item «Pdd» and set «ON» status. If «OFF» status is selected, the function is switched
off.
SB deep discharge protection may be used only if load switched connection is
used, see Figure 5.
If direct connection is used, see Figure 4, protection function shall be switched
off.
SB deep discharge protection activates at residual voltage 19.2 V – for SB 24 V
and 9.6 V – for SB 12 V.

Energy saving mode
Energy saving mode enables to prolong time of load powering from SB. Digital
LCDs (to display present values of charge current and voltage) are switched off in this
mode.
Energy saving mode is activated automatically in case of power mains failure.
To activate LCDs, press «SELECT» button on the casing; they will start dis-
playing within 3 sec.
In case of main power recovery energy saving mode is switched off.
2.3.9
Recommendations on charge current values
To recharge SB, set the current values in compliance with the Manufacturer’s
recommendations (factory parameters) given in SB certificate.
If, for any reason, it is impossible, the Manufacturer recommends to set charge
current values not more than 10 % from SB capacity.
Sample calculation:
At SB capacity (С) – 150 А·h, charge current equals С
150
* 0.1 = 15 А.
Note – This current value prevents SB from damage in case of overcurrent.
2.3.10
Recommendations on charge voltage values
SB charge voltage shall be set in compliance with SB documentation (factory
charge voltage parameters).
If, for any reason, it is impossible, the Manufacturer recommends to set charge
voltage values 28.4 V for SB with voltage 24.0 V, and 14.2 V for SB with volt-
