2 HANDLING THE GOODS
Our products are of robust construction but require careful treatment before installation on site. This section
discusses the requirements for receiving and unpacking the goods, as well as associated considerations
regarding product care and personal safety.
Caution:
Before lifting or moving the equipment you should be familiar with the Safety
Information chapter of this manual.
2.1 RECEIPT OF THE GOODS
On receipt, ensure the correct product has been delivered. Unpack the product immediately to ensure there
has been no external damage in transit. If the product has been damaged, make a claim to the transport
contractor and notify us promptly.
For products not intended for immediate installation, repack them in their original delivery packaging.
2.2 UNPACKING THE GOODS
When unpacking and installing the product, take care not to damage any of the parts and make sure that
additional components are not accidentally left in the packing or lost. Do not discard any CDROMs or
technical documentation. These should accompany the unit to its destination substation and put in a
dedicated place.
The site should be well lit to aid inspection, clean, dry and reasonably free from dust and excessive vibration.
This particularly applies where installation is being carried out at the same time as construction work.
2.3 STORING THE GOODS
If the unit is not installed immediately, store it in a place free from dust and moisture in its original packaging.
Keep any de-humidifier bags included in the packing. The de-humidifier crystals lose their efficiency if the
bag is exposed to ambient conditions. Restore the crystals before replacing it in the carton. Ideally
regeneration should be carried out in a ventilating, circulating oven at about 115°C. Bags should be placed
on flat racks and spaced to allow circulation around them. The time taken for regeneration will depend on the
size of the bag. If a ventilating, circulating oven is not available, when using an ordinary oven, open the door
on a regular basis to let out the steam given off by the regenerating silica gel.
On subsequent unpacking, make sure that any dust on the carton does not fall inside. Avoid storing in
locations of high humidity. In locations of high humidity the packaging may become impregnated with
moisture and the de-humidifier crystals will lose their efficiency.
The device can be stored between –25º to +70ºC for unlimited periods or between -40°C to + 85°C for up to
96 hours (see technical specifications).
2.4 DISMANTLING THE GOODS
If you need to dismantle the device, always observe standard ESD (Electrostatic Discharge) precautions.
The minimum precautions to be followed are as follows:
● Use an antistatic wrist band earthed to a suitable earthing point.
● Avoid touching the electronic components and PCBs.
