3.2. 3.2. 3.2. 3.2. Safety Requirements
3.2.1. 3.2.1. 3.2.1. 3.2.1. Basic Safety Requirements
To ensure the normal operation of the equipment and the human safety, please strictly obey the
following security instructions during the operation:
„ Carefully operate the equipment in accordance with the instructions given in this
manual.
„ Turn off the power before the equipment installation.
„ Confirm whether the power supply is connected.
„ Connect the power supply to a grounded socket to meet the European safety
standards.
„
Try not to place the power supply socket far away from the power inlet of the
equipment, so that the power socket can be directly turned off without removing
the power cable connected to the equipment in the case of power supply failure.
„ Avoid any liquid contacting the equipment, lest short circuits or current leakage
be caused.
„ Never place the equipment near any heat source, lest the operation performance
of the equipment be deteriorated or even the equipment be damaged. In
addition, avoid direct sunshine on the equipment.
„ Clean the equipment with soft and clean dry cloths and do not use any
detergents.
„ Do not wear any loose dress or jewelry (such as rings, necklace and bracelet).
Preferably the sleeves should be rolled during the operation. Make sure that the
installation of the switch on the rack will not entangle your clothes.
3.2.2. 3.2.2. 3.2.2. 3.2.2. Antistatic Requirements
Many antistatic measures have been taken for 3P@C 4450E. However, if the static electricity in the
environment exceeds a certain range, it will cause damage to the circuits or even the whole
equipment; therefore, static electricity should be taken into account during the design of the
equipment room environment. The static induction comes from two aspects: 1) outside electric
field, such as high voltage power transmission lines and lightning stroke; 2) internal system, such
as indoor environment, floor materials and equipment structure.
Therefore, in order to avoid the damages caused by static electricity, please make sure to:
„ Ground the equipment and the floor well;
„ Keep the equipment room inside dust-proof;
„ Maintain appropriate temperature and humidity conditions;
„ The human static electricity can also damage the printed circuits and the internal
components. Therefore, when you touch the circuit board or the extended
module, please hold the edges of them instead of directly touching the circuits or
components to avoid damage to them caused by human static electricity. Where
necessary, wear an antistatic wrist strap and antistatic work uniform during the
operation.
