Installation Notes
This section provides notes on how to install and connect ShieldPRO and peripherals.
4.6.1.
Notes on installation location
Install ShieldPRO in a place where it can be operated properly. See "4.7 Use of ShieldPRO in an
Industrial Environment" for details.
4.6.2.
Notes on operation
1. Before connecting or disconnecting cables to/from peripherals, make sure that power to
ShieldPRO is OFF. Connecting or disconnecting cables to/from a peripheral with ShieldPRO
ON may cause a malfunction or fault to occur.
2. After turning off ShieldPRO, wait for five seconds or longer before turning the power on
again. Turning on the power immediately after turning it off may cause a malfunction or fault
to occur.
3. Clean ShieldPRO periodically.
4.6.3.
Notes on operational environment
1. ShieldPRO is VCCI Class B information technology equipment (or information equipment
mainly intended to be used in household environments) conforming to the reference level of
the Voluntary Control Council for Interference by Information Technology Equipment (VCCI).
2. If ShieldPRO is used near a radio, TV and/or wireless device, ShieldPRO may cause poor
reception. Also a device generating intense magnetic field located near ShieldPRO may
cause ShieldPRO to operate improperly. If this occurs, move ShieldPRO away from the
device.
3. To use ShieldPRO in an industrial environment, always ensure ShieldPRO meets the
conditions described in "4.3 Environmental Specification (Main Unit)".
4.6.4.
Notes on cable connections
1. Use cables authorised by NEC.
2. To connect peripheral devices to ShieldPRO, use appropriate cables with connector shapes
and signal alignments meeting those of ShieldPRO and the peripheral devices.
3. Do not pull cables forcefully or put objects on cables.
4. Install peripheral devices at locations where cables connected to the devices may not be
pulled excessively. Avoid using ShieldPRO if cables are stretched and/or objects are put on
cables.
5. Insert connectors securely. Inserting connectors loosely may cause ShieldPRO and
peripheral devices not to operate at all or operate deficiently.
