Important Safety Instructions

General Safety
DANGER!
YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to
hazards. These procedures should be performed by qualified technicians familiar with the hazards associated with this type of equipment. These hazards may include shock, energy, and/or burns. To avoid these hazards:
a) The tasks should be performed in the order
indicated.
b) Remove watches, rings, and other metal objects.
c) Prior to contacting any uninsulated surface or
termination, use a voltmeter to verify that no voltage or the expected voltage is present. Check for voltage with both AC and DC voltmeters prior to making contact.
d) Wear eye protection.
e) Use double insulated tools appropriately rated for
the work to be performed.
f) For 400V DC input systems, do not work on an
energized system without full arc flash and PPE protection.
Voltages
AC Input Voltages
DANGER! This system may operate from AC input
voltage capable of producing fatal electrical shock. AC input power must be completely disconnected from the branch circuits wiring used to provide power to the system before any AC electrical connections are made. Follow local lockout/tagout procedures to ensure upstream branch circuit breakers remain de-energized during installation. DO NOT apply AC input power to the system until all electrical connections have been completed and checked.
DC Input Voltages
DANGER! This system may operate from 400V DC input
voltage capable of producing fatal electrical shock. DC input power must be completely disconnected from the branch circuits wiring used to provide power to the system before any DC electrical connections are made. Follow local lockout/tagout procedures to ensure upstream branch circuit breakers remain de-energized during installation. DO NOT apply DC input power to the system until all electrical connections have been completed and checked.
DC Output and Battery Voltages
DANGER! This system produces DC Power and may have
a battery source connected to it. Although the DC voltage is not hazardously high, the rectifiers/converters and/or battery can deliver large amounts of current. Exercise extreme caution not to inadvertently contact or have any tool inadvertently contact an output terminal or battery terminal or exposed wire connected to an output terminal or battery terminal. NEVER allow a metal object, such as a tool, to contact more than one termination or battery terminal at a time, or to simultaneously contact a termination or battery terminal and a grounded object. Even a momentary short circuit can cause sparking, explosion, and injury.
DANGER! Follow local lockout/tagout procedures to
ensure DC branch circuit protection devices remain de­energized during installation at loads, as required.
Battery
WARNING! Correct polarity must be observed when
connecting battery leads.
WARNING! Special safety precautions are required for
procedures involving handling, installing, and servicing batteries. Observe all battery safety precautions in this manual and in the battery instruction manual. These precautions should be followed implicitly at all times.

WARNING! A battery can present a risk of electrical
shock and high short circuit current. Servicing of batteries should be performed or supervised only by properly trained and qualified personnel knowledgeable about batteries and the required precautions.
The following precautions should be observed when
working on batteries:
• Remove watches, rings, and other metal objects.
• Eye protection should be worn to prevent injury
from accidental electrical arcs.
• Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for the work to be performed. Ensure that wrenches with more than one working end have only one end exposed.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or
disconnecting battery terminals.
• Risk of explosion if battery is replaced with an incorrect type or if polarity is reversed. When replacing batteries, replace with the same manufacturer and type, or equivalent.
• Dispose of used batteries according to the instructions provided with the batteries. Do not dispose of batteries in a fire. They may explode.
• ALWAYS FOLLOW THE BATTERY MANUFACTURER’S RECOMMENDATIONS AND SAFETY INSTRUCTIONS.
In addition to the hazard of electric shock, gas produced by batteries can be explosive and sulfuric acid can cause severe burns. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes, and is toxic. If electrolyte comes into contact with skin, the affected area should be washed immediately with large amounts of water.
DANGER!
This equipment may be used in conjunction with lead-acid batteries. Working near lead-acid batteries is dangerous!
• Batteries contain sulfuric acid.
• Batteries generate explosive gases during normal
operation. Systems containing batteries should never be installed in an airtight room or space. Only install in a ventilated environment.
• Batteries are an energy source that can produce
high amounts of electrical current.
FOR THESE REASONS, IT IS OF CRITICAL IMPORTANCE THAT YOU READ THESE INSTRUCTIONS AND FOLLOW THEM EXACTLY.
WHEN WORKING WITH LEAD-ACID BATTERIES:
• Wear complete protection for eyes, face, hands, and clothing. Examples are safety goggles or face shield, a rubber apron and gloves.
• If battery acid enters your eye, immediately flush your eye with running cold water for at least 15 minutes. Get medical attention immediately.
• If battery acid contacts skin or clothing, wash immediately with soap and water.
ALERT! Performing maintenance and/or
troubleshooting procedures may interrupt power to the loads, if battery reserve is not sufficient.
Personal Protective Equipment (PPE)
The following admonishments apply to 400V DC input systems.
DANGER! ARC FLASH AND SHOCK HAZARD.
Appropriate PPE and tools required when working on this equipment. An appropriate flash protection boundary analysis should be done determine the “hazard/risk” category, and to select proper PPE.
This product is intended only for installation in a
Restricted Access Location.
Only authorized and properly trained personnel should
be allowed to install, inspect, operate, or maintain the equipment.
Do not work on LIVE parts. If required to work or
operate live parts, obtain appropriate Energized Work Permits as required by the local authority, per NFPA 70E “Standard for Electrical Safety in the Workplace”.
Hazardous Voltage
DANGER! Hazard of electrical shock. More than one
disconnect may be required to de-energize the system before servicing.
Handling Equipment Containing Static Sensitive Components
ALERT! Installation or removal of equipment containing
static sensitive components requires careful handling. Before handling any equipment containing static sensitive components, read and follow the instructions contained on the Static Warning Page.

Digital Inputs
Programmable Relay Outputs
Note:
Quick Start Guide, QS582127000 (Issue AC, December 10, 2013)

IB2 (ACU+ Interface Board) Connections (if required) (Main Bay Only)

The IB2 (ACU+ Interface Board) provides connection points for digital inputs, programmable relay outputs, and temperature probes. The IB2 interface board is mounted inside the distribution cabinet. Refer to Figure 20.
Digital Inputs and Programmable Relay Outputs
Digital input and relay output leads are connected to screw-type terminal blocks located on the IB2. Recommended torque for these connections is 2.2 in-lbs. Refer to Figure 22 for terminal locations. Refer to Table 1and Table 2 for pin-out information.
Connect up to eight (8) digital inputs to the IB2. Note that you must supply both paths for the digital input (either a positive or negative signal and the opposite polarity return path). Observe proper polarity. Refer to Figure 22 for terminal locations and Table
1 for pin-out information.
The digital inputs can be programmed to provide an alarm when the signal is applied (HIGH) or removed (LOW). Refer to the ACU+ Instructions (UM1M820BNA or UM1M820DNA400) for programming information.
Digital Input Ratings: Refer to the following.
a. Maximum Voltage Rating: 60V DC.
a. Active High: > 19V DC.
b. Active Low: < 1V DC.
The digital inputs may be preprogrammed for specific functions. Refer to the configuration drawing (C-drawing) supplied with your system for your system’s specific configuration.
The IB2 provides eight (8) programmable alarm relays with dry Form-C contacts. Connect up to eight (8) relay outputs to the IB2. Refer to Figure 22 for terminal locations and Table 2for pin-out information.
Refer to the ACU+ Instructions (UM1M820BNA or UM1M820DNA400) for programming information.
Relay Ratings: Refer to the following.
The relays may be preprogrammed for specific functions. Refer to the configuration drawing (C-drawing) supplied with your system for your system’s specific configuration.
Temperature Probes
Each temperature probe consists of two pieces that plug
together to make a complete probe. See SAG582127000 for part numbers and descriptions.
Temperature probes are connected to the IB2 (ACU+ Interface Board) and/or optional EIB (ACU+ Extended Interface Board) mounted inside the distribution cabinet. See Figure 22 and Figure
24.
Up to two (2) temperature probes can be connected to the IB2. Up to two (2) additional temperature probes can be connected to the optional EIB. Any combination of the four (4) temperature probes can be programmed to monitor ambient temperature and/or battery temperature. A temperature probe set to monitor battery temperature can also be used for the rectifier battery charge temperature compensation feature, or the battery charge temperature compensation feature can be programmed to use the average or highest value of all battery temperature probes. The battery charge temperature compensation feature allows the controller to automatically increase or decrease the output voltage of the system to maintain battery float current as battery temperature decreases or increases, respectively. Battery life can be extended when an optimum charge voltage to the battery with respect to temperature is maintained. A temperature probe set to monitor battery temperature can also be used for the BTRM (Battery Thermal Runaway Management) feature. The BTRM feature lowers output voltage when a high temperature condition exists to control against battery thermal runaway.
The temperature sensor end of the probe contains a tab with a 5/16” clearance hole for mounting.
A temperature probe programmed to monitor battery temperature should be mounted on the negative post of a battery cell to sense battery temperature. A temperature probe used for battery charge temperature compensation and/or BTRM (Battery Thermal Runaway Management) should also be mounted on the negative post of a battery cell. A temperature probe programmed to monitor ambient temperature should be mounted in a convenient location, away from direct sources of heat or cold.

