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.
The symbol in the figure is the installation method symbol specified by JEM. Description in parentheses
(
) indicates the earlier JEM symbol.
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.
