Work and Equipment Safety
N
OTE
: NPT-1020 equipment is intended for installation in restricted-access areas only.
NPT-1020 platforms contain power sources of varying voltages. Note the following guidelines when
installing the platforms:
Before you start:
Ensure the integrity of the grounding connections.
Make sure that sufficient lighting is available.
Do not work on any equipment connected to a voltage source (DC or AC).
Ensure that the maximum working temperature does not exceed 70°C.
Use only insulated tools.
Wear protective clothing as required by the requisite safety regulations.
Do not install or maintain equipment connected to external lines (for example, E1 tributaries) during
thunderstorms.
Avoid contact with high-voltage sources when installing platforms, cards, and modules.
Make sure you are familiar with the warning signals and labels on the equipment and strictly observe
the procedures needed to avoid the indicated hazards.

Grounding Requirements
All the equipment, including NPT-1020 platforms, ancillary units, and equipment from other vendors, must
be properly grounded at all times. Good equipment grounding is necessary to protect personnel and
equipment, minimize noise, and allow the discharge of accumulated static charges to earth.
