CAUTION: Before you connect power to the JSA3800 appliance, attach the
ground wire in one of the below configurations to meet the safety
requirements and to ensure proper operation:
• Both power supply ground terminals
•
One or both of the chassis ground terminal(s) located to the left of the
power supply modules
• Both power supply ground terminals
You connect DC source power to the JSA3800 appliance by attaching power cables from
the external DC power sources to the terminal studs on the DC power feed faceplates.
WARNING: DC-powered JSA3800 appliances are intended for installation
only in restricted access locations.
WARNING: Before you perform the following procedure, ensure that power
is removed from the DC circuit. To ensure that all power is off, locate the
circuit breaker on the panel board that services the DC circuit, switch the
circuit breaker to the OFF position, and tape the switch handle of the circuit
breaker in the OFF position.
To connect the DC source power to the JSA3800 appliance:
1.
Ensure that the input circuit breaker is open so that the voltage across the DC power
source cable leads is 0 V, and so that the cable leads will not become active while
you are connecting DC power.
2.
Connect the stripped and twisted wires to the wire clamps under the DC terminal
screws on the back panel of the JSA3800 appliance.
NOTE: The red cable should be connected to the V+ terminal, and the
black cable should be connected to the V- terminal, respectively.
3.
Use the terminal screws to secure the power source cables to the power feed on the
JSA3800 appliance by attaching the twisted wires that are attached to the cables to
the appropriate terminals.
4.
Attach the plastic safety cover.
