used to support the AccuLoad. Refer to the
AccuLoad IV specifications (
SS06200
) for the weight and mounting dimensions.
•
The location and the height of the AccuLoad should easily permit operation of the front touch screen
and allow for a near-perpendicular viewing angle to minimize parallax effects.
•
Leave room for the front panel of the AccuLoad to open at least 90 degrees to provide access for
servicing the AccuLoad. Note that the covers are hinged on the left.
•
See the following table regarding cable access for each AccuLoad IV model. Refer to the AccuLoad IV
specifications (
SS06200
) for additional details about the location and size of the wiring access
openings in the enclosures.
2.5 Electrical Installation Considerations
Although the AccuLoad is rated to operate in ambient temperatures up to 60 °Celsius (C), 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.
In addition to this manual’s installation instructions, the following electrical warnings and precautions
should be reviewed before installation.
•
All wiring must be routed into AccuLoad through the cable entries. Do not route DC and AC wiring
through the same conduit entry.
•
The DC signal wires must be shielded multi-conductor cable of 18 to 24 American Wire Gauge (AWG)
minimum stranded copper.
•
For Ethernet connections, a minimum of Cat 5-rated cable should be used and the Ethernet wiring
practices described in the ISO/IEC 11801 should be followed for cable lengths, etc.
•
Connectors are sized for a maximum of 14-gauge wire. Consult your local electrical codes for the
minimum wire size required for your application.
•
All AC wiring should be stranded copper and must comply with federal, state, and local codes and
specifications.

The following recommendations are based on our knowledge of electrical codes. The local electrical
codes should be reviewed to ensure that these recommendations follow the local code. Additionally,
installation manuals of all the equipment being wired into the AccuLoad should be reviewed for transmission
distances and wire recommendations.
