DANGER
Hazardous voltage
The Terra DC Wallbox contains conductors under hazardous electrical volt-
ages. The grid terminals on the internal DIN rail may carry hazardous volt-
ages, even if all circuit breakers are switched off.
DANGER
Hazardous voltage
Instructions:
1. Always switch off the input circuit feeding the unit, (external disconnect
or breaker) before performing any installation, disassembly, repair or re-
placement of components. Follow appropriate requirements for safe work
practices, including but not limited to NFPA-70e.
2. Perform a voltage check to ensure electrical power is disconnected
from the system.
3. Only ABB certified technicians should commission the Terra DC Wallbox.
4. When the system is in an open or dangerous condition, do not allow
unqualified persons to go near it. Instruct and warn people about the po-
tentially harmful high voltages.
5. The installation and maintenance personnel must supply their own
lighting equipment because the Terra DC Wallbox has no lights inside the
cabinet.
6. Always connect the Protective Earth (PE) first, before connecting the
other power input wires.
7. Be sure to properly and securely reassemble the Terra DC Wallbox’s en-
closure after installation or service operations.
8. When handling the equipment, a proper lifting device should be used in
accordance with your local EHS policies.