Customer Defined
Digital Input Function
-48V is factory wired to the Digital Input #8 (-) terminal for your convenience and function predefined for ESTOP. Customer­furnished system ground applied to terminal Digital Input #8 (+) activates the ESTOP function. The ESTOP function shuts down and locks out the rectifiers or 400V DC input converters, opens the LVD’s, and shuts down the optional -48V to +24V DC converters. When the ESTOP signal is removed, LVD’s close (if battery present) and -48V to +24V DC converters restart. To restart the rectifiers or 400V DC input converters; turn input power to the rectifiers/converters OFF, wait 30 seconds or more (until the LEDs on the module extinguish), then turn input power to the rectifiers/converters ON. Rectifiers/converters can also be restarted from the ACU+ LCD or WEB Interface menu (via the Rectifier Reset or Converter Reset command, found in the Manual menu in the LCD menus or under the Rectifier or Converter Control Tab in the WEB Interface).

Installing Rectifier or Converter Modules into Spec. No. 588705000 Module Mounting Shelves

Rectifier or converter modules are installed in a 588705000 module mounting shelf, depending on the shelf ordered.
• Rectifiers are installed in 588705000 List 21, List 22, 31, and 32 shelves.
• Converters are installed in 588705000 List 40, List 41, and 42 shelves.
Rectifier or converter modules can be inserted or removed with power applied (hot swappable).
The rectifier or converter module locks into the module mounting shelf through a latch located on the underside of the module. The
latch and module handle are interactive. Push the handle into the module’s front panel, and the latch will pop out from the module bottom. Click the handle to pop it out from the module’s front panel, and the latch will retract back into the module. The latch mechanism is shown in Figure 52.
WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position when installing or
removing a module. NEVER hold the handle in the closed position when installing a module into a shelf.
hand side of the shelf. The second three-phase input feeds the modules on the right-hand side. To maintain phase balance, install rectifier modules in groups of three; that is, fill all three mounting positions on the left and/or all three on the right.
PROCEDURE
1. Unpack the rectifier or converter modules.
2. If present, remove blank cover panels from the module mounting positions into which modules are to be installed.
3. Place the module into an unoccupied mounting slot without sliding it in completely.
4. Click the module handle in order to pop it forwards out of the module’s front panel (this will also retract the latch mechanism located on the underside of the module).
5. Push the module completely into the shelf.
6. Push the handle into the front panel of the module. This will make the latch lock the module securely to the shelf.
7. Repeat the above steps for each module being installed in the system.
8. After the modules are physically installed in the mounting shelf(s), they are ready for operation immediately after power is supplied to them.
One three-phase input feeds the three rectifier modules on the left-

Installing the Rectifier and Converter Modules into Spec. No. 588705300 Module Mounting Shelves

Rectifier and converter modules can be inserted or removed with power applied (hot swappable).
Rectifiers modules can be installed in any mounting position of each module mounting shelf. Converters modules can be installed in any of the three far right mounting positions of each module mounting shelf. See Figure 53.
Each rectifier and converter module locks into the module mounting shelf by means of a latch located on the bottom of the module. The
latch and module handle are interactive. Pushing the handle up into the module’s front panel causes the latch to extend to the locking position; pulling the handle down out from the module’s front panel causes the latch to retract. See Figure 53.
WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position when installing or
removing a module. NEVER hold the handle in the closed position when installing a module into a shelf.
PROCEDURE
1. Unpack the modules.
2. Note the model number located on the front of each module. Model numbers starting with the letter “R” are rectifier modules. Model numbers starting with the letter “C” are converter modules.
3. Place the module into an unoccupied mounting position without sliding it in completely. Rectifiers modules can be installed in any mounting position of each module mounting shelf. Converters modules can be installed in any of the three far right mounting positions of each module mounting shelf. See Figure 53.
4. Loosen the captive screw on the module’s handle. Pull the handle down out from the module’s front panel (this will also retract the latch mechanism). See Figure 53.
5. Push the module completely into the shelf.
6. Push the handle up into the module’s front panel. This will lock the module securely to the shelf. Tighten the captive screw on the handle.
7. Repeat the above steps for each module being installed in the system.
8. After the modules are physically installed in the mounting shelf(s), they are ready for operation immediately after power is supplied to them.
