Precautions
Ensure that the rack is correctly and securely installed to prevent it from falling or becoming unstable.
Dangerous voltage in excess of 240VAC is always present while the Power Supply Module is plugged into an
electrical outlet. Remove all rings, jewelry, and other potentially conductive material before working with this
product.
Never insert foreign objects into the chassis, the power supply, or any other component, even when the
power supply is turned off, unplugged, or removed.
Ensure that the main power is fully disconnected from the gateway by unplugging all power cords from their
outlets. For safety, verify that the power outlets and plugs are easily reachable by the operator.
Do not handle electrical cables which are not insulated. This also includes network cables.
Keep water and other fluids away from the gateway to minimize electrical hazards.
Comply with electrical grounding standards during all phases of installation and operation of the product. Do
not allow the gateway’s chassis, network ports, power supply, or mounting brackets to contact any device,
cable, object, or person attached to a different electrical ground. Also, never connect the device to external
storm grounding sources.
Perform installation or removal of the chassis or any module in a static-free environment. Proper use of anti-
static body straps and mats is strongly recommended.
