DPA-150 Component identification
The DPA-150 can be fitted with up to three UPS power modules, with the uppermost module identified as module 1.
The battery fuses (F4) are identified with their associated power module on the panel silk-screen – e.g. F4-2 is the battery
fuse associated with module 2. The module parallel isolator switches (IA2) are similarly identified – e.g. IA2-2 pertains to
power module 2.
Note that the module input mains fuses (F1) are located within the modules and are not accessible with the module in-situ.
