TB9400 Installation and Operation Manual General Safety and Regulatory Information 31

2.2 Equipment Safety

2.2.1 Installation and Servicing Personnel

The equipment should be installed and serviced only by qualified personnel.

2.2.2 Preventing Damage to the PA

The base station has been designed to operate safely under a wide range of

antenna loading conditions. Transmitting into a low VSWR will maximize

the power delivered to the antenna.

Important Do not remove the load from the PA while it is

transmitting.

Load transients (switching or removing the load) or atmospheric

disturbances (for example rain static and electrical storms) can damage the

PA output stage. See “Connecting RF” on page 84 for recommendations.

2.2.3 ESD Precautions

Important This equipment contains devices which are susceptible to

damage from static charges. You must handle these devices

carefully and according to the procedures described in the

manufacturers’ data books.

We recommend you purchase an antistatic bench kit from a reputable

manufacturer and install and test it according to the manufacturer’s

instructions. Figure 2.1 shows a typical antistatic bench set-up.

You can obtain further information on antistatic precautions and the dangers

of electrostatic discharge (ESD) from standards such as ANSI/ESD

S20.20-1999 or BS EN 100015-4 1994.
