2.3. Single UPS installation
Installation and wiring must be carried out in accordance with the local
electric laws and regulations by trained professionals.
Step 1. Make sure that the mains wire and breakers of the building are
rated for the capacity of the UPS to prevent electric shock or risk of fire.
NOTE!
Do not use the wall receptacle as the input power source for the UPS, as its rated
current is less than the UPS’s maximum input current. The receptacle may be
damaged and destroyed.
Step 2. Switch off the mains switch in the building before installation.
Step 3. Turn off all the connected devices before connecting to the UPS.
Step 4. Prepare wires based on the following table:
