9. Connect 2-wire 90-277 VAC power to main power terminals. Observe polarity. For
the ASPMETERA and ASPMETERB, connect voltage lines to the voltage taps (Figure
8). Equip voltage lines with fuses.

7. Wire RS-485 communications (see diagrams in Wiring section, page 6).
8. Connect 0.333 VAC CTs to the main conductors by snapping CTs around lines,
observing local codes regarding bending radius (optional; Figure 6).

Recommended CT:
Veris Industries H6810, H6811, H6812 Series with 0.333VAC output.
Available in 100A max. to 2400A max.
Call a Veris sales rep if higher amperages are required.
SAFETY
If ASPMETER products are used in installations with circuits higher than the product
ratings, the circuits must be kept segregated per UL508A Sec. 17.5.
Note: 277/480 VAC Wye connected (center grounded) power systems operate
within the 300 VAC line to neutral safety rating of the ASPMETER series, and
the operational voltage limit (single-phase connection) as the line to neutral
voltage is 277 VAC in such power systems. Corner-grounded delta 480 VAC
systems would not qualify, as the actual line to earth voltage is 480 VAC on
each leg, exceeding the ASPMETER ratings.
Note: ASPMETER internal circuitry (cables and CTs) are not circuits as defined
by UL508A, as they do not extend beyond the ASPMETER itself without
further safety/fire isolation.
UL listed under standard 508 as an “open type device.”
Maximum ambient air temperature for use is 60°C.
Installation category: CAT III
The ASPMETER Series must be installed in an appropriate electrical and fire enclosure
per local regulations.
For use in a Pollution Degree 2 or better environment only.
A Pollution Degree 2 environment must control conductive pollution and the
possibility of condensation or high humidity. Consideration must be given to the
enclosure, the correct use of ventilation, thermal properties of the equipment and the
relationship with the environment.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the device may be impaired.
IEC/EN 61010-1
This symbol indicates an electrical shock hazard exists.
Documentation must be consulted where this symbol is used on the
product.
