Important safety information

To prevent loss of life or physical injury, observe the safety guidelines in this

section.

Power lines

Exercise extreme care when working near power lines.

Working at heights

Exercise extreme care when working at heights.

Grounding and protective earth

The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is

the user’s responsibility to install the equipment in accordance with national

regulations. In the USA, follow Section 810 of the

National Electric Code, ANSI/NFPA

No.70-1984

(USA)

. In Canada, follow Section 54 of the

Canadian Electrical Code

. These

codes describe correct installation procedures for grounding the outdoor unit, mast,

lead-in wire and discharge unit, size of grounding conductors and connection

requirements for grounding electrodes. Other regulations may apply in different

countries and therefore it is recommended that installation of the outdoor unit be

contracted to a professional installer.

PIDU

Always use the Cambium Power Indoor Unit Plus (PIDU Plus PTP 300/500/600 Series)

to power the ODU. Failure to use the Cambium supplied PIDU could result in

equipment damage and will invalidate the safety certification and may cause a safety

hazard.

Alternative DC supplies

If an AC supply is not required or an additional back up DC supply is required, the DC

supply is connected to the PIDU DC IN terminals. This is the only method of supplying

external DC to the ODU. The DC supply must comply with the following requirements:

• The voltage and polarity is correct and is applied to the correct PIDU terminals.

• The power source is rated as Safety Extra Low Voltage (SELV).

• The power source is rated to supply at least 1A continuously.

• The power source cannot provide more than the Energy Hazard Limit as defined by

IEC/EN/UL60950-1, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA).
