Uninterruptible Power Supply (UPS)
The intent of the Uninterruptible Power Supply (UPS) shutdown feature on Dimension and uPrint 3D
printers is to prevent required maintenance and/or system damage by safely shutting the system
down in the event of an uncontrolled loss of power. Whether an in-process build of a part will
complete successfully is dependent on the battery life of the selected UPS and the duration of the
power outage.
The user should select a UPS with the following specifications:
•
Runtime minimum of 15 minutes at 1000W or 2000VA output (run times >15 minutes may be
appropriate based on the typical duration of power outages at the site)
•
Runtime minimum 8 minutes after low battery warning tripped.
•
Peak output (minimum) of 1500W
•
Dry contact (voltage free) interface for "On battery" and "Low battery" conditions
•
Dry contact interface capable of carrying at least 100mA at 12VDC.
General Information
Refer to the UPS and I/O Module (if used) Installation and Operation Guides for instructions on
installing the I/O module (if used) into the UPS unit as well as for connecting AC power to the UPS
and 3D printer. While connecting the 3D printer power to the UPS will provide some protection
against power outages, the 3D printer will shut down safely when "on battery" and "low battery"
conditions are detected. Follow the Electrical Interface Connection information below.
1. Configure Normally Open dry contact relay I/Os of UPS as shown in
configuration)
2. Build an appropriate length of UPS to 3D printer cable. See
3. Connect the cable from the UPS unit's connector to the UPS (9-pin DSub) connector on the rear
of the 3D printer.
Note:
their respective mates (do not over-tighten)
4. Follow the instructions in the UPS Installation and Operation Guide to set the "Low Battery
Warning Level" to 8 minutes.
Note:
time to ensure the 3D printer can shut down safely.
Make certain to install the jackscrews that hold the cable connectors to
