Without doubt, power interruptions cause major problems for home and business
computing. An unpredictable power supply can lead to worrying problems such as
surges, spikes, lightning strikes, brown-outs, power-cuts (black-outs), power-back
surges, mains over-voltage, and complete failure - all of which can damage electrical
and electronic equipment. If any of these should occur, there’s a strong chance you
will suffer
from loss of critical data, lowered productivity and even damage to your
expensive equipment.
Sollatek encompasses a wide range of power protection products for use in many
different industries where clean, regulated mains power is critical to their continued
operation.

INTRODUCTION
This document explains how to install the Sollatek DSP-D Series of AC Panel Surge
Protective Devices.
INSTALLATION INSTRUCTIONS
The suppressor should be mounted on or near the panel as close as possible to the
wire connection point. The suppressor has three mounting possibilities: surface, fl ush
or close nipple. In all three mounting possibilities connect the BLACK #12 AWG solid
wires to the phase conductors, connect the WHITE #12 AWG solid wire to the neutral
bus and connect the GREEN #12 AWG solid wire to the ground bus. At the installation
stage, cut each conductor AS SHORT AS POSSIBLE. Avoid large loops of wire and
sharp bends in the wires. Bind all connecting cables tightly together throughout the
wire run from the Sollatek DSP-D to the panel.
MOUNTING
Close Nipple Mounting:
Choose a location on the panel that will give the most direct connection to the phase
conductors and neutral-ground busses. Use a pre-existing ½ inch conduit knock-
out or drill a new ½ inch conduit hole in the panel. Remove the conduit nut from the
Sollatek DSP-D and slide the wires and conduit nipple into the panel. Reconnect the
conduit nut to the Sollatek DSP-D.
CAUTION: the conduit connection is plastic, DO NOT OVER-TIGHTEN. Connect wires
as described above.
Surface Mounting:
Choose a location near the panel that will give the most direct connection to the phase
conductors and neutral-ground busses. Use a pre-existing ½” conduit knock-out or
drill a new ½” conduit hole in the panel. Remove the conduit nut from the Sollatek DSP-
D Series and slide the wires and conduit nipple into the panel. A short piece (less than
3”) of plastic conduit may have to be added to the Sollatek DSP-D. Connect either the
close nipple on the Sollatek DSP-D or the short additional piece of conduit to the panel.
Use the four 0.20” mounting holes on the Sollatek DSP-D Series and secure it to the
wall using appropriate hardware (not supplied). Connect wires as described above.
Flush Mounting:
The fl ush mount Sollatek DSP-D Series is installed into a suitably sized hole in the wall.
This hole needs to be large enough for the body of the suppressor, yet not exceed the
fl ush mount plate mounting holes. Choose a location near the panel that will give the
most direct connection to the phase conductors and neutral-ground busses. Use a
pre-existing ½” conduit knock-out or drill a new ½” conduit hole in the panel. Remove
the conduit nut from the Sollatek DSP-D Series and slide the wires and conduit nipple
into the panel. A short piece (less than 3”) of plastic conduit may have to be added
to the Sollatek DSP-D Series. Connect either the close nipple on the Sollatek DSP-D
Series or the short additional piece of conduit to the panel. Use the four mounting holes
on the Sollatek DSP-D Series fl ush plate and secure it to the wall using appropriate
hardware (not supplied). Connect wires as described above.
INCORRECT INSTALLATION WILL IMPAIR THE EFFECTIVENESS OF AC PANEL SURGE
PROTECTORS. Particularly important is the length and routing of the connecting
leads.
STATUS INDICATOR
NOTE: ALL WIRES MUST BE CONNECTED AND POWER APPLIED BEFORE THE LED
WILL ILLUMINATE.
The Sollatek DSP-D Series of suppressors has comprehensive, solid state, continuous
visual status monitoring present in each unit. The GREEN indicator light will go out
in the event the suppressor capability is exceeded or if there is an internal safety
component failure. If the light goes out, call the factory for replacement instructions.
