INSTALLING THE AT10.1

Auxiliary Relay Board (optional)

The optional Auxiliary Alarm Relay PC Board (A5), mounted on the right

side panel of the circuit breaker bracket, 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 plexiglas safety shield.

4. Route your remote annunciator wiring into the enclosure through one of the

unused conduit knockouts on the side of the enclosure.

5. Connect the wiring (use #22-14 AWG) to the appropriate terminals of TB4

on the Auxiliary Alarm Relay board (as shown in the figure above). Strip

each wire 0.25in / 6.4mm and securely tighten the terminal screws.

6. Replace the safety shield 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.

4. For a detailed view of the optional Auxiliary Alarm Relay PC Board (A5),

refer to drawing (JE5030-29) listed in Appenix C on Page 80.
