Hazardous voltage
Instructions:
1. Always switch off the external group switch and the main
switch in the cabinet, before performing any installation, dis-
assembly, repair or replacement of components.
2. Do a voltage check and make sure that the electrical
power is disconnected from the system.
3. Only ABB certified technicians are permitted to commis-
sion the Terra.
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 potential harmful high voltages.
5. The installation and maintenance personnel must supply
their own lighting equipment, since the T54 has no lights in-
side the cabinet.
6. Always connect the Protective Earth (PE) first, before con-
necting the neutral (N) and Phase (P) wiring.
7. Correctly lock the door after installation or service opera-
tions.
