- If you are unable to take either of the above precautions, touch a
conductive part of the equipment chassis with your other hand before
touching ESD sensitive components.
- Always hold the boards by the edges and avoid touching the
component contacts.
F.3 Regulatory Compliances
This equipment complies with the standard listed in Table 27.
F.3.1 DC Power Conditions for Use
These conditions must be met by the customer installation for the unit to
be considered safe in DC power application:
- DC power as rated on the label or in the manual; 28V 1V
- Temperatures: -20°C to +55°C (-4°F to 131°F)
- In order to satisfy CE Mark safety requirements, the system integrator
must provide a means of removing power to the unit without the use
of a tool. Common options to meet the requirement are:
- Install a quick disconnect box located within view of the panel.
- Use a power cord with a fuse holder that can be opened without
a tool. The panel has a 5 A fuse internally, so an 8 A, 125 V fuse
on the cord would not interfere with operation.
- To guarantee immunity and emissions performance, the power cable
should be shielded with a minimum shielding of 85% optical
coverage. The shield should make 360 degrees/circumferential
electrical contact with the metal case of the connectors at each end. If
this is not possible, ferrites maybe necessary to block noise from
entering the panel to achieve acceptable emissions performance.
Power and ground cables should also be twisted and able to carry a
maximum of 1.0 A total.
