2.1 Suggestions for DC power connection
The DC power source should be able to be switched off and on via an isolating switch. The unit is only
completely disconnected from the DC main power source, when the DC power cord is disconnected
either from the power source or the unit. Therefore, the DC power cord and its connectors must always
remain within reach.
2.2 Suggestions for AC power connection via external AC/DC adapter
The main power cable of the optional external AC/DC adapter serves as disconnecting device. For this
reason the outlet of the AC power source must be located near the device and be within reach.
Never place the unit under direct sunlight, near heat sources or in a humid place. Make sure the unit
has proper ventilation.
All plugs on the connection cables must be screwed or locked to the housing.
The Marine Rugged Display Computer, designed to be used in upright position with the I/O
interfaces downwards.
The unit generates heat under natural operation therefore it should be properly ventilated. Never
cover up the air intake and exhaust openings of the unit. Do not impede the fins of the heat sink.
Repairs may only be operated by specialists or technicians qualified and authorized by American
Industrial Systems, Inc.
Maintenance or repair on the open unit may only be operated by specialists or technicians qualified and
authorized by American Industrial Systems, Inc. who are familiar with the related hazards.
When accessing the internal components, users must switch off the unit and disconnect it from the
power source.
Only original accessories (or suggested optional parts) approved and supplied by American Industrial
Systems, Inc. can be used.
Assumption of safe operation is no longer possible:
-
If the unit has obvious damage or
-
If the unit no longer functions accordingly.
Under such cases the unit must be shut down and secured against any unintended operation.
2.3 Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can damage electrostatic-sensitive devices or circuit.
Adequate packaging and grounding techniques are essential fundamentals to avoid damage. The
following precautions should be always taken:
1. Deliver printed circuit boards in electrostatic-safe containers such as cartons, boxes or anti-static
bags.
2. Keep electrostatic-sensitive parts in their containers until they reach an electrostatic-free station.
3. Follow adequate grounding when sensitive PCB
’s
, components, or assemblies are in close vicinity
of the unit.
4. Store electrostatic-sensitive PCB's in a protective packaging such as insulating foam.
2.4 Grounding Methods
Protect against electrostatic damage of the unit by taking the following preventative measures:
1.
Cover workstations with approved anti-electrostatic material.
