All wires must be braided, PVC and galvanized pipes are acceptable so that mice do not bite wires and cause failures. Although controller has a good anti-static design, lightning protection and leakage protection, make sure that controller case and AC ground wire are securely connected, and AC ground wire is really grounded. It is not recommended to frequently connect and disconnect terminals while power is on. Be sure to disconnect terminals before performing related welding work. Do not disassemble or replace controller chip without permission, unprofessional operations may damage controller. Do not connect controller and other high current equipment to same outlet.
The installation height of card reader and button is 1.45 m above ground. This height can be increased or decreased accordingly according to user's habits.

Pay attention to terminal's standard wiring, and do not leave metal part too long, so as not to cause a short circuit and communication failure.
