Option 1 - Serial Communications
Serial communications provides parametric data, for example, input voltage and battery voltage.
a. Connect MultiLink serial cable included with the UPS to communications port.
b. Install the MultiLink software. The software and installation instructions, as well as the user
manual, are on the CD included in the PowerSure PSI package.
Option 2 - Contact Closure Communications
Contact Closure communications provides on-battery and low-battery signals for orderly shut-
down.
a. Refer to the MultiLink user manual for instructions on making your own contact closure
cable.
b. Install the MultiLink software. The software and installation instructions, as well as the user
manual, are on the CD included in the PowerSure PSI package.
Option 3 - USB Communications
a. Connect USB cable provided with the UPS to the PSI’s USB port and the USB port on your
computer. The PSI will work automatically with your built-in power management software on
Windows XP and 2000 and Mac OS 10.2 or later (see 8.3 - USB Interface Port for details).
Option 4 – Intellislot
The UPS contains one communication slot, called “Intellislot™,” to allow the operator to field
install optional communication cards. These optional cards allow the UPS to communicate via
either OpenComms Web Card (OCWEBCARD), connected directly to the LAN; or Intellislot Relay
Interface card (RELAYCARD-INT) communication card. Once the OCWEBCARD is installed, the
Serial communication via the RS232 is disabled. The USB, Intellislot, and Contact Closure com-
munications operate in parallel.
17. REPO Switch—The PowerSure PSI is equipped with a Remote Emergency Power Off (REPO)
switch.
The user must supply a means of interfacing with the REPO circuit to allow disconnecting the
UPS input feeder breaker to remove all sources of power to the UPS and connected equipment to
comply with national and local wiring codes and regulations.
