Wiring Requirements

WARNING

Do not disconnect modules or wires unless power has been

switched off or the area is known to be non-hazardous. The

devices may only be connected to the supply voltage shown on

the type plate. The devices are designed for operation with a

Safety Extra-Low Voltage. Thus, they may only be connected to

the supply voltage connections and to the signal contact with the

Safety Extra-Low Voltages (SELV) in compliance with IEC950/

EN60950/ VDE0805.

ATTENTION

This unit is a built-in type. When the unit is installed in another

piece of equipment, the equipment enclosing the unit must

comply with fire enclosure regulation IEC 60950/EN60950 (or

similar regulation).

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your Moxa EtherDevice Switch.

Calculate the maximum possible current in each power wire and

common wire. Observe all electrical codes dictating the

maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could

overheat, causing serious damage to your equipment.
