AccuLoad IV Installation & Maintenance Manual
Installation 16
3 Installation
The general steps in the installation process are to physically mount the AccuLoad, electronically connect it
to work with associated equipment, and then configure it to suit its specific operational and measurement
environment. This manual provides information about the electrical installation of the AccuLoad IV.
For dimensional drawings and basic requirements for mounting the AccuLoad IV, see the AccuLoad IV
specifications (SS06200). For information about configuring the AccuLoad IV, refer to the AccuLoad IV
Operator Reference Manual (MN06200).
3.1 General Electrical Installation Requirements
It is imperative that the electrical installation be performed by a qualified individual who is familiar with
associated risks involved with the installation, operation, and maintenance of electrical equipment in
hazardous (classified) locations. This individual must possess knowledge of local and national electrical
codes, in addition to ordinances concerned with hazardous location safety requirements. It is
recommended (may be required in some jurisdictions) that the final installation be verified and inspected
by the authority having jurisdiction before placing the equipment into service.
Electrical installations in hazardous areas have features specifically designed to make them suitable for
use in such locations and it is the operator’s responsibility to maintain the integrity of those special
features.
The operator must ensure that electrical equipment is:
• Installed and operated correctly
• Monitored on a regular basis
• Maintained with due regard to safety
Additionally, the following guidelines should be followed:
• AC Circuits must be isolated from DC circuits and brought into the unit through their respective
conduit openings.
• Be sure all connections on the terminal blocks are tight.
• All shields must be connected to terminals 3, 13, 14, or 15 on terminal block TBE4 on the A4M Board or
terminals 9 and 10 on TB14 on the A4B Board.
• All exposed shields must be properly insulated to prevent short circuits to other terminals or to the
chassis. The shield at the device (such as a temperature device or transmitter) must be cut back to the
insulation and taped off. All shields should be continuous. If splices are required, they must be soldered
and properly insulated. If other communicating devices are used with the AccuLoad, refer to the
manual for that unit for shielding information. Shields for other communicating equipment should not
be terminated in the AccuLoad.
Shields must not be terminated at the ground lugs.
