Connection to a 3-phase outlet is required on sites where the system voltage
between any one of the phases and neutral is 100-127V and the voltage between
any two of the phases is 200-240V. Before connecting to any 3-phase outlet, please
refer to a qualified electrician who understands your particular installation and the
local safety and wiring regulations. Under no circumstances should the 8400 switch-
mode power supply units be operated without the green/yellow safety earth conduc-
tor connected to the building safety earth conductor system. Each power unit is
equipped with an input supply filter whose reference ground conductor is the chas-
sis. Failure to connect the green/yellow safety earth conductor to the correct earth/
ground building reference is a safety and fire hazard.

1.

Connect the LIVE (Brown) conductor on the “system 1” 8400 unit to the phase 1
(L1, RED) terminal on the 3-phase power outlet connector.

2.

Connect the NEUTRAL (Blue) conductor on the “system 1” 8400 unit.

3.

Connect the EARTH (Yellow/Green) conductor on the “system 1” 8400 unit to the
SAFETY EARTH (Yellow/Green) terminal on the 3-phase power outlet connec-
tor.

4.

Repeat 1-3 for the “system 2” power units.

NOTE: Connection between two phases in a 3-phase outlet should under no
circumstances be carried out where the single-phase voltage (the voltage
between one of the phases and neutral) exceeds 127V. The installation
should be carried out by a qualified electrician who understands your partic-
ular installation and the local safety and wiring regulations.
