4.6 Installing a Cable Inlet Box for iX4-650H/800H Robots
Grounding the iX4-650HS/800HS Robot Base
Because of the need to seal the junction between the robot base and the frame, the protective
earth ground connection for the iX4-650HS/800HS robots has been moved from the base
mounting pad to inside the iCS-ECAT cable inlet box, which is electrically connected to the
robot base.
The ground screw is marked inside the cable inlet box with a label. Refer to Cable Inlet Box,
showing Ground Label on page 97.
NOTE: The resistance of the earth ground conductor must be ≤ 10 Ω.
Grounding Robot-Mounted Equipment
If hazardous voltages are present at any user-supplied robot-mounted equipment or tooling,
you must install a ground connection for that equipment or tooling. Hazardous voltages can
be considered anything in excess of 30 VAC (42.4 VAC peak) or 60 VDC.
If there will be hazardous voltages present at the tool flange or end-effector, you must:

NOTE: A ground strap from the end-effector to the base mounting pad must
include a service loop that allows full rotation and movement of the tool flange.

Connect the robot cable inlet box to protective earth ground.
l
Ground the end-effector to the robot cable inlet box ground screw.

NOTE: A ground strap from the end-effector to the robot cable inlet box ground
must include a service loop that allows full rotation and movement of the tool
flange.
4.6 Installing a Cable Inlet Box for iX4-650H/800H Robots
Use the following procedure to install an optional cable inlet box to increase the IP rating of
the robot to IP65.
Consider the extra height required to accommodate this unit.

WARNING: ELECTROCUTION RISK Failing to ground robot-mounted equip-
ment or tooling that uses hazardous voltages could lead to injury or fatality of
a person touching the end-effector when an electrical fault condition exists.
