Ratings, Characteristics, and Functions
*1.
An estimated value for standard mounting. Not a guaranteed value.
*2.
Conditions: With rated loads connected, at a rated input voltage, and with the battery fully charged.
*3.
Conditions: With rated loads connected, at a rated input voltage, and at the maximum battery charging current.
*4.
400 W for use as a UL compliant device.
*5.
20 A for use as a UL compliant device.
*6.
16.7 A for use as a UL compliant device.
*7.
When using in an environment at a high temperature, charging may be paused by charging temperature protection, then the charging time will
be longer than specified time.
"CS" will be displayed when charging temperature protection is operated.
*8.
For the S8BA-24D24D120LF, install all of the RSMN-2030, RSHN-2030, and RSEN-2030 EMC filters manufactured by TDK. For the S8BA-
24D24D240LF, S8BA-24D24D360LF, or S8BA-24D24D480LF, install both the RSMN-2030 and RSHN-2030 or their equivalents. Install these
filters in series to the cable connected to the DC input terminal block.
When you do, do not connect anything to the GR terminal.
The effectiveness of the noise filters may be affected by the installation environment. Be sure to check effectiveness before starting operation.
