free environment. The site should provide for easy access to the ports of the gateway
device.This will make it easy for you to connect and disconnect cables, as well as
view the LEDs.
21 Warning: The power source for the gateway unit should be located near the unit and
should be easily accessible.
22 Caution: To allow proper cooling of the gateway device, make sure that the air flow
around the unit and through its heatsink cooling fins on the rear is not restricted.
23 Circuit Overloading: Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits might have
on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.

provoquer un danger d’explosion. La remplacer uniquement par une batterie du
même type ou de type équivalent recommandée par le constructeur. Les batteries
doivent être éliminées conformément aux instructions du constructeur.
25 Warning: For centralized DC power connection, install only in a restricted access
area.
26 A tray cable is required to connect the power source if the unit is powered by
centralized DC power. The tray cable must be a UL listed Type TC tray cable and
rated at 600 V and 90 degrees C, with three conductors, minimum 14 AWG.
