Exchange Procedure
During PEM exchange, it is not necessary to set the handle switch. If you want to inform the
shelf management software of the PEM exchange, you can set the handle switch. If not, you can
leave the handle switch set to the Closed position during the exchange procedure.
1. Put on an ESD wrist strap.
2. Connect the strap to the shelf by attaching the front or rear ESD jack.
3. Turn off the feed power to the PEM being removed.
Personal Injury through Electric Shock and Burning
Touching the PEM power input terminals with metallic objects on your hands, wrists, or
hanging from your neck may lead to amputations. Do not wear any metallic attire or
commodity on your hands, wrists, or hanging from your neck when working at the power
input terminals or power input cables. Be extremely careful when you use electrically
conductive tools near the PEMs.
Short Circuit and Personal Injury through Electrical Shock
Ensure that the power feeds you plan to remove or attach are powered off and cannot be
switched on while you are working.
Ensure that all power input lines are not energized.
Personal Injury
PEMs will get hot. Touching a hot PEM can cause injuries. Let the PEM cool down before
pulling it out with bare hands.