Panel LED Mount Models only:
Specifi c Sollatek DSP-D Series models have the
capability of panel indication. Drill a 0.280” hole in the panel in the desired location.
Maximum panel thickness is 0.125”. Remove the lens from the LED holder and snap
it into the panel. While holding the lens in place, snap the LED holder onto the lens.
Use the supplied wire nut to connect the wires, matching the color codes on the
suppressor to those on the LED holder.
REMOTE STATUS INDICATION
Each Sollatek DSP-D Series has remote indication of the protector status. This is
available as a normally closed dry contact. To utilize this feature, connections are
made to the pair of stranded RED #18AWG wires. If this loop opens, it indicates a
failure of the Sollatek DSP-D Series. Call the factory for replacement instructions. If
remote indication is not used, RED wires can be cut and taped off.
MAINTENANCE
At intervals not exceeding two months, check:
1. Status indication lights
2. Conditions of connecting cables and terminals

POWER PROBLEMS AND THEIR ASSOCIATED CAUSES
All electrical and electronic equipment, connected to the mains supply is at
risk of being damaged from spikes, surges, lightning, brown-outs, power-
cuts (blackouts), power back surges, and over-voltage.
The following is a summary of the main types of power problems, causes
and how these affect electrical and electronic equipment.
Spikes/Surge:
Very short, (one millisecond) event of very high surge in voltage to thousands of volts and amps. Spikes are common in all parts of the world and
repeated exposure to spikes will damage electronic equipment and corrupt data.
What causes it?
Switching on/off of nearby equipment, lightning, motors starting etc.
RFI (Radio Frequency Interference)/Noise:
High frequency disturbances that occur within a short period of time (milliseconds). RFI & noise are very common in
all parts of the world and are the main cause of data corruption.
What causes it?
Generated by high frequency noise from nearby equipment like TV, radio equipment, transmitters, mobile phones, switching on/off of certain
loads, fluorescent lights, motor speed controls, light dimmers.
Over-Voltage:
Long duration (milliseconds, seconds, minutes, hours or days) rise in the voltage above acceptable limits. Depending on the level of the over-
voltage, the damage can be instantaneous, severe and irreparable.
What causes it?
On return of mains supply after power cuts, under-sized utility oscillating between periods of brown-outs and over-voltage or accidental (e.g.
accidental connection between two phases).
Brown-Out:
Long duration of low voltage (milliseconds to seconds, minutes, hours or days). Very common in parts of the world especially where the power
utilities are over-stretched. Prolonged and frequent brownouts cause the equipment to malfunction or not work at all. Repeated episodes are certain to cause
damage. Motors and compressors (and therefore fridges, freezers, coolers, air-conditioners and pumps) are especially at risk. In time, damage is certain.
What causes it?
Most commonly an over-stretched utility, especially in areas of poor power distribution infra-structure and remote areas. Common in dry
seasons where water is used for electricity generation.
Lightning:
Direct or nearby strikes can cause minor problems or severe disturbances and damage. Lightning produces spikes/surges, over-voltage or power
cuts.
What causes it?
The surge is generated by either a direct hit, or indirectly striking underground or overhead lines and transmitting high surges to connected
equipment in nearby buildings.
Power-cuts:
Common in many countries in the world, especially in areas of frequent voltage problems. Sudden loss of power can cause damage ranging from
corruption of data to mechanical faults as equipment is stopped while in operation.
What causes it?
Power or sub station failure, breakdown in the distribution network, or simply a plug being pulled out accidentally.
Power-Back Surges:
These typically occur when power returns after a power-cut and connected equipment receives a surge of electricity at an over-voltage
level, which can be very damaging (see above).
What causes it?
Power back surges are created by the utility, when it restores supply at an above normal voltage in order to compensate for the demand as
connected equipment re-starts simultaneously.
Telecom surges, spikes and lightning:
Short term, high voltage and current phenomena occurring on the telephone lines. Can cause irreparable damage to any
piece of equipment connected to the incoming line. The telephone line itself may even be damaged or destroyed in severe cases.
What causes it?
Telecom spikes are caused by lightning striking either the telephone line directly or an object near it.
