2.2.9 Installing a PM1 or PM2 Power Supply Module
The optional PM1 or PM2 Power Supply Module connects to the right side of your PQube 3; just plug
it in. It accepts any 50/60/400 Hz single-phase input between 100 Vac and 240 Vac nominal. Verify
that you are connecting the line and neutral wires to the correct terminals on the module.
2.2.10 Installing UPS Module
The UPS1 Module provides backup power to your PQube 3 in the event of complete loss of
instrument power. Plug it into the right side of your PQube 3. If using a PM1 Power Supply Module,
plug the UPS module into the right side of the PM1/PM2 module. The lithium-ion battery pack can
provide power between 3 and 30 minutes (user-configurable).
If more power duration is required UPS2 or UPS3 with optional battery packs can be used.
