3 Installation
Exercise caution when using tools.
⚫
If the installation position of the device is higher than the shoulders of the installation
⚫
personnel, use a vehicle such as a lift to facilitate installation. Prevent the equipment from
falling down and causing personal injury or damage to the equipment. When a ladder is
used, ensure that another person holds the ladder steady to prevent accidents.
⚫ Wear ESD gloves and remove conductive objects, such as jewelry and watches.
⚫ At least four persons are required to move the device. When moving a device, keep your
back straight and move smoothly to avoid any injury.
⚫ Do not use mounting ears as the holding points when moving the device. Otherwise, the
device may be damaged or slipped.
