2.4.8.3.4. Relay Outputs
The relay outputs can switch up to 250 VAC or 30 VDC voltages at 1A maximum. The relay outputs
are not polarity-sensitive since they are dry contact outputs. An example of wiring to the outputs is
given in Figure 2-44.
2.5. Capacity Label Instructions
The regulations in some locations require that the scale capacity and increment be shown on the
front of the terminal, near the display. To satisfy this requirement, a blue capacity label is included
with the terminal that must be completed and adhered to the overlay.
The capacity label (shown in Figure 2-45) provides space for the Max, min, and e information for
each range for which the scale is programmed. The unused portion of the label may be cut off with
scissors. Written information must be legible and a minimum of 2mm or 0.08 in. in height. A
permanent marker should be used.
Clean any oil or other contaminants from the area where the capacity label will be added. Peel the
backing from the label and adhere it to the overlay or in another location acceptable to the local
regulations.
