Input Power Connection
DANGER:
• As supplied, the SED2 must be grounded (per IEC
536, Class 1, NEC and other relevant industry
standards). Extremely hazardous conditions can occur if
the SED2 is not correctly grounded.
• Use only permanently wired input power connections.
Only hard-
wired input power connections are permissible.
Use Class 1 60/75° copper wire only.
• The cross-section of the ground-bonding conductor must
be at least equal to the input power cables.
• The following terminals can carry hazardous voltages
even when the SED2 is not running:
− Input power terminals: L1, L2, L3
− Motor terminals: U, V, W
− Link terminals: DC-, DC+/B+, DC/R+, B- (not for
customer use)
Connect input power to SED2 terminals L1, L2, and L3 (Figures 19
through 22).
