WARNING! Risk of electrical shock. Can cause equipment damage, injury and death. The EPO
action of the UPS will shut down the rectifier, inverter and static bypass, but it does not
disconnect input power to the UPS. To electrically isolate the UPS, an interface with the
external REPO circuit must be field-supplied 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
ADVERTISSEMENT : Risque de décharge électrique pouvant causer des dommages matériels,
des blessures, et même la mort. L'action EPO de l'onduleur arrêtera le redresseur, l'onduleur et
le bypass statique, mais il ne déconnectera pas la puissance d'entrée de l'onduleur. Pour isoler
électriquement l'onduleur, une interface avec le circuit de repo externe doit être fournie sur le
terrain pour permettre la déconnexion du disjoncteur d'entrée de l'onduleur afin d'éliminer
toutes les sources d'alimentation de l'onduleur et de l'équipement connecté pour se conformer
aux codes de câblage nationaux et locaux et Règlements
Figure 4.1 on page 41, shows the location of the REPO connection inside the UPS front panel. Figure 2.5
on the next page, shows the connection details.
If a REPO connection is not required for the UPS, the factory-installed jumper between Pin 9 and Pin 10
must remain installed for the UPS to operate.
NOTE: The terminal-block wire range is 18 AWG ~ 33 AWG (0.82 mm
using 18-AWG copper, shielded, signal cable. If the REPO will trip an external, electronically-controlled
circuit breaker, you must reset the breaker before starting the UPS after the REPO is activated.
NOTE: We recommend that you route the wiring for the REPO connection from the rear of the UPS
through the built-in wiring channel to connect to the REPO port.
