Personal Injury
Touching the PEM power input terminals with metallic objects on your hands, wrists, or
hanging from your neck may lead to severe injuries through electric shock and burning.
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
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. Be careful with the used tools in order to
prevent a short circuit.
