Installation Guidelines
This chapter provides guidelines for installing and replacing the SA500 DC bus supply.
Instructions are included describing how to select a bus supply based on the bus
supply’s current rating and the combined current draw of the motors attached to the
bus supply through the SA500 AC Power Modules. For those installations where
greater regenerative power dissipation requires the use of a bus supply with external
braking resistors, a procedure is provided to assist in the selection of the proper
braking resistors. Refer to the wiring diagrams supplied with your system for specific
installation information.

ATTENTION: Only qualified personnel familiar with the construction and
operation of this equipment and the hazards involved should install,
adjust, operate, or service this equipment. Read and understand this
manual and other applicable manuals in their entirety before proceeding.
Failure to observe this precaution could result in severe bodily injury or
loss of life.
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power from the
DC bus supply, wait five (5) minutes and then measure the voltage at the
POS and NEG terminals of the DC bus supply and each Power Module
to ensure the DC bus capacitors are discharged before touching any
internal components. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION: Ungrounded equipment presents a shock hazard. If your
drive cabinet is mounted such that the cabinet is not grounded, a ground
wire must be connected to the cabinet for personnel safety. Failure to
observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: The user is responsible for conforming with all applicable
local, national, and international codes. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
ATTENTION: Equipment must be connected to a power source for which
it was designed. Verify that the available input is 230 VAC. Failure to
observe this precaution could result in damage to, or destruction of, the
equipment.
