Deif AAL-2 Quick Start Manual

Quick start guide
AAL-2 insulation monitor
Installation
1. Make sure the AAL-2 is correctly configured for the specific application.
2. For the auxiliary supply, connect the terminals to the correct voltage.
3. Connect PE to ground and P to a phase. If it is a 3-phase network, then you can connect any of the phases to
P.
High-voltage MEGGER
If a high-voltage MEGGER is used, the ALL-2 must be disconnect at terminal P before tests are done.
Failure to do so may result in damage to the AAL-2.
Test
Test the AAL-2 in accordance with IEC 61557-8 as shown in the wiring diagrams below. Use ¼ W resistance and
set the switch ratings in accordance with the network voltages.

Adjustment of the set point
Use the potentiometer located on the back of the AAL-2 to adjust the warning set point. The potentiometer is in
the upper left corner. If a precise warning is necessary, connect a known resistor equal to the required setting
between P and PE. Adjust the potentiometer until the warning LED is activated.
Typical setting
Warning set point: 22 kΩ at 1 M range or 220 kΩ at 10 M range. Position the red marker pointer at the set point.
