Do not reverse the ground and hot wires when connecting an
external source.
3.
Apply motor auxiliary voltage to Pin 8 (motor power input) and Pin 3 (neutral).
4.
Verify that the motor runs in the proper direction when conditions of sensed voltage
result in activation of Raise and Lower outputs.
In no case should the load current circuit be interrupted with the
regulator or transformer energized.
Do not remove auxiliary current transformers without shorting the
current inputs. Death or severe electrical shock can occur.
5.
Temporarily place a shorting device across the LDC
‑
CT secondary to short the line
drop compensator circuit, and place another shorting device to short the circulating
current paralleling output, for the load current check.

Mounting Kit only; check the Application Guide of the specific
adapter panel used for proper pin numbers.
6.
Insert an ammeter between the polarity input and Pin 4.
7.
Open the load current shorting device and with a known load on the transformer or
regulator, measure the current in the load current circuit to ensure that this current is
correct for 0.2 A full load.
