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).
