7. MEMORY CASSETTE AND BATTERY
7.1.2 Handling precautions
This section explains the specifications of the memory cassette, the handling precautions
and the installation and removal procedures.
(1) Since the memory cassette and pin connector are made of resin, do not drop them or
apply heavy impact to them.
(2) Do not remove the printed board of memory cassette from the case. Doing so could
give damage to the module.
(3) Carefully prevent foreign matter such as wire chips from entering the inside of the
memory cassette.
If it does get inside the module, remove it immediately.
(4) When installing the memory cassette into the CPU module, fully press it to the
connector.
(5) Do not place the memory cassette on a metal object where current is or can be
leaked, or materials like wood, plastic, vinyl, fibers, electric wires or paper where
static electricity is charged.
(6) Do not touch the lead of the memory. This may damage the memory.
(7) Do not touch the CPU connector of the memory cassette. Doing so may cause poor
contact.
IMPORTANT
(1) Before installing the memory cassette to or removing it from the CPU module,
make sure that the power is OFF. Installing or removing the memory cassette
with power ON destroys its memory.
(2) The RAM memory in the CPU module (parameters, T/C set values, main
program, MELSECNET/10 network parameters) is not overwritten even if the
CPU module is powered ON with the E
2
PROM memory cassette installed.
If the RAM memory is needed, back up the data using a peripheral device
before installing the memory cassette.
(3) Memory cassette cannot be installed to the CPU module.
