Inspection and Preparations
Motor Mounting
A. Upon delivery of the gearbox, conrm that you
received the exact model that was specied on your
purchase order.
B. Inspect for shipping damage. Notify the shipping
agent immediately if any damage is discovered.
C. Remove the protective covering from the
output shaft.
D. Clean and de-grease the motor mounting surface
and shaft, as well as the gearbox mounting surface,
input hub bore, and shaft bushing (if included). This
cleaning is very important for the shaft and bushing,
to prevent slip during motion.
A. Remove the access hole plug, allowing access to the
motor shaft clamp.
B. Carefully align the shaft bushing (if included)
so that the opening in the bushing aligns with
the opening in the input hub. It is also recom-
mended that the motor shaft keyway (if present)
aligns with the opening in the input hub clamp.

Input Hub
C. Rotate the gearbox input hub so that the clamp
bolt is aligned with the access hole. Loosen the
clamp bolt.
D. Remove the motor key (if supplied), as it is not
required for proper installation and operation.
E. Slowly slide the motor into the gearbox, so that
the motor shaft enters the gearbox input hub
with motor shaft keyway (if present) aligned with
gearbox input shaft clamp opening. Install the four
motor ange bolts in a cross-wise pattern, to ensure
proper alignment of motor to gearbox. Tighten the
bolts to the proper torque using a torque wrench
(see Table A).

Safety Precautions
IP 65 Versions
If you have received an IP65 version of the gearbox, be
sure to seal between the gearbox and motor interface
with a sealant to ensure an IP65 rating of the gearbox /
motor assembly. Also apply sealant to the access hole
plug during step “G”. Please contact NIDEC-SHMPO with
any questions.
Table A
Tighten the gearbox input shaft clamp bolt to the
proper torque using a torque wrench (see Table B).
F.
G.
Table B
Re-install the access hole plug into the motor adapter
plate. Assembly is complete.
A. Avoid use in wet or corrosive areas, unless the gear-
box is specied for these environments.
B. Ambient temperature in the area of the gearbox
must be in the range of 0° -40°C, unless the gearbox
is built to withstand a dierent temperature range.
C. The gearbox (with motor) must be rmly attached
to a vibration-free frame or xture.
D. The gearbox has been lubricated and can be operat-
ed immediately.
E. At initial operation, check the direction of shaft
rotation, then apply the load gradually.
F. Avoid excessive loads.
G. Ensure that the motor speed does not exceed the
maximum RPM specied for the gearbox.
H. Watch for the following problems and discontinue
motion immediately:
I. The gearbox is not designed to be disassembled.
J. The gearbox is lubricated for its lifetime with appro-
priate grease. No re-lubrication is required.
a. Sharp increase in temperature
b. Abnormal noise
c. Unstable output speed
