Ensure that GROUP A COMMON and GROUP B COMMON are always properly connected.
Verify that the terminals for GROUP A COMMON and GROUP B COMMON are tightened with the tightening torque of 7.0 N.m.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Each output group is equipped with an internal, replaceable 8 A fuse (250 V, 5x20 mm, Time Delay/Slow Blow).

The individual outputs must be fused separately.

CAUTION

INCORRECT OR MISSING FUSING

Provide a separate, external 2 A fuse for each individual output.
