+15%
Output Harmonic Distortion: Less than 3% total RMS content at
full load.
Efficiency: 85% or 90% at full load typical. No loss of output for
line loss of 3 msec.

Installation

All regulators generate considerable heat and depend on the
natural draft air circulation for adequate cooling.
It is important that ventilation openings not be obstructed.
Mounting in a confined or poorly ventilated space should be
avoided unless special provisions have been made
for ventilation.

Hard-Wired Voltage Regulators

Hard-wired voltage regulators vary in size according to the
output power and may be mounted in either a horizontal or
vertical position. If mounted in a vertical position (on a wall,
for example), steel mounting hardware must be selected in
accordance with Table 1 for a secure installation. The wiring
compartment should be at the top. Regardless of position,
the regulator should be located where contact with the hot
surface of the transformer is unlikely.
For proper ventilation, allow a minimum of 12 inches of
clearance above the unit and a minimum of 6 inches of
clearance on each side. Dimensions of the regulators and
the morning brackets are presented in Figures 1, 2, 3, and 4.
The specifications for the figures are listed in Table 3.

Hard-wired regulators must be connected to a branch
circuit in accordance with local and national electrical
codes. Electrical connections are diagrammed in Figure 5.
Proper wiring is determined by the Figure indicated from the
regulator specifications in Table 3.
If operation from a 3-phase source is required, three
hard-wired regulators may be wired in delta as shown in
Figure 10.
Table 2 gives the proper jumper configurations for needed
input and output voltages. Table 2 also defines the regulator
connections in relation to the points diagrammed in Figure 6.
Fusing and wire gauge size are detailed in Table 3.
Note: Branch circuit protection must be located in the
primary of each transformer! Not in the three-phase
operation, fuses must be connected in the primary of each
unit, not in the three-phase lines.
On 7.5 and 10 kVA models, the terminal block is located in
the right unit. Use only the front or right side knockouts of
the right unit for conduit connections. On 15 kVA models,
the terminal block is located in the middle unit. Use only the
front knockouts of the middle unit for conduit connections.
Two or more models of the same rating may be connected
with their input and output in parallel. However, on models
smaller than 5 kVA, do not parallel both 208 V (X4-X5) and
240 VCT (X1-X2-X3). This may damage the
output windings.
