4 PRE-INSTALLATION
Cable installations must be preplanned to ensure a
successful installation. It is important to ensure that
personnel are properly trained and qualified for the
specific task they are performing. All applicable rules and
regulations including federal, state / provincial, local, and
municipal laws must be followed. For further information
on installing MI cables, contact nVent Technical Support,
see Section 1.1.
4.1 Minimum Installation Temperature
A minimum installation temperature of −40°F (−40°C) is
recommended for MI cables.
4.2 Precautions
When installing PYROTENAX MI industrial wiring cables,
all appropriate precautions should be followed, including
OSHA and other applicable national safety regulations.
Therefore, in addition to observing standard safety
practices, observe the following:
•
Take reasonable precautions to prevent damage to the
cable from severe blows with sharp instruments and
pulling over sharp objects.
•
Do not pull cables around corners that have sharp
edges, such as corners in cable trays, or other
obstructions.
•
Pull all cable diameters, one at a time, by hand.
•
Hand feed cables around corners using large sweeping
bends.
•
When changing direction from horizontal to vertical,
use properly-sized sheaves or pulleys.
•
Protect exposed cables from any nearby or overhead
work that could damage the cable.
•
Do not pull cables around a radius smaller than the
minimum pulling radius (see Table 2, page 18).
•
Make sure all equipment used during cable installation
is in good operating condition.
