Connecting Power
The BlackDiamond 2400 W AC PSU has a power cord retainer to reduce the chance of accidental
disconnection of the cord from the PSU. The PSU has one of the following types of retainer:
● Wire retainer that rotates down over the connector and cord
● Metal clamp that attaches to the input connector on the PSU and clamps around the cord connector
Using the Wire-Style Power Cord Retainer
1 As shown in Figure 28, squeeze the sides slightly and insert the ends of the wire into the attachment
tab on each side of the power input connector.
2 Connect the AC power cord to the power input connector.
3 Rotate the retainer down over the power cord.
