CHAPTER 1 INSTALLATION
1.1.3 Installing the Servomotor
The servomotor can be installed horizontally or vertically with the shaft facing up or down. The same
rule applies to the brake-incorporated servomotor and gear head.

1.1.4 Water Proof and Oil Proof Properties
The servomotor itself has resistance against splashes in relatively
small amount. However, the shaft-through part is not water proof
or oil proof. Take mechanical protective measures to block entry
of water and oil.
Install a cover in environments susceptible to much water, oil or
oil mist.※Keep the temperature inside the cover to 40-degree or
less.
Do not operate with cables immersed in oil.
Some coolant types can provide on sealant, cable, case or
similar.
To install the servomotor horizontally, install so that the
servomotor cables face down.
To install the servomotor vertically or at an oblique direction, route
the cables to secure a cable trap (see the figure on the right).
In case of a servomotor equipped with an oil seal, although noise
might be created from the oil seal, it will not effect any functional
operation.
To install the servomotor equipped with an oil seal in an orientation
with the shaft facing up, take measures to avoid accumulation of oil
at the oil seal lip.
※The protection level is the initial property.
