PQube 3 Instruction Manual
Page 18 of 103
3.1.5
Connect your PQube 3 to the power supply
Your PQube 3 can take its operating power from four different sources:
24VAC or ±24–48VDC power supply terminals on PQube 3
Power over Ethernet (PoE)
Optional PM1 Power Supply module
Rechargeable UPS module (automatically provides up to 30 minutes of battery backup
when the main power supply source drops out)
PQube 3 power supply terminals
3.1.5.1
The instrument power terminals (45 and 46) on the front of your PQube 3 must be connected to
24VAC (±20%) or 24–48VDC (±20%), supplied by a certified isolating power supply.
WARNING:
Applying voltages outside of this range can cause permanent damage to your PQube 3.
Polarity does not matter. Also, your PQube 3 provides a minimum of 150V of transformer-based
isolation between these terminals and all other terminals, eliminating any problems with ground
loops.
Power over Ethernet (PoE)
3.1.5.2
Plug in an Ethernet cable leading to a 48V PoE source (PoE switch/hub/router or PoE injector).
If no other power sources are available, your PQube 3 will request power from the PoE switch.
If your PQube 3 is already powered from another source (24V power supply or PM1 power supply
module, for example) then it will not request power from the PoE switch when you plug it in.
UPS1 Module
3.1.5.3
Plug the UPS1 module on the right side of your PQube 3 or PM1/PM2 module. This module is
always the outermost module on the right side.
By default, the UPS timer interval is 3 minutes. However, you can choose the operating duration
by writing a value in your
Setup.ini
file. The value can be set from 1 to 30 minutes. This guarantees
that there will be enough charge in the battery to record several successive power interruptions.
