Observe the Installation instructions in Σ -V series User’s Manual Setup
Rotational Motor (SIEPS80000043) or Σ -V series User’s Manual Setup Lin-
ear Motor (SIEPS80000044).
For installation sites, use proper care with the following notes.
Situation Notes on Installation
When installed in a control
panel
• Design the control panel size, unit layout, and cool-
ing method so that the surrounding air temperature
of the SERVOPACK does not exceed 55 ° C.
• When installing multiple SERVOPACKs side by
side in a control panel, install cooling fans and pro-
vide sufficient space around each SERVOPACK to
allow cooling by fan and natural convection.
When installed near a heat-
ing unit
Suppress radiation heat from the heating unit and a
temperature rise caused by convection so that the sur-
rounding air temperature of the SERVOPACK does
not exceed 55 ° C.
When installed near a
source of vibration
Install a vibration isolator underneath the SERVO-
PACK to prevent it from receiving vibration.
When installed in a place re-
ceiving corrosive gases
Corrosive gases do not immediately affect the SER-
VOPACK but will eventually cause SERVOPACK or
contactor-related devices to malfunction. Take appro-
priate action to protect against corrosive gases.
Others • Avoid installation in a hot and humid place or where
excessive dust or iron powder is present in the air.
• Be sure there is no condensation or freezing.
• Keep the surrounding air temperature 45 ° C or less
to ensure long-term reliability.
