WP91153 L2/L3 Replacement with L4A OK?

[pbxports]

We have a client that has asked us to replace thier WP91153 Power Supply
The system where the power supply is to be replaced has got two single carrier cabinets (SCC)
The control cabinet has the L2 version and the port cabinet has the L3 version which is the one we have to replace.

My question is can i repalce this unit with a WP91153 L4A-25 as we have one of these in stock.
As far as i can tell you can upgrade these power supplies but not downgrade so should be ok?

SCC cabinets that came with a 1217A power supply. These units have a
design flaw. They require that the breaker be reset to restore power if there is
any power fluctuation at all. Check your carrier power, if 1217A change them
out. Go to a 1217B or the older WP91153 L3.
