Mounting the PA-4 Chassis
2
The PA-4 chassis must be installed in a suitable enclosure that provides the environment
(temperature, etc.) specified in
Table 1-1 on page 10
. The enclosure must also provide a
power disconnect with a method for user service personnel to lock the power in the
OFF
position. This is required for safety, including national and international standards, such
as:
• OSHA ‘Lockout/Tagout’ (USA)
• IEC 204-1
• EN 60204-1
2.1
Space Around the Chassis
When the PA-4 chassis is installed, you must allow 50 mm (2 in) at the front of the chassis
and 25 mm (1 in.) at the top of the chassis for proper air cooling.
DANGER:
Failure to provide and use a suitable disconnect
device could cause death or injury to personnel.
CAUTION:
It is important to keep the air filters clean so the
forced air cooling system can work efficiently. See
Section 6.1 on page 47
for details on cleaning the filters.
