3. Operation Check

Check the operation of the SmartSlot Rela

I/O Module before final

installation. Note: The UPS will not protect the load durin

this proce-

dure.

1. Check the output relays by temporarily installing the SmartSlot

Relay I/O Module into the SmartSlot. See section 4 for informa-

tion on installing the SmartSlot Relay I/O Module in the Smart-

Slot. Attach the supplied screw terminal connection board.

2. Turn on the UPS. Wait for a few seconds for the SmartSlot Relay

I/O Module to initialize. Use a digital multimeter or continuity

checker to confirm that all N. O. (normally open) output contacts

are open and that all N. C. (normally closed) contacts are shorted.

Measure resistance from each common contact to the correspond-

ing N. O. and N. C. contacts. Short circuit resistance should be

near 0 Ohms, while open circuit resistance should be greater than

1 megaohm.

3. Remove the SmartSlot Relay I/O Module from the SmartSlot and

confirm that all outputs have changed states—that all N.O. con-

tacts are shorted and that all N. C. contacts are open with respect

to their common contacts.

4. Turn the UPS off. Check the inputs by temporarily installing the

SmartSlot Relay I/O Module into the SmartSlot. Attach the sup-

plied screw terminal connection board.

5. Short circuit input #1 to one of the ground contacts on the screw

terminal connection board. Confirm that the UPS turns on.

Note:

Valid SmartSlot Relay I/O Module inputs require continuous

assertion for at least one second.

6. Short circuit input #2 to ground. Confirm that the UPS turns off.

7. Turn the UPS on and wait for the self-test to complete. Short cir-

cuit input #3 to ground. Confirm that the UPS performs a self-test.

8. Disconnect the UPS from the AC power source. Short circuit

input #4 to ground. Confirm that the UPS enters sleep mode (this

requires from 20 to 600 seconds, depending on internal UPS set-

tings). Reconnect the AC power source to the UPS.
