8.4.2 ALARM I/O FIELD INSTALLATION INSTRUCTIONS
The installation kit will come with the following components:
Qty. Part # Description
1 22845-XX* ALARM I/O Relay Board
1 31666 1 ft. (305mm) Communication cable
1 33456 Wiring Shield
4 32678 Spacers
4 03237 Nuts, 6-32
* - XX-Multiple options available, see SECTION 17 for proper option number.
Follow the instructions below to install the ALARM I/O Relay Board into the charger:
1. De-energize both AC and DC power from the charger.
2. To see how the ALARM I/O Relay board mounts to the SCR Driver Board and the cable
hookup, see FIGURE 8.4.4-1. (All RJ45 connector sockets are in parallel, so it will work with
the cable in any location.)
3. Install the four nylon spacers into the SCR Driver board on the inner panel of the charger.
4. Put the wiring shield on the bottom two nylon spacers.
5. Mount the ALARM I/O Relay board on the four nylon spacers as shown.
6. Install the four nuts on the nylon spacers and tighten. (Do not over-tighten nuts or the nylon
spacers will strip.)
7. Connect the communication cable from the SCR Driver board RJ45 connector socket to the
ALARM I/O Relay board RJ45 connector socket.
8. Fold the wiring shield under the front of the charger base edge by the circuit breaker if
possible.
8.4.3 WIRING THE ALARM I/O BOARD TO EXTERNAL CIRCUITS
1. Route the wiring for your external circuits into the charger through one of the spare conduit
knockouts on the DC side of the enclosure. See SECTION 6.3. Make sure to isolate this
wiring from the charger AC input and DC output power wiring. The wiring shield is to help
isolate these wires from the other wires. Do not place in the same knockout as either the AC
input or DC output wiring.
2. Use #26-14 AWG wire stripped 0.25 in. (6mm) on the end going into the Individual Alarm
Terminal Blocks. Torque all connections to 5 inch pounds (.6Nm). All terminal blocks are
labeled in the non-alarm or fault condition.
3. Make sure to observe the Alarm Relay Contact Rating on FIGURE 8.4.4-2 when wiring into
external circuits.
4. Secure all wires with a strain relief in the conduit knockout so they will not to be pulled out of
unit. Protect the wires to ensure the sharp edges of the opening will not damage the wire.
5. Return power to the charger.
8.4.4 TESTING THE ALARM I/O RELAY BOARD AND EXTERNAL CIRCUITS
1. It is recommended that a test be performed after installation to make sure everything works
as intended.
2. Go into the TECH MENU on the charger control board by pressing the RIGHT ARROW, then
LEFT ARROW buttons, and repeat this sequence 4 times while in the default display mode,
then enter the TECH MENU code which is set to “0001”. (For additional information on the
TECH MENU see SECTION 12.2.)
3. The first display in the TECH MENU is the control board version and date.
4. Press the DOWN ARROW button and you can get to the following menus: Relay Start, LEDs
are off, and Disp (Display voltage mode).
5. Go to the Relay Start Menu. This menu will only be available if the charger has an optional
ALARM I/O Relay Board that is functioning.
6. Press the RIGHT ARROW button at the “Relay Start” display. The ALARM I/O Relay Board
LEDs and Relay Contacts will go through a test cycle to verify they are working properly.
7. If you press the RIGHT ARROW button while the display shows “Relay Stop”, the test will
stop.
8. You can restart the test anytime the display shows “Relay Start”.
9. To exit the TECH MENU, press the LEFT ARROW button.
10. The charger is ready for service if all of these tests verify that it functions properly.
