2 Installation
2.1 Annoucements 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.
