Replacing the Power Supply

This section contains instructions for removing and re-installing the Power Supply module for both
metal and plastic carriers.
WARNING:
Never remove the power supply without first turning off the power switch and
I
disconnecting the power cord from the AC outlet.
Beware of hazardous voltages; whenever the carrier connections are exposed, use
I
extreme caution; do not touch them directly or with any type of tool. Follow all procedures
carefully.
Do not install the power supply unless the carrier is connected to an approved ground.
I
Before touching leads, connectors, pins, and other components, use a properly grounded
I
wrist strap, to prevent damage from electrostatic discharge (ESD). The wrist strap can be
clipped to the ground screw or plugged into the hole next to the ground screw.
Do not attach any cables or power cords to the power supply until it is installed in the
I
carrier.
Do not power up the control unit until all of the modules and power equipment are
I
installed. Failure to comply with this procedure can result in shock hazard and/or damage
to the equipment.
CAUTION:
Grounding circuit continuity is vital for safe operation of the MERLIN MAGIX system. Never
operate with grounding conductor disconnected. The ground-screw connection is located on
the carrier.
Removing the Power Supply Module (Metal Carrier)
Follow these steps to install the power supply module in the carrier:
1. If possible, back up system programming on a floppy disk or memory card.
See "Backup" in Programming Basics for instructions on backing up to a floppy disk.
I
See Appendix D, "Backing up with a Memory Card" for instructions on backing up to a
I
PCMCIA card.
If the basic carrier's power supply fails, you cannot back up system programming.
