5. Installation considerations
This chapter discusses items to be considered as part of installing the LCD monitor.
5.1. For your safety
Only use the product if it is in correct working order, for the intended purpose and while
keeping safety and potential dangers in mind.
•
Installation, connection, and configuration of the unit should only be carried out by
trained personnel. Unless otherwise expressly specified, this also applies to
maintenance, testing and repair.
•
Read and pay attention to the documentation. Carefully and completely read this
user manual. Always pay attention to the instructions, notes and warnings.
•
Read the safety instructions at the start of this manual.
•
Do not make modifications to the product (either hardware or firmware) without
consulting Motium. Improper modifications can cause malfunctions or damage,
and void the warranty. Motium accepts no liability for damage resulting from
unauthorised or improper modifications to the product.
•
The product is designed to be splashed with water. This includes being sprayed
with a hose. It is not designed to be submerged under water. If it is submerged
under water for long periods of time, the unit should NOT be powered on until
examined by a suitably qualified technician.
•
Observe the rated voltage. The product can be damaged or destroyed by the
application of an incorrect voltage. The product should NOT be connected to
voltages above 40 VDC. Internal protection circuitry will prevent damage from
transient voltages. Prolonged high or transient voltages applied to the unit may
cause external fuses (or the internal safety fuse) to blow.
•
Observe environmental ratings. Unsuitable ambient conditions and improper
installation (mainly due to high ambient temperature and insufficient ventilation)
may reduce the product’s life. Ensure compliance with the stated operating
conditions (see technical data), requirements at the installation site and, if
applicable, maintenance regulations.
•
No objects or liquids should be allowed to get into the product. If they do,
immediately disconnect the unit from the power supply (pull out the power plug).
•
If you notice a burnt smell or formation of smoke from a unit, immediately
disconnect it from the power supply (pull out the power plug).
5.2. Input voltage wiring
The gauge of the wire used to connect the monitor to the voltage source should be at least
22 AWG, and heavier (20 or 18 AWG) for long cable runs. At high input currents (i.e., low
input voltages), voltage drop along the wires can be significant (halving the input voltage
will double the input current – and therefore, the voltage drop across the cable). Always
use the largest practical wire size, to ensure minimum voltage drop. Section 5.5,
Power
consumption , lists the power consumption for various input voltages.
Remember, input voltage drop is the sum of current flowing in both the PWR+ and PWR-
wires. So wire resistance (and voltage drop) needs to be calculated for both wires.
