(2) Check components for possible damage.
2.2. Installation
2.2.1. Installing the controller
Turn OFF power
Before touching any terminal on the rear of the meter or if there is a
possibility of touching it, turn OFF the vacuum gauge power and the power
applied to the setpoint output terminal. Contact with the terminal, to which the
voltage (24 VDC) is applied, will cause electric shock if power is turned ON.
Turn OFF power
Before touching the power terminal on the rear of the controller or if there is a
possibility of touching it, turn OFF the power to the vacuum gauge. Contact
with the terminal, to which the voltage (24 VDC) is applied, will cause electric
shock if power is turned ON.
Ventilation
Do not plug the air vents of the vacuum gauge controller. If the air vents are
plugged, heat will be contained inside and the gauge may be damaged. The
gauge will not indicate normal values either.
Keep out foreign matter
If foreign matter like metal fragments or combustibles are admitted into the
vacuum gauge through the air vents or other openings, remove them.
Otherwise, the vacuum gauge may be damaged.
Install the controller to the panel. Fig. 11 shows the panel cut drawing.
2.2.2. Installing the meter
Fig. 12 shows the panel cut drawing (A-type).
Secure a space for installing the cable on the back of the meter.
Install the meter in a position where the meter terminals do not come into contact with other
components and parts when the gauge is in operation.
