2. Connect the cable to the H201Ti's terminals L1/L, L2/N and E/G. For wiring details,
see Table D-1 on page D-1.

Note: The earth/ground terminal (E/G) must be connected to the power source ground
(green wire) or directly to the transformer tank. See the special considerations regarding
grounding at the beginning of Section 6.3.8 on page 6-25.
Never perform high-voltage tests (mega-ohm measurements using a
WARNING
CAUTION
Megger* instrument) on cables connected to a 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.
