Caution
To ensure correct installation and grounding, install the bridge
in compliance with your local and national electrical codes:
National Fire Protection Association (NFPA) 70, National
Electrical Code (U.S.); Canadian Electrical Code, Part 1, CSA
22.1 (Canada). If local or national electrical codes are not
available, refer to IEC 364, Part 1 through Part 7 (other
countries).
Warning
Never defeat the ground conductor or operate the equipment
in the absence of a suitably installed ground conductor.
Contact the appropriate electrical inspection authority or an
electrician if you are uncertain that suitable grounding is
available.
Before You Install the Bridge
Prior to installing a bridge system, develop a preinstallation checklist that
covers all aspects of the installation. A well-developed plan identifies
potential problems early so that they can be solved before the installation
process begins.
