Safety-4
■Do not place anything on the Unit.
Do not place any metallic object such as a small pin or a paper clip, or any container with a liquid such
as a vase or a flower pot, on the Unit. Liquid or metallic objects falling into the Unit could result in a
fire or electric shock.
Do not place optional devices or objects on the Unit. They may slip and cause injury. Also, it may
cause the device to malfunction, by the weight of the object placed on it.
■Use the Unit only with the indicated power supply setting.
Do not use the Unit at any voltage other than the indicated voltage. Doing so could result in a fire or
electric shock.
In addition, make sure the power outlet is compatible with your voltage and power cords. Note that
using other outlets carries a risk of electric shock.
■Ensure that the capacity for incoming current to the distribution board is greater than the
operating current of the circuit breaker.
Ensure that the capacity for incoming current to the distribution board is greater than the operating
current of the circuit breaker. If it is not, the circuit breaker might not operate properly in the event of a
failure, which could result in a fire.
■Ground the Unit.
●When using an AC (PoE) model, redundant power model (with an AC power supply module
installed), and an EPU, use only a grounded power outlet. Failure to do so might not only result in
electric shock, but it might also introduce unwanted electrical noise that could cause a Unit failure.
●When using a DC model and a redundant power model (with a DC power supply module installed),
connect a ground cable to ground the Unit. Failure to do so might not only result in electric shock,
but it might also introduce unwanted electrical noise that could cause a Unit failure.
■For DC electric power equipment, use upstream and downstream-insulated items.
With DC power sources, use upstream and downstream-insulated items that carry no risk of electric
shock. Uninsulated electric power equipment may carry the risk of electric shock.
■Mounting and removing the DC power cable must be done by a trained technician or
maintenance personnel.
Mounting and removing the DC power cable must be done by a trained technician or maintenance
personnel. Terminal connections are required for connection of the DC power cable to the power
facility. For this reason, incorrect handling of the DC power cable could result in fire or electric shock.
