Safety
Grounding
For the highest electrical safety the EL326 switches are provided with several grounding
points. First, there are two green ground
screws (see images) that attach directly to
the switch case. These screws can be used
to provide a NEBS compliant safety ground.
Please follow all the NEBS grounding rules
and your own local requirements (which are
not documented in this manual) to ensure
the safe operation of the switch.
Alternatively, the power plug has a chassis
ground terminal (#4) that can be used to
safety ground the switch. This terminal is
internally tied to the switch case. In addition,
there is a ground terminal for each power
input. Use these to terminate the ground wire
for each of your power inputs.
Note: The 2 Safety Guard Screws are designed to
be used with Ring Lug Terminals. Do not wrap ground wire around either of the safety ground
screws.
Warning: It is recommended that you make your safety ground connections first before
connecting any power to the switch. Make sure that all power is off before making any
power or ground connections to the switch.
