AUXILIARY OUTPUT DESIGN GUIDELINES FOR RELAY ACTIVATION

•

The auxiliary output is polarity sensitive (TB2-1 is positive and TB2-2 is negative).

CAUTION

Polarity reversals can damage the auxiliary output.

CAUTION

Use minimal torque on the terminals of TB2 to avoid damage.

•

It is highly recommended to use a 24 V dc external voltage source.

•

Transient suppression diodes must be used with inductive loads such as electromechanical relays.
