Chapter 2 Installation
2.1 Announcements before installation
Power supply must be off during installation and wiring.
Serious damage to the equipment may be caused by misconnection of power
supply terminals, improper connection of in-out lines and output line short circuit.
Therefore, before turning on the power supply, check the connection of input output
grounding and power supply wire.
Grounding terminal of E21 digital control device must be grounded in correct way,
with low impedance lower than 0.3Ω.
Do not dismantle the device without authorization so as to avoid malfunction.
Electrical components inside the digital device are very sensitive to static electricity,
therefore do not put foreign matters or make them fall to the inside of digital control
device or touch the control circuit.
Please install E21 digital control device in safe region. Avoid high temperature, and
direct sunlight, moisture and splash of oil drops or water.
Do not use this device in place of high temperature, moisture condensation, dust,
oil smoke, conductive dust, corrosive gas or flammable gas.
2.2 Installation space and direction
Generally, E21 bending machine digital control device is embedded on control panel,
keep a distance of 65mm from its neighboring components and damper (shell) on up
and down, right and left, to facilitate operator install and maintain the device.
2.3 Installation environment
Place free from water, vapor, dust or oily dust.
Place free from flammable, explosive or corrosive gas.
Place free from interference of strong electromagnetism or noise.
Ambient temperature is between 0℃- 40℃. When ambient temperature is over
40℃, please put it in well-ventilated place.
Relative humidity is under 90%RH.
