ORDERING INFORMATION

INSTALLATION

Inspection: 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.

Requirements:

•Installer must be a qualified, experienced technician.

•Tools (not provided):

-Digital Volt-ohm Meter (DVM)

-Appropriate screwdriver for mounting screws

-Appropriate drill and drill bit for mounting screws

•Appropriate accessories

•Three #8 self-tapping mounting screws (not provided)

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.

•Do not exceed ratings of the device.
