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.

Output Voltage and Frequency: 110/120/220/240 VAC

Output Voltage Regulation: +3% for an input line variation of

+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.

Noise Reduction: Common mode noise rejection exceeds 120dB.

Transverse noise rejection exceeds 60dB.
