Hardware Installation
b.
Tighten the wire-clamp screws to prevent the wires from coming loose.
• PW1 and PW2 support power redundancy and reverse polarity protection.
• Accepts a positive or negative power source but PW1 and PW2 must apply to the same mode.
• If both power inputs are connected, the ES8510 is powered from the highest connected voltage.
• The ES8510 can emit an alarm if PW1 or PW2 are no longer receiving power. See the
discussion on
2.
Connect a ground wire between the chassis and earth ground using
12-24AWG wire to ensure that the ES8510 is not damaged by noise
or electrical shock.
a.
Loosen the chassis ground screw on the bottom of the ES8510.
b.
Insert the ground wire.
c.
Tighten the ground screw after the earth ground wire is
connected.
Connect the Digital Input s and Relay Outputs
The ES8510 provides two digital inputs and two digital outputs (dry relay output) on terminal block
connectors on the bottom of the unit. The fault conditions can be configured in the web user interface or
Command Line Interface (CLI) and include:
•
DI State
•
Power failure
•
Ethernet port link break
•
Dry output
•
Ping failure
•
Super Ring failure
You can configure events using one of the ES8510 user interfaces (
on Page 110) or the Command
Line Interface (
The Digital Input pin can be pulled
high or low so that the connected
equipment can actively drive these
pins. The web user interface allows
you to read and set the value to the
connected device. The power input
voltage of logic low is 0 to 10VDC and
logic high is 11 to 30VDC. Do not apply
a higher voltage than the specification;
it may cause internal circuit damage
or a cause an incorrect DI action.
