1.0 Important Safety Instructions

3.0 Introduction
4.0 Installation Instructions
!
DANGER! High voltages are present inside the unit. Do not reach inside while it is energized. This unit contains no
user-serviceable parts.
DANGER! Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. This signal
word is limited to the most extreme situations.
WARNING! Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.
CAUTION! Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury. It may also
be used to alert against unsafe practices.
The SolaHD Constant Voltage Sinusoidal (CVS) transformer provides voltage regulation and isolation from both transverse and
common mode noise for any type of load. It also suppresses transients with ferroresonant, protects overloads, and serves as a
dedicated line. It is the ultimate in ac power conditioning equipment.
4.1 Receiving
Upon receipt, immediately inspect the unit for obvious signs of shipping damage and/or mishandling. If damaged, photograph the
unit, inform the carrier, and contact your SolaHD representative.
4.2 Mounting & Ventilation
These units are for use in an indoor humidity and temperature controlled environment. Mount the unit in either a horizontal or vertical
position. The unit should be located where contact with the transformer’s hot surface is unlikely. If mounted in a vertical position (e.g.
on a wall), steel mounting hardware must be selected in accordance with Table 1. The wiring compartment should also be facing up.
Table 1: Mounting Hardware
CVS Rated VA Steel Mounting Screws (Minimum Diameter)
30–120 VA #10 machine screws
250 VA 1/4 in. bolts

15000 VA 1/2 in. bolts
All regulators generate a considerable amount of heat and depend on natural convection for adequate cooling. It is important
that ventilation openings not be obstructed. Mounting in a conned or poorly ventilated space should be avoided, unless special
provisions have been made for ventilation. For proper ventilation, allow a minimum of 12 inches of clearance above the unit and
minimum of 6 inches of clearance on each side.

5.0 Parallel & Three-Phase Connections
5.1 Parallel Operation
!
In Grounded WYE
Units of the same SolaHD catalog number may be connected in parallel to obtain a larger load capacity. Both input and output
connections must be made in parallel (see Figure 6). The SolaHD catalog number must end in -8 or -C8 and must be larger than 1
kVA. No portable units can be paralleled.
All input and output paralleling wires must be tied together in an external paralleling “box” provided by the user. Do not attempt to
jumper the wires of one unit to the terminal block of the other unit. The terminal block may not be rated to carry the total currents
of both units. The input of each unit must be properly and separately fused.
CAUTION! Failure to adhere to these requirements may damage the windings.
For units smaller than 5 kVA: When connecting in parallel the 208 Volt windings, other output voltage ratings (120 V, 240 V) can’t
be paralleled at the same time and vice versa. It is suggested that the installer remove X2 grounding on each unit, then connect
X2 from each unit to one location and ground at that location only.
5.2 Three-Phase Connection Operation
Loads requiring 4-wire WYE connection may be served by three ferroresonant power conditioners with the same SolaHD catalog
number. The inputs must be connected in Delta. Input fuses must be connected in the primary of each unit, not in the three-phase
lines. The outputs must be connected in WYE with the neutral solidly connected to a WYE load. Alternatively, these three outputs
may serve three independent single-phase loads. Phase angles may vary somewhat from 120 degrees even with balanced
loading.
This circuit arrangement is not intended to serve single-phase line-to-line loading or three-phase Delta loading. Outputs must
serve three independent, single-phase loads of the same total Volt-Amphere (VA) rating. Connections should be made in one of
two ways as shown in Figure 6.
The outputs of the unit are isolated from the input lines. Voltage generated by internal leakage currents will occur with respect
to ground, which can have undesirable effects in electronic equipment. Therefore, if circuit “B” is used, it is suggested that the
installer remove X2 grounding on -8 units, then connect all X2 from each phase to one location and ground at that location only.
This is not required for circuit “A” and will not affect regulation or the ability to reject power line noise or transients.
