Overview 2
1. Overview
The ACC402 Energy Pack is used exclusively with the
CPE330 RX3i CPU. It preserves user memory in the
Controller during power fluctuations or outages.
If system power is lost, the Energy Pack maintains power
long enough for the connected CPE330 to write its user
memory contents to non-volatile memory. When system
power is restored, the user memory is restored if the
CPE330 is configured to power up from RAM.
The ACC402 Energy Pack is connected to the
IC695CPE330 CPU via a dedicated cable IC695CBL002
(shown above). This arrangement allows the Energy Pack
to source power from the RX3i backplane in order to
charge its circuitry. The cable also allows the CPU to
monitor the status of the Energy Pack. Upon loss of
backplane power, the CPU automatically switches over
to the Energy Pack power source, ensuring an orderly
power-down sequence.

Hardware Installation 8
Over tightening the mounting screws could crack the
plastic housing.
Installation Location
This product is intended for use with the RX3i system. Its
components are considered open equipment (having
live electrical parts that may be accessible to users) and
must be installed in an ultimate enclosure that is
manufactured to provide safety. At a minimum, the
enclosure shall provide a degree of protection against
solid objects as small as 12mm (e.g. fingers). This
equates to a NEMA/UL Type 1 enclosure or an IEC60529
IP20 rating providing at least a pollution degree 2
environment. For details about installing RX3i rack
systems, refer to PACSystems RX3i System Manual,
GFK-2314.
If you need technical help, contact Technical Support.
For phone numbers and email addresses, see the back
cover of this Guide.

3. Cable Connections
Figure 3.1: Cable Connection
Connecting to the Energy Pack
The two connectors on the ACC402 Energy Pack mate
with the corresponding two pre-wired pig-tailed
connectors of the IC695CBL002 cable assembly. Insert
each keyed connector as shown above and secure using
the captive screws provided.

Connecting the Energy Pack to
the Controller
With power to the CPE330 Controller turned off, connect
the 7-pin keyed connector of the IC695CBL002 cable
assembly to the mating connector on the underside of
the IC695CPE330 and secure using the captive screws
provided.

Grounding 13
4. Grounding
Proper grounding of this device is essential. The included
ground strap wire must be pressed onto the spade lug
connector on the left side of the ACC402. Cable assembly
IC695CBL002 ties all internal cable shield drains to this
ground.
The frame ground wiring used by both the CPE330 and
ACC402 must be connected to a central ground point.
The green and yellow ground strap wire (see figure 3.1),
which attaches to the spade lug on the side of the
ACC402 base plate, must be connected to the central
ground point.
All ground wires from the host rack or panel must be as
short as possible and terminated at the same grounding
point.

Power-up 14
5. Power-Up
When power is applied to the Energy Pack, the power-up
process goes through the following steps:
1. The IN LED turns on green.
2. The Energy Pack performs a self-
diagnostic test. If this test passes,
output power to the Controller is
turned on and the OUT LED turns
on (green).
3. Charging of the Cap Pack begins
and the STAT LED blinks green.
4. When charging of the Cap Pack is complete, the STAT LED
turns on solid green and the Energy Pack signals to the
controller that it can start run-time operation. The
Controller will not start running its application until the
Energy Pack signals that it is fully charged.
5. If the Energy Pack is faulty or is not communicating, the
Controller will commence operations after a timeout period
(90 sec).

7. Firmware Updates
The firmware for the Energy Pack is automatically
updated by the Controller. At power-up, the Controller
checks the version of Energy Pack firmware to verify
compatibility with the Controller firmware. If an update
is needed, the Controller performs it automatically.

Replacing the Cap Pack Module 17
8. Replacing the Cap Pack Module
The status of the Energy Pack is provided at %S0014
(#PLC_BAT) and %SA0011 (#LOW_BAT). User programs
should monitor these status bits in order to alert for
maintenance conditions. Refer to PACSystems RX3i CPU
Reference Manual, GFK-2222V or later.
The Cap Pack may be removed and replaced while power
is applied to the Energy Pack (hot swapped.)
When
hot
swapping Cap Packs, do not cycle power until the new
Cap Pack is fully charged and operational. Cycling power
before the STAT LED is solid green can result in Controller
memory not being preserved. Do not hot remove/insert
the Cap Pack during the firmware update process.
1. Loosen the four screws on the Cap Pack and carefully
pull the Cap Pack off the base.
2. Install the new Cap Pack on the base, first engaging
the module-to-base connectors and then pressing
the Cap Pack into place.
