When all connections have been double checked, remove any lockout/tag outs, and

unit is now ready for operation.
3.4.5 Mains Connection
The Main Power connection is designed for a mains cable which contains the mating
connector (included with your ST Power Supply) for the input on the HVPS side. A
suitable mains cable will have the following characteristics:
Four-conductor (3P+G) 10AWG (6 mm2) for 208V models, or
Five-conductor (3P+N+G) 12AWG (4 mm2) for 400V models.
Minimum 600V rating
Recommended: Flame-retardant, with resistances to abrasion, chemicals, oil, sunlight
and weather.
Input Voltage Selection.
Before the HVPS may be installed, it is critical that the
input AC line voltage being supplied to it conforms to
the marking on the rear panel. No neutral connection
is required for 208VAC units. The HVPS is not
sensitive to phase rotation. Double check your power
line wiring configuration before proceeding with the
installation.
Mains power.
Improperly grounded devices can be extremely
dangerous in the event of a fault. Use three-wire
mains or extension cables with protective ground
only. Hookup the mains cable into wall sockets with
protective ground only
