Power Connections
NOTE: Power must be supplied from a dedicated source with a disconnect
switch.
See Figure 3-2.
The customer power source must be wired in accordance with either the
National Electric Code, Part I or the Canadian Electrical Code, Part I, or
local codes. At a minimum, 10 AWG 600 volt wire is required unless
superseded by local codes. Four #10−32 studs provide for line connection.
Refer to the system controller ID plate for the input voltage and verify the
transformer tap wiring using Tables 3-1 and 3-2. Measure the incoming
power source voltage from the main power supply. Incoming voltage
transients shall not exceed 150 volt amplitude and have a frequency content
of less than 500 Hz.
S The power line input is three phase (three wire with ground).
S Refer to Table 3-1 for the T1 and T2 high-voltage transformers. Each
has a terminal block with H1, H2, and H3 terminals.
S Refer to Table 3-2 for the T3 control transformer.
S All transformers must be wired for the same input voltage.

Refer to Tables 8-2 and 8-3 in the Specifications section for current demand
during normal full-power operation. Size supply wiring and circuit breakers
or fuses to allow for heavy current draw during startup.
To connect power to the system controller, remove the voltage cover on the
back of the enclosure. Connect power wiring to the terminals labeled A (L1),
B (L2), C (L3), and Ground.
