POWER CORD PLUGS
All 208/240/480V power supplies are shipped with a single-phase power cord and plug. To operate
as a three-phase unit, the user must obtain a power cord and plug that is certified by national or local
electrical codes. The plug should be connected to the power cord by a licensed electrician.
All 200/230/400V and 400V CE power supplies are shipped with a three-phase power cord and no
plug. The user must obtain a plug that is certified by national or local electrical codes. The plug should
be connected to the power cord by a licensed electrician.
POWER CORDS
If the power cord needs to be changed, use the tables below to choose the proper wire size for the
appropriate length cord. Note that the input current used to determine the cord size is I
1eff
. In the U.S.,
use a 3-conductor SO type cord for single-phase, and a 4-conductor SO type cord for three-phase power
supplies. In other countries, use cords that are certified by national or local codes. Prepare the power
cord wires as shown in Fig. 3-6 for non-CE power supplies, or Fig. 3-6a for CE power supplies. Note that
all 4 wires must loop through the toroid in the CE power supply. Cap or tin the conductor leads and use a
#10 terminal on the ground wire. The cord should be installed only by a licensed electrician.
