Precautions Regarding Handling
This section explains precautions which should be observed when handling the GOT
@DANGER
0 Before beginning any installation or wiring work, make sure all phases of the power
supply have been obstructed from the outside. Failing to completely shut out the
power supply phases could cause electrical shock and/or damage to the product.
0 Following installation or wiring work, when turning on the power supply and operating
the equipment, make sure the terminal cover provided as an accessory has been
attached to the product. Failing to attach the m e r could result in electrical shock.
A
CAUTION
0 Be careful never to let foreign matter such as filings or wiring scraps get inside the
module. These can cause fire, breakdowns, and malfunctioning.
0 Communications cables should not be bundled with main circuits and power lines, or
installed in the vicinity of these.
0 The communications cable should be connected securely to the connector on the
communications module, and checked after being installed, to make sure it is not
loose. Defective contact could cause malfunctioning.
0 Make sure the memory cassette is installed securely in its connector. After connecting
the connector, check to make sure it is securely tightened and not loose. Defective
contact could cause malfunctioning.
0 The FG and LG terminals should always be grounded using the Class 3 ground de-
signed especially for the Graphic Operation Terminal, or a higher class of ground.
Failing to ground these terminals sufficiently could cause electrical shock and/or mal-
functioning.
0 Before wiring the GOT, check the rated voltage and terminal layout of the wiring, and
make sure wiring is done correctly. Connecting a power supply that differs from the
rated voltage, or wiring it incorrectly, could cause fire and/or breakdowns.
0 Tighten terminal screws to the rated torque.
Failing to tighten terminal screws adequately could cause short-circuits, fire, and/or
malfunctioning.
