
Do not exert more than 0.5 N•m (4.5 lb-in) of torque when tightening the
installation fastener, enclosure, accessory, or terminal block screws. Tightening
the screws with excessive force can damage the plastic casing of the PS-B unit.

When installing or removing screws, ensure that they do not fall inside the PS-
B unit's chassis.
Failure to follow these instructions can result in injury or equipment damage.
CAUTION
STATIC SENSITIVE COMPONENTS
PS-B unit internal components, including accessories such as RAM modules and
expansion boards, can be damaged by static electricity.

Keep static-producing materials (plastic, upholstery, carpeting) out of the
immediate work area.

Do not remove ESD-sensitive components from their anti-static bags until you
are ready to install them.

When handling static-sensitive components, wear a properly grounded wrist
strap (or equivalent).

Avoid unnecessary contact with exposed conductors and component leads with
skin or clothing.
Failure to follow these instructions can result in injury or equipment damage.
