Sentinel 150P installation, operation & maintenance 

ci0050   p6/8   issue 5   2014-08-26 

 

AC Input (power supply) 

DANGER !

HIGH VOLTS

 

Before AC connection, disconnection or 
fuse replacement: 

  Isolate the AC supply 

  Ensure a good ground/earth connection 

to the charger (CN3 screw terminal). 

  Ensure the AC supply voltage is 

compatible with the charger’s supply 
rating.

 Exceeding the rated voltage 

may result in damage to the charger 
and connected equipment, and cause 
serious personal injury.

 

  Fit external supply fuses in accordance 

with the charger's labelled types/ratings. 

 

WARNING:

 Sentinel should be fused 

separately from other equipment.  
This will prevent Sentinel being isolated, 
and ensure batteries remain on charge, 
in the event that other equipment fails.  

Connect the AC input supply (live, neutral and ground) 
wires to Sentinel connector CN3:

 

CN3 

pin 

Function 



AC supply live, 95 to 265 VAC, 47 to 63 Hz 
AC supply neutral 
AC supply ground/earth 

AC supply and ground connections require 1mm²/17 
AWG or larger wire conductors, rated for temperature 
90°C/194°F. The AC live wiring must incorporate fuse 
ratings/types as indicated on the charger labelling.  

Sentinel 

– PC connection 

SNTL150P-PCCON configuration software kit 

To allow the full range of programmable functions and 
options, Sentinel must be connected to a Windows®-
based PC or laptop running Computronic SNTL150P-
PCSUITE software. 

Configuration kit model SNTL150P-PCCON provides all 
the necessary hardware for communication between PC 
and Sentinel 150P charger.  

The kit includes a communication lead with a 7-way pin 
header, which connects to the Sentinel 150P circuit 
board. Sentinel back view: 

 

 

7 way pin header H1 

Connection: 

 

Ensure correct polarity when mating with USB to  
Serial TTL converter cable (as supplied with 42.70.3825):

Notes: 
1) External AC fusing (F1):  

see AC Input (power supply) section 

2) DC self-resetting fuse (F2):  

see DC Output section 

3) Battery output is isolated from chassis. 
4) Alarm output relay shown in de-energised 

state. Output function is configurable. 

5) Input (pin 7) shown with momentary 

action switch. Input function is software 
configurable.
