8.6 What To Do With Defective Relays

If you cannot correct a problem with the relay using the procedures described in this manual, then return the complete relay to the manufacturer in secure, appropriate packaging. If available, use the original packaging to avoid damaging the relay.

8.7 Storing Relays That are Taken Out of Service

Store the relay in a dry, clean room. The temperature range for storage of the relay or associated spare parts is -13°F to 131°F (-25°C to +55°C). Refer to the technical specifications in Reference D of this manual for more storage information.

If the relay is de-energized and stored for an extended time period, proper voltage should be applied to the power input for one or two days prior to placing the relay into service.
