5.3 UPS replacement with ModularEasy
5.3.3 9PXMEZ11Ki
•
After opening the UPS I/O terminal blocks cover of the faulty UPS, check if hazardous voltage is no
longer present on UPS terminal blocks by using an electrical safety tester
•
Disconnect the ModularEasy power cables, and the ModularEasy detection cable of the faulty UPS
•
Reconnect immediately the ModularEasy power cables, and the ModularEasy detection cable to a new
UPS. If It is not possible to reconnect the ModularEasy power cables immediately, link their 3 wires
together (line and neutral wires connected to ground wire) to prevent an electrical shock and reconnect
them to a new UPS later.
Hazardous voltage and lost load risk: do not manipulate the ModularEasy
manual bypass switch unless the ModularEasy power cables are connected
to UPS terminal blocks.
