ELECTRICAL CONNECTIONS section of the Installation Instructions (IM582137000) for a complete procedure.
DANGER! Adhere to the “Important Safety Instructions” presented at the front of this document.
There are several options to provide AC inputs to the 588705300 module mounting shelf. See PD588705300.
1. For factory installed module mounting shelves without plug-in AC input connectors, AC input leads are factory connected
from the module mounting shelf AC input terminals to an AC input termination assembly provided in the system/cabinet.
Refer to the system/cabinet documentation for connection details to the AC input termination assembly. Refer to the
system/cabinet documentation for recommended AC input branch circuit protection.
2. For a field installed module mounting shelf in a system with a List 27 distribution cabinet or if a List 7 distribution cabinet
system is used in a relay rack and not a system cabinet, the module mounting shelf is equipped with plug-in AC input
connectors located on the rear of the shelf. AC input cable assemblies with mating connectors are available (see Power Data
Sheet PD588705300). Refer to Power Data Sheet PD588705300 for recommended AC input branch circuit protection. See
PD588705300 and Figure 6.

5.6.3 IB2 (Controller Interface Board) Connections (if required)
The IB2 (Controller 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 7or Figure 8.
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 10 for terminal locations. Refer to Table 1and Table 2for pin-out information.
Digital Inputs
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 10 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
Controller Instructions (UM1M820BNA or UM1M830BNA) for programming information.
Digital Input Ratings: Refer to the following.
a) Maximum Voltage Rating: 60 VDC.
b) Active High: > 19 VDC.
c) Active Low: < 1 VDC.
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.
ESTOP Function
If an ESTOP switch is wired to the IB2-1 Controller Interface Board, customer-furnished system ground applied to terminal DI8+
activates the ESTOP function. The ESTOP function shuts down and locks out the rectifiers, shuts down and locks out the optional -
48 VDC to +24 VDC converters, and opens the optional low voltage disconnect (LVD) contactors (battery and load type). If the
system has battery connected and does not contain a battery LVD or the controller power option is set to Battery Pwr (jumper J4 on
the system interface board is set to Battery Pwr), the controller will remain operational. If the system does not contain battery or load
LVD(s) and has battery connected, the loads will be sustained by the battery voltage.
For Systems NOT Containing a Battery LVD: When the ESTOP signal is removed, LVD contactors (battery and load type) will close
after the “LVD Reconnect Delay” has elapse (customer configurable via the controller) if battery voltage is present on the bus.
Rectifiers and -48 VDC to +24 VDC converters will remain off. The rectifiers will restart when the input power is removed and
restored after 30 seconds or more (until the LEDs on the modules extinguish). To restart the -48 VDC to +24 VDC converters:
remove the converter, wait 30 seconds or more (until the LEDs on the converter extinguish), then re-insert the converter.
For Systems Containing a Battery LVD: When the ESTOP signal is removed, LVD contactors (battery and load type) will remain open.
Rectifiers and -48 VDC to +24 VDC converters will remain off. The rectifiers will restart when the input power is removed and
restored after 30 seconds or more (until the LEDs on the modules extinguish). When the rectifiers restart, LVD contactors (battery
and load type) will close after the “LVD Reconnect Delay” has elapse (customer configurable via the controller) and the -48 VDC to
+24 VDC converters will restart.
NOTE! If a customer-furnished method to disconnect the input power to the system is not provided, the rectifiers will stay
locked OFF until the input power is recycled. If the ESTOP signal is removed without recycling the input power, the rectifiers
will remain off and have a local alarm visible on the module. The ESTOP alarm from the controller will extinguish. The
controller will not issue an alarm for this condition.

12
Programmable Relay Outputs
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 10 for terminal locations and Table 2for pin-out information.
Refer to the Controller Instructions (UM1M820BNA or UM1M830BNA) for programming information.
Relay Ratings: Refer to the following.
a) Steady State: 0.5 A @ 60 VDC; 1.0 A @ 30 VDC.
b) Peak: 3 A @ 30 VDC.
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
NOTE! Each temperature probe consists of two or three pieces that plug together to make a complete probe. See
SAG582137000 for part numbers and descriptions.
Temperature probes are connected to the IB2 (Controller Interface Board) and/or EIB (Controller Extended Interface Board) mounted
inside the distribution cabinet.
Up to two (2) temperature probes can be connected to the IB2. Up to two (2) additional temperature probes can be connected to the
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.
