Current flow during RUN when the bypass contactor bypasses the RSV-DN.
Current transformers CT1 and CT2 are able to measure motor current, thus the motor current
protections of the RVS-DN are operable.
Note:
If the RVS-DN is bypassed without using the preparation for bypass the following protections are not
operable
during RUN:
• UNDER CURRENT
• O/C SHEAR PIN
• OVERLOAD TRIP
3.5.1.2 Maintaining Current Protection after Bypass Closes - RVS-DN 950-3000a
RVS-DN 950-3000A models are supplied without preparation for bypass. However bypass must be applied
for these models.
Current transformers CT1 and CT2 are supplied separately and must be connected to the RVS-DN as shown
below.
Note:
Do not ground current transformers secondaries!
Current flow during RUN when the bypass contactor bypasses the RVS-DN. The customer
must perform the bypass connections shown.
Current transformers CT1 and CT2 are supplied with the RVS-DN. Do NOT ground the CTs!
