ACCEPTANCE TESTS
CAUTION
Power Down the relay by removing the test plugs before removing or inserting
modules. Failure to do so can permanently damage the relay.
GENERAL
This section is a guide for testing the relay. It is not necessary that the tests be performed for
incoming inspection. The relay has been tested at the factory with automated test equipment.
TEST EQUIPMENT
1. Single source of current at the rated frequency.
2. AC ammeter.
3. Continuity tester or Ohm meter.
4. Precision timer for testing timed events.
5. One VDC supply.
The specific requirements of the equipment are given in the text of this section, and in the
associated circuit diagrams.
DRAWINGS
The following drawings should he used for reference during testing. They are located in the
PRODUCT DESCRIPTION (PD) section.

EQUIPMENT GROUNDING
All equipment used in testing the SBC223 relay should be connected to a common grounding
point to provide noise immunity. This includes the current source, as well as the SBC221 itself.
The ground connection on the SBC223 is terminal
#10.

POWER UP
1. Connect the relay as shown in Figure 20. The AC input is not required for this
test; only the DC power supply voltage is required. Apply the rated DC.
2. Only the Green, ENERGIZED, LED should be on.
Note:
To perform the Acceptance Test correctly, eliminate all seal-in function by placing
jumper Ji connected to only one terminal (i.e. do not short together any terminals).
