Installation; Receipt Of Relays; Mounting; Electrostatic Discharge - Toshiba G1IF1 Instruction Manual

4. Installation

4.1 Receipt of Relays

On receiving the G1IF1, carry out the acceptance inspection immediately. In particular, check for
damage during transportation, and if any is found, contact the vendor.
Always store the unit in a clean, dry environment.

4.2 Mounting

Refer to Appendix A for details of mechanical fixings.

4.3 Electrostatic Discharge

CAUTION
The printed circuit board (PCB) within the G1IF1 is not intended to be a removable module. Do
not remove the PCB from the unit case, since electronic components on the PCB are very
sensitive to electrostatic discharge. If it is absolutely essential to take the PCB out of the case, do
not touch the electronic components and terminals with your bare hands. Additionally, always
put the PCB in a conductive anti-static bag when storing it.

4.4 Handling Precautions

A person's normal movements can easily generate electrostatic potential of several thousand
volts. Discharge of these voltages into semiconductor devices when handling electronic circuits
can cause serious damage, which often may not be immediately apparent but the reliability of the
circuit will have been reduced.
The electronic circuits are completely safe from electrostatic discharge when housed in the case.
Do not expose them to risk of damage by removing the PCB unnecessarily.
The unit incorporates the highest practicable protection for its semiconductor devices. However,
if it becomes necessary to remove the PCB, precautions should be taken to preserve the high
reliability and long life for which the equipment has been designed and manufactured.
CAUTION
 Before removing the PCB, ensure that you are at the same electrostatic potential as the
equipment by touching the case.
 Handle only the edges of the PCB. Avoid touching the electronic components, PCB
surface or connectors.
 Do not pass the PCB to another person without first ensuring you are both at the same
electrostatic potential. Shaking hands achieves equipotential.
 Place the PCB on an anti-static surface, or on a conducting surface which is at the same
potential as yourself.
 Do not place the PCB in a polystyrene tray.
It is strongly recommended that detailed investigations on electronic circuitry should be carried
out in a Special Handling Area such as described in the IEC 60747.
