Installation Cautions
1. To protect the wiring from rats, all wires should be placed in pipes. It is recommended to use PVC
conduits or galvanized tubes. Although the control panel has a good anti-static, anti-lightning,
and anti-leakage design, it is important to ensure that the case of the control panel and the AC
ground wire are connected perfectly and the AC ground wire is grounded.
2. It is recommended not to plug and unplug connection terminals frequently when the system is
energized. Be sure to unplug the connection terminals before starting any relevant welding job.
3. Do not detach or replace any control panel chip without permission because unprofessional
operation may cause damage to the control panel.
4. It is recommended not to connect any other auxiliary devices without permission. All non-routine
operations must be confirmed with our engineers in advance.
5. A control panel should not share one power socket with any other large-current devices.
6. It is preferable to install card readers and buttons at a height of 55 inches to 59 inches (1.4m to
1.5m)
above the ground, subject to proper adjustment according to customers’ usual practice.
7. It is advised to install the product in a place convenient for future maintenance, like a weak
electric well
.
8. The exposed part of any connection terminal is strongly recommended not be longer than 0.16
inches (4mm). Professional clamping tools may be used to avoid short-circuit or communication
failure resulting from accidental contact with excessive exposed wires.
9. To save access control event records, exterminal data periodically from control panels.
10. Prepared countermeasures against unexpected power failure, like
selecting power supply with
UPS.
11. If the RS485 reader is connected externally and shares the power supply with the device (The
control panel does not supterminal RS485 readers with fingerprint verification function), the
connection between the EXT RS485 terminal and the reader is recommended
not to be longer
than 328 ft (100m). Otherwise, it is recommended to use a separate power supply for the reader.
12. The length of the connection between computer and elevator controller: RS485 communication is
less than 3937 ft (1200m). In order to make the communication more stable, it is recommended
to control
within 2624 ft (800m)
. It is recommended to use the power supply delivered with the
system as the control panel power supply.
13. It is recommended to use the power supply delivered with the system as the control panel power
supply.
14. In a place with strong magneticinterference, galvanized steel pipes or shielded cables are recommended,
and proper grounding is required.
