Special Conditions for Safe Use (X):
1.The apparatus enclosure may contain light metals. The apparatus must
be installed in such a manner as to minimize the risk of impact or friction
with other metal surfaces.
2. A transient protection device can be fitted as an option, in which the
equipment will not pass the 500 V test.
