Fan unit installation procedure
Insert the positioning part of the fan unit vertically, align it to the positioning part of the main unit case, and tighten with screws.
Use the same screws as those used for the fan unit before replacement.
2.5 Restrictions when using this product at an altitude
exceeding 1000 m and up to 2000 m
Altitude and ambient temperature
As heat dissipation effects decrease in proportion to the decrease in air density (5 °C per 1000 m), use the product within the
ambient temperature range shown in the following figure.
When mounting servo amplifiers close together while using them in environments comparable to those within the diagonal
lines in the figure above, use them at an effective load ratio of 75 % or less.
Input voltage
Generally, withstand voltage decreases as altitude increases; however, there is no restriction on the withstand voltage. Use in
the same manner as when the altitude is 1000 m or less.
Parts with a service life
■Smoothing capacitor
The capacitor will reach the end of its service life in 10 years of continuous operation in an air-conditioned environment (with
an ambient temperature of 30 °C or less).
■Relays
There is no restriction. Use in the same manner as when the altitude is 1000 m or less.
■Servo amplifier cooling fan
There is no restriction. Use in the same manner as when the altitude is 1000 m or less.
