Nut upsdev - Oct 2009 - Shutdown N-POWER MV-1000 LT UPS is not working

Hello! 
I use online UPS MV-1000 LT 
http://www.230v.ru/catalogue/?id=production/ups-sm/master-vision 
for the power of my Linux server SLES 10 SP1. 
I downloaded, compiled and configured diver nut 2.4.1 from this link 
http://www.networkupstools.org/source/2.4/nut-2.4.1.tar.gz 
Here are my configuration files:

Everything works. 
But I can not turn off the UPS after stopping the server operating
system.
How 'upsdrvctl shutdown' or 'megatec-a npower-k' or
'upscmd-u admin-p
karamba npower shutdown.stayoff' does not bring results. 
I joined up with the UPS through a terminal program "minicom" and send
commands to the description of the protocol megatec ->
http://www.networkupstools.org/protocols/megatec.html
Instruction S01 successfully stops the UPS, if there is no input
voltage. 
This protocol confirms this

Please'll show what I configured wrong? 
Thanks in advance.

Add
     offdelay = 1
     ondelay = 3

to the ups.conf file. Unfortunately, the default value of '0' is not  
accepted by older UPS implementations of the megatec protocol. Make  
sure to wait at least one minute after issuing this command. See also  
'man 8 megatec'.

You could also try the 'blazer_ser' driver, which uses more  
conservative defaults here. See 'man 8 blazer' for more information on  
this driver.

Best regards, Arjen
