2 Installation
2.4.2 Installation Standards
• Inside the Control Panel
The conditions inside the control panel should be the same as the environmental con-
ditions of the SERVOPACK. Refer to 2.1.2 SERVOPACK Installation Environment.
The SGDV-B SERVOPACKs have an Installation Environment monitor
(Un022). With this monitor, operation conditions in the installation environment can
be observed and measured.
The value shown on this monitor should be equal to or less than 100% for optimum
operating conditions.
If this value is over 100%, one of the following measures must be taken to ensure
safe operation and a long product life.
Improve air circulation around SERVOPACKs.
Minimum Air Circulation Rate
Top (10 mm): 0.5 m/s
Bottom (10 mm): 0.2 m/s
To improve the air circulation to meet these minimum standards and to lower the per-
centage shown on the monitor, widen the space between the SERVOPACKs or lower
the temperature of the surrounding air.
<Note>
For every increase of 10C, the percentage shown on the monitor will also increase
by approximately ten.
