Emergency Power Off

DANGER
ENERGIZED BY EXTERNAL POWER SOURCES When emergency power off (EPO) is activated, the rectifier modules no longer supply the load. The load and system are still energized by the batteries (unless the battery breaker is also tripped by the EPO). Hazardous voltages are still present at some circuits, terminals and switches even when the EPO is activated (unless disconnected from the upstream supply with a separate EPO). Failure to follow these instructions will result in death or serious injury.

ENERGIZED BY EXTERNAL POWER SOURCES

When emergency power off (EPO) is activated, the rectifier modules no longer supply the load. The load and system are still energized by the batteries (unless the battery breaker is also tripped by the EPO).

Hazardous voltages are still present at some circuits, terminals and switches even when the EPO is activated (unless disconnected from the upstream supply with a separate EPO).

Failure to follow these instructions will result in death or serious injury.

According to UPS safety standard IEC 62040-1, a UPS with an emergency switch device should be able to prevent further supply of the load.

The emergency switching device interrupts the load via a terminal to an externally connected switching device.

EPO in a Gutor Modular DC Charger with internal battery: The EPO will switch off the modules and trip the internal battery breaker.
EPO in a Gutor Modular DC Charger with external battery: The EPO will switch off the modules. The disconnection of the external batteries needs to be handled by the customer.
NOTE: Optionally, with external batteries the internal battery breaker (if installed) can be selected to trip if the EPO is activated.
