Preparing the Meter for Installation
The following steps should be taken before inserting an I/O card into an
9510 / 9610 meter:
C
AUTION
The components inside the meter are extremely sensitive to electrostatic discharge. Wear an anti-static
wrist strap at all times when working inside the unit. Failure to use proper equipment during servicing will
void the meter’s warranty.
1.
Turn off all power to the meter.
2.
Open all PT fuses (or direct voltage input fuses). Close all CT shorting blocks.
3.
Disconnect the Line and Neutral (or DC power) wires from the Control Power
inputs of the unit.
4.
Disconnect all other wiring (or power off all other circuits) which may present
potentially hazardous voltage levels to the unit, such as connections to the relay
outputs, status inputs, etc.
5.
Ensure that all cables still connected to the meter are
NOT
live.
Installing the I/O Card
The I/O card consists of a circuit board with an attached polarized CHAMP
connector on the component side. Follow these steps to install the I/O card:
1.
If present, remove the plastic tab that seals the I/O card’s cover plate to the
meter. Use the Phillips screwdriver to remove the plate’s two screws, then
remove the plate.
2.
Hold the I/O card by the sides and slide it into the base unit with the component
side facing up. Slide the edge of the circuit board down the slots along each side
of the chassis.
3.
Align the CHAMP connector with the socket and press the I/O card firmly into
place. The socket and the connector are polarized, so the pins in the connector
will not fit into the socket if the card is not oriented correctly. The I/O card is
securely inserted into the socket when the backplate of the I/O card meets the
chassis of the meter.
4.
Ensure the cover meets the chassis of the base unit. Use the Phillips screwdriver
to replace the two backplate screws with their lock-washers. They must be
installed firmly to preserve transient immunity.
5.
Reinstall the Line and Neutral (or DC power) wiring to the Control Power inputs
of the unit.
6.
Reconnect all other wiring (or re-enable all other circuits). Close the PT fuses (or
direct voltage input fuses), and open the CT shorting blocks.
7.
Turn on power to the meter and verify the correct operation of the unit.
