FUNCTIONAL DESCRIPTION
The DSFi is designed to provide protection against
power surges caused by external sources such as
lightning strikes and electrical switching. The unit is
designed in accordance with AS3100, AS1768,
IEC61643-1, IEC61000-6 ANSI/IEEE C62.41 and
other standards and codes as applicable.
The DSFi is a 3-stage protection unit utilising primary
and secondary MOV protection in conjunction with a
2-stage L/C filter using separate differential and
common-mode circuits. The differential filter provides
filtering of surges, line harmonics and high-frequency
noise with a cut-off frequency below 1.5kHz, and an
attenuation of >60dB at 1MHz and >55dB to 10MHz.
The common-mode filter provides >55dB to 10MHz.
OPERATION
Two lamps on the front panel indicate the operation
status of the unit. The ‘OK’ lamp indicates that power
is applied to the unit and the ‘FAULT’ lamp indicates
reduced protection. If the ‘FAULT’ lamp is lit it is likely
that the unit is damaged and must be replaced. If the
breaker/fuse is intact and power is definitely being
supplied through the unit (check with meter) but the
‘OK’ lamp doesn’t light then the unit is faulty and
must be replaced.
WARRANTY
Eaton Power Quality warrants this unit against faulty
parts and workmanship for a period of 12 months
from the date of purchase. If this product fails to
operate correctly, please contact your Eaton
representative. This warranty doesn’t cover neglect
or intentional misuse. As this product is intended for
use in electrically harsh environments no claim is
made of suitability for purpose. This unit is designed
to reduce the likelihood of damage, not prevent it.
Please also note that an excessive surge, such as
from a direct lightning strike to the site or a power
system fault, may cause damage to the unit and
render it inoperable. A unit that has been damaged in
this way is not warrantable.

INSTALLATION
Refer to the procedure and diagram shown to connect the DSFi.
PROCEDURE:
1. CHECK
! Always work safely – disconnect power before making
connections.
! All wiring must be carried out by suitably qualified
personnel according to the applicable standards.
! Check for correct operating voltage and power system.
This model (DSFi) is designed for TN-C and TN C-S power
systems in the range of 200-250V. If your power system is
different or a different voltage, this model is not suitable.
Please contact your supplier for information.
! Always use the correct size supply fuses or breaker(32A
max.).
2. INSTALL
! Remove 4 screws on face of unit and remove
termination covers.
! Fit cable glands as required. If glands are not required,
use a grommet to prevent cable damage.
! Install unit to switchboard geartray, equipment cabinet or
other suitable location. Do not expose to direct sun or
water. Allow plenty of ventilation - do not mount inside a
small or sealed enclosure.
3. CONNECT
! Connect wiring - refer to connection diagram.
! Use a suitably rated cable for power connections and
6mm2to 10mm2cable for earth connections.
! Tighten glands if fitted. If not using glands, use cable ties
to secure cables.
! Use short cables for phase, neutral and earth input
connections or protection will be reduced.
! Use a suitably-rated cable for alarm connections. Cable
should be rated for operation at the system voltage and
should be 0.5mm2to 1.5mm2.
! Refit termination covers and screws.
4. NOTES:
! Wiring to the unit’s input is carrying surge currents as
well as load current. Use the shortest possible
connection lengths. Keep input and output cables apart
! Maximum alarm relay resistive load is 5A.
! It is recommended not to connect the alarm contacts to
AC mains circuits if possible, to prevent flashover from
surges on the AC line. Connect to a PLC or BMS if
available.
! Do not Megger test cabling with unit connected.
EARTHING
For proper operation, all surge filters rely upon a good earth
connection. In some installations the existing earth system may
require upgrading. Important things to look for are:
! The main earth wire (from earth link on switchboard to ground
rod or system) MUST be at least 6mm diameter (preferably
larger) and should be as short as possible.
! Earth connections from the unit to earth link MUST be as short
as possible.
Failure to consider the above points can result in improper
operation of the unit and possible damage to the installation.
Normal connection
Series-load connection
- Install separate equipment earth if practical.
