The optional Auxiliary Alarm Relay PC Board (A5), mounted inside the
separate top enclosure (penthouse), provides two (2) form-C contacts
(TB4-1 through TB4-36) for each of the following individual alarms:
• High DC Voltage
• Low DC Voltage
• DC Output Failure
• AC Input Failure
• Ground Fault Detection (positive or negative)
• Summary (common) Alarm
Alarm contacts (TB4) are as follows, shown in non-alarm condition:

PROCEDURE
1. Deenergize and lock out all ac and dc voltages to the AT10.1.
2. Allow internal voltages to dissipate, then check with a voltmeter.
3. Remove the top panel from the penthouse enclosure (on top of charger).
4. Route your remote annunciator wiring into the penthouse enclosure through
one of the unused knockouts on the side of the enclosure.
5. Connect the wiring (use #22-14 AWG) to the appropriate terminals of TB4
on the Auxiliary Relay Relay board (as shown in the figure above). Strip
each wire 0.25in / 6.4mm, and securely tighten the terminal screws.
6. Replace the top panel on the penthouse enclosure and restart the AT10.1.
NOTES
1. Alarm contacts are rated at 0.5A / 125 Vac or Vdc.
2. Terminal block (TB4) is compression type, accepting #22-14 AWG wire.
3. Terminals are labeled in non-alarm condition.
