3.1.3 Electrostatic Discharge Safety Measures
For the avoidance of failures caused by electrostatic discharge, we strongly recommend to:
1. Put on esd belt, shoes or wrist strap to prevent electrostatic charge accumulation (for the wrist strap,
ensure that it fits snugly to the skin) and to ground the cable before starting to work with the equipment.
3.2 TAU-72.IP/TAU-36.IP Installation
1. If the device was exposed to low temperatures for a long time before installation, leave it for 2 hours at
ambient temperature prior to operation. If the device was exposed to high humidity for a long time, leave
it for at least 12 hours in normal conditions prior to turning it on.
2. Mount the device. The device is intended to be installed into 19’ rack using the mounting set or mounted
on the horizontally oriented perforated shelf.
If the device is being installed into a closed non-ventilated cabinet with volume less than 180l per device,
device performance will not exceed 0.8 Erlang per subscriber unit.
3. Ground the case of the device after installation. This should be done prior to connecting the device to the
power supply. An insulated multiconductor wire should be used for earthing. The device grounding and the
earthing wire section should comply with Electric Installation Code. The earth bonding point is located at
the right bottom corner of the rear panel, see Fig. 5.
3.2.1 Opening the case
First power TAU-72.IP/TAU-36.IP off, disconnect all cables.
