- Cut off 125 Vdc customer power and 70 Vdc contact supply, discharge residual voltage and take ESD protection before board removal or installation, to prevent component damage from static electricity.
- During unit overhaul, test relay operation and contact resistance of the 2-out-of-3 voting circuit. Inspect backplane connectors for oxidation and loose contacts.
- Perform full trip loop test after replacement. Confirm correct 2-out-of-3 voting logic before returning the unit to service.

Q1: What is the difference between IS200ECTBG1A and IS200ECTBG2?
A: IS200ECTBG1A is only for redundant EX2100 excitation control system, it supports 2-out-of-3 relay voting trip circuit. IS200ECTBG2 is designed for simplex control, no 2-out-of-3 voting function. These two boards cannot be cross-replaced.
Q2: Does IS200ECTBG1A have built-in surge suppression for inductive loads?
A: No. The board does not come with internal surge suppression. Customers must install external suppression components for inductive load circuits to protect relay contacts and avoid false tripping.
Q3: What test should be carried out after replacing IS200ECTBG1A on site?
A: After installation, complete trip loop commissioning test is required. Verify the 2-out-of-3 relay voting logic. Confirm all trip and lockout signals work normally before putting the unit back into operation.
