1.0 Important Safety Instructions

Please read all safety, installation, and operating instructions before attempting to install or operate the unit.

!

DANGER

High voltages are present inside the unit. Do not reach inside while it is energized. This unit contains no user­serviceable parts.

2.0 Warnings Defined

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.

3.0 Introduction

The SolaHD Micro/Mini Computer Regulator (MCR) 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.

4.0 Installation Instructions

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 and Important Factors to Consider

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.

When utilizing MCR units, please consider these important factors:

• Motor or Inductive Loads: The MCR and CVS products have a fast response time and a built-in overload

protection which causes the output voltage to collapse during an overload condition. Due to this
protection function, the load must not draw more than the unit's rated capacity, even momentarily. For
this reason, care needs to be considered with highly inductive loads (e.g., motors, pumps, contactors,
solenoids, air conditioners, etc.).

You may size the conditioner based on the peak current rating, but you will need to meet the Minimum
Load requirement. This is the reason why SolaHD highly recommends only using these CVS and
MCR products for resistive or electronic loads.

• Minimum Load: Minimum loading of no less than 40% of the nominal rating because output voltage will

rise by 1% as the load is decreased. Units with less than 40% load may run hotter than those at close to full
load. This may result in overheating in the long run.

• Frequency: The output voltage varies linearly with changes in Input Frequency. A 1% change in input

frequency will yield a 1.5% change in output voltage. 60Hz models cannot be used with 50Hz application
and vice versa. This is also the reason why we don't recommend these units with generator source that has
varying input frequency.

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 conned 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.
