Never perform high-voltage tests (mega-ohm measurements
using a Megger* instrument) on cables connected to an H201Ti
or a Hydran 201Ci Controller. Never apply high voltages to the
components of a Hydran 201i System, as they are equipped
with surge protection devices that could be damaged by
Megger* tests.
When fastening the CPU module, ensure not to bend the pins of
the connector located between the CPU and I/O modules.
