1.  PREPARATION 

DANGER

:  Electrical shock or burn hazard. 

Installation of this DINLINE Surge Filter should 
only be made by qualified personnel.  Failure 

to lockout electrical power during installation or 
maintenance can result  in fatal electrocution or severe 
burns. Before making any connections to the electrical 
panel be sure that power has been removed from all 
associated wiring, electrical panels, and other 
electrical equipment. 

 
CAUTION NOTES

:  

 

1.  Check to make sure line voltage does not exceed 

Surge Filter voltage requirement. 

2.  Prior to installation ensure that the DSF is of the 

correct voltage, current, and frequency rating for 
your application. 

3.  The earth terminal must be connected to a low 

impedance earth (< 10 ohms) for correct 
operation. 

4.  Do not perform a “Flash Test” or use a Mega-Ohm 

Meter (Megger) to test circuits that are protected 
with DSF modules. Damage may occur to the DSF 
modules. 

5.  Follow all instructions to ensure correct and safe 

operation. 

6.  Do not attempt to open  or tamper with the DSF 

units in any way as this may compromise 
performance and will void warranty. 

 

2.  INTRODUCTION

 

Dinline  Surge  Filters  (DSF)  are  packaged  in  “DIN  43 

880”  profile  enclosures  for  simple  installation  onto 

35mm  DIN  rails.  They  can  be  selected  for  use  on 

distribution  systems  with  maximum  RMS  voltages  of 

30V,  75V,  150V  or  275V  at  frequencies  of  50/60Hz.   

For applications were the voltage regulation on site is 

poor, refer to the Transient Discriminating Filter (TDF) 

product range. 

3.  QUICK INSTALLATION OVERVIEW

 

Install in the following manner: 

1.    Ensure that power is removed from the area and 

the circuits that will be connected. 

2.    Snap lock the DSF module to the DIN rail. 

3.    Install  the  appropriate  upstream  overcurrent 

protection (refer to Section 8) 

4.    Connect wiring to the indicated input and output 

terminals. 

5.    Apply  power  and  observe  correct  operation  of 

the Status Indication LED. 

 

4.  PROTECTION CONCEPTS

 

To  optimise  effectiveness  of  the  DSF  protection,  the 

unprotected and protected  wiring should be separated. 

Wiring  from  the  exposed  transient  source  to  the  DSF 

should  be  considered  unprotected  and  kept 

approximately  300mm  from  all  other  wiring  wherever 

possible.  Wiring  on  the  equipment  side  of  the  DSF 

should be considered protected. 

The  separation  of  protected  and  unprotected  wiring  is 

recommended  to  minimize  the  risk  that  transients 

conducted on unprotected wiring may cross couple onto 

protected  circuits,  and  diminish  the  level  of  protection 

available from the DSF module. 

The  terminals  on  the  DSF  module  are  labeled 

“INPUT/LINE”  (unprotected  side)  and  “OUTPUT/LOAD” 

(protected  side)  assuming  that  the  source  of  the 

transients is on the input side of the DSF module. 

For  applications  where  the  transient  source  is  on  the 

load  side  of  the  DSF  module,  the  DSF  should  be 

reverse  connected  with  the  INPUT/LINE  terminals 

connected  to  the  load  side,  toward  the  source  of  the 

transients. 

NOTE: 

The terminals on the DSF-6A modules are 

labeled “L1”,  “L2” (unprotected side) and “E1”, “E2” 
(protected side). For DC systems the polarity of L1/E1 
connections may be either positive or negative with 
respect to L2/E2. For single phase AC systems with 
neutral it is recommended to use L1/E1 for the 
“hot”/phase/line conductors and L2/E2 terminals for 
the neutral conductors.
