Ametek Sorensen Asterion AST Series - 1-Phase AC Input Operation; Table 2-3. AC Input Connector Type

DC Asterion Series Overview
M330460-01 Rev A 2-11
Safety-Ground
Use the GND pin (G) provided in the input AC connector or the Stud provided in the
rear panel for Safety-Ground Connection. For using the rear panel M4-0.7 x 7 stud,
use nut tightening torque is 1.1 Nm (10 lb-in) max.
Table 2-3. AC Input Connector Type
CAUTION!
To prevent damage to the AC input mating connector, follow torque specifications,
and, if a wire ferrule is used, ensure that it is properly sized and that it has been
crimped with the appropriate ferrule crimping tool.
2.8.4 1-Phase AC Input Operation
Connect the utility AC mains wires to the rear panel AC input connector terminals,
L1/L2, L2/L3, or L1/L3. Ensure that the voltage does not exceed 264 VAC. The power
source does not require a neutral connection, so the input could be between any two
lines that have a voltage that does not exceed 264 VAC. Use wires with ratings equal
to or greater than the current rating listed in the specification Section 1.2.2. A ground
wire must be connected from the rear panel safety-ground terminal or the rear panel
safety ground stud to the utility power earth protection-ground.
2.8.5 3-Phase AC Input Operation
Connect the utility AC source wires to the rear panel AC input connector terminals,
L1/L2/L3; a neutral connection is not required. Ensure that the line-line voltage does
not exceed 264 VAC. Use wires with ratings equal to or greater than the current rating
listed in the specifications Section 1.2.2. A ground wire must be connected from the
rear panel safety-ground terminal or the rear panel safety ground stud to the utility
power distribution earth protection-ground.
CAUTION!
Do not connect an AC voltage that is greater than 264 VAC, either line-to-neutral
or line-to-line, for 1-Phase or 3-Phase inputs. Exceeding the maximum AC input
voltage could result in damage to the unit.
