BURN HAZARD
The shunt resistors can reach temperatures in excess of 350
°
C
(662
°
F). Do not handle a shunt module that has been operational until
it has cooled sufficiently.
Combustible materials above the shunt module or its enclosure may
need the protection of a metal plate to shield them from the heat.
Failure to observe these precautions could result in damage to
surrounding materials, possibly leading to a fire or personal injury.
ATTENTION
The shunt resistors release large amounts of heat. When mounted
inside an enclosure, you must provide adequate ventilation so the
maximum ambient temperature of 50
°
C (122
°
F) is not exceeded.
Failure to observe this precaution could result in damage to the
module.
