To install the DC input / output wiring to the UPS:
1.
Use the recommended user-supplied wiring to connect the DC UPS Input and Output terminals.
2.
Use the recommended user-supplied EBM wiring from Table 1 to connect to the DC UPS battery (BAT + /
-) terminals.
3.
Connect other end of BAT wiring from the DC UPS to the closet set of +/-terminals of the EBM.
4.
Add additional BPDIN24XL extended battery modules by following the above steps. Ensure each of the
EBMs are at a minimum distance of 0.39 in. (10 mm) between each module. Up to four EBM modules can
be used per UPS.
5.
Turn on Mains DC power and check with a voltmeter to verify 24V DC is present across all positive and
negative terminals. Power the UPS ON by pressing the button for 3 seconds. As long as live 24V DC is
supplied to input terminals the output terminals will be live in bypass and Line operation modes.
6.
For connection to remote ON/OFF, dry contacts and support information, refer to the Advanced User’s
Guide at Eaton.com.
