S
As a remote on/off (ROO) contact that allows the UPS to be turned on
and off from a customer-supplied switch in a remote location.
If the ROO function is installed, turning the UPS on and off from the
front panel is NOT available. If the UPS is in manual Bypass mode,
turning the UPS on through the front panel transfers the UPS to
Normal mode.
Two REPO/ROO positions may be used: normally-open or
normally-closed. The pins on the normally-open REPO connector are not
connected together. When this connection is closed:
S
For REPO, the logic circuitry completely shuts down the UPS, thus
preventing the power from supplying the load.
S
For ROO, a remote on signal energizes the load, and opening the
connection sends a remote off signal that de-energizes the load.
NOTE To restart the UPS, reconnect the REPO connector pins and turn on the UPS
manually. The pins must be shorted (maximum resistance 1000 ohms) to keep the UPS
running.
NOTE Disconnect the load when changing the active state of the ROO contact. The load
will energize or de-energize as soon as the state is changed, depending on whether there is a
jumper installed.
S
The REPO must not be connected to any utility connected circuits. Reinforced insulation
to the utility is required. The REPO switch must have a minimum rating of 24 Vdc and
20 mA.
S
To ensure the UPS stops supplying power to the load during any mode of operation, the
input power must be disconnected from the UPS when the emergency power-off function
is activated.
S
When REPO is activated for a UPS with line-to-line 208V input, the output receptacles
will have 120V neutral (L2) to ground.
