5
This SANT411152.068-05 OM Operation Manual contains brief information about CE208 S7 multifunctional
single-phase electric meter (hereinafter referred to as the "Meter"). Complete information on the above meter is
contained in SANT411152.068-05 UM User Manual, which can be found at the manufacturer's website:
http://www.energomena.ru/ru/products/meters/ce208-all.
When learning about the meter and operating it, you must be additionally guided by SANT411152.068-03 DS
Data Sheet (supplied with the meter) and SANT.411152.068-05 UM User Manual.
Only persons who have received special training for working with voltages up to 1000 V and who have studied
the Operation Manual are allowed to work with the meter.
1 SAFETY REQUIREMENTS
1.1 The insulation between all current and voltage circuits connected together and with the “ground” can
withstand a voltage of 4 kV AC at 50 Hz for 1 minute. During the test, the leads of the electrical test output device,
the interface circuits are connected to the "ground" (the "ground" is a conductive foil film enclosing the meter and
attached to a flat conductive surface on which the meter base is mounted).
1.2 The insulation between all current and voltage circuits connected together and with the "ground" can
withstand pulse voltage of 6 kV. During the test, the leads of the electrical test output device must be connected to
the "ground".
1.3 Insulation resistance between the casing and electrical circuits, at least: 20 MΩ — under conditions of
