Safety-5
Observe the specified stripping length of the sheath for the power cable.
 When using a DC −48 V power cable for a redundant power model, adjust the
stripping length of the sheath for the power cable (the Switch end) to 8 to 10 mm.
 If the striping length is too short, connection might fail or the cable might become
disconnected. Conversely, if the length is too long, the core will be exposed, risking
electric shock.
Do not use the Switch with the protection cap removed.
 Do not remove the protection cap except when attaching a cable. Using the Switch
with no protection cap could result in a fire or electric shock.
 Note that the following label is affixed near the standby power connector due to the
high output power of EPU-B.
Handle power cables carefully.
 Do not place anything heavy on a power cable. Do not pull, bend, or modify a cable.
Doing so could damage the cable, resulting in a fire or electric shock. If the power
cable is covered by a carpet, it is easy to forget that the cable is there and to place
something heavy on it.
 Use the supplied or a designated power cable. Using another power cable could result
in a fire or electric shock. Do not use a power cable supplied with a product other
than this product. Doing so could result in a fire or electric shock.
 If the power cable is damaged so that the wires underneath the covering are visible or
cut, stop using it, and ask maintenance personnel to replace it. Discontinue using the
cable to avoid the risk of a fire or electric shock.
 Make sure the power plug is free of dust, and insert the plug completely up to the base
of the prongs, so that it is not loose. Using a power plug with dust on it or one that is
imperfectly connected could result in a fire or electric shock.
Do not overload the power outlet.
 Do not overload the power outlet by connecting multiple power plugs to the same
outlet. Overloading the outlet could result in fire or the circuit breaker tripping due to
excessive power used, which can then affect other equipment.
Remove the power cable when installing or removing a power supply unit.
 When installing or removing a power supply unit, remove the power cable from the
power supply unit. If the power cable is connected and the power switch is turned off,
power is still supplied to some circuits. Because of this, if you install or remove a
power supply unit with the power cable connected, a fire or electric shock could
result.
