Inspect the package for damage. If damaged, notify the appropriate 

carrier immediately. If undamaged, open the package and inspect 

the device for obvious damage. Return damaged products.

Warning:

Do not use on oxygen service, in an explosive/hazardous

environment, or with flammable/combustible media.

Disconnect power supply before installation to prevent

electrical shock and equipment damage.

Make all connections in accordance with the job wiring

diagram and in accordance with national and local

electrical codes. Use copper conductors only.

Caution:

Use electrostatic discharge precautions (e.g., use of wrist

straps) during installation and wiring to prevent equipment

damage.

Avoid locations where severe shock or vibration, excessive

moisture or corrosive fumes are present.

Do not exceed ratings of the device.
