3.2.5 Power Connector
Make sure you are using the correct power source as shown on the panel and that
no objects obstruct the airflow of the fans.
Use the following procedures to connect the Switch to a power source after you
have installed it.
Note: Check the power supply requirements in Chapter 56 on page 463, and make
sure you are using an appropriate power source.
Keep the power supply switch and the Switch’s power switch in
the OFF position until you come to the procedure for turning on
the power.
Use only power wires of the required diameter for connecting the Switch to a
power supply.
3.2.5.1 AC Power Connection
Note: This is only for the AC model of the Switch.
Connect the female end of the power cord to the power socket of your Switch.
Connect the other end of the cord to a power outlet.
3.2.5.2 DC Power Connection
Note: This is only for the DC model of the Switch.
The Switch uses a single ETB series terminal block plug with four pins which allows
you to connect up to two separate power supplies. If one power supply fails the
system can operate on the remaining power supply. Use two wires to connect to a
single terminal pair, one wire for the positive terminal and one wire for the
negative terminal.
Note: The current rating of the power wires must be greater than 20 Amps. The power
supply to which the Switch connects must have a built-in circuit breaker or
switch to toggle the power.
Note: When installing the power wire, push it wire firmly into the terminal as deep as
possible and make sure that no exposed (bare) wire can be seen or touched.
Exposed power wire is dangerous. Use extreme care when
connecting a DC power source to the device.
