Installation, Wiring and Maintenance
 
Install the Servo Drive, Servomotor, and peripheral equipment before wiring. 
Not doing so may cause electric shock.
Be sure to ground the 100-VAC or 200-VAC input model Servo Drive and Servomotor to 
100 Ω or less, and the 400-VAC input model to 10 Ω or less.
Not doing so may cause electric shock.
Do not remove the front cover, terminal covers, cables, or peripheral equipment while the 
power is supplied.
Doing so may cause electric shock.
Before carrying out wiring or inspection, turn OFF the main circuit power and wait for at 
least the following specific time.
Not doing so may cause electric shock or burning.
10 minutes: R88D-1SN06F-ECT, R88D-1SN10F-ECT, R88D-1SN15F-ECT, 
R88D-1SN20F-ECT, R88D-1SN30F-ECT, R88D-1SN55F-ECT, 
R88D-1SN75F-ECT, R88D-1SN150F-ECT
15 minutes: R88D-1SN01L-ECT, R88D-1SN02L-ECT, R88D-1SN01H-ECT, 
R88D-1SN02H-ECT, R88D-1SN04H-ECT
20 minutes: R88D-1SN04L-ECT, R88D-1SN08H-ECT, R88D-1SN10H-ECT, 
R88D-1SN15H-ECT, R88D-1SN20H-ECT, R88D-1SN30H-ECT, 
R88D-1SN55H-ECT, R88D-1SN75H-ECT, R88D-1SN150H-ECT
Do not damage, pull, or put excessive stress or heavy objects on the cables.
Doing so may cause electric shock, malfunction, or burning.
Use appropriate tools to wire terminals and connectors. Check that there is no short-circuit 
before use.
Not doing so may cause electric shock.
Connect the frame ground wire in the motor cable securely to the  or FG of the Servo 
Drive.
Not doing so may cause electric shock.
Provide safety measures, such as a fuse, to protect against short circuiting of external wir-
ing and failure of the Servo Drive. Not doing so may cause a fire.
Install the Servomotor, Servo Drive, and peripheral equipment on non-flammable materials 
such as metals. Not doing so may cause a fire.
Keep conductive or flammable foreign objects such as screws, metal pieces, and oil out of 
the Servo Drive and connectors. Pay particular attention to the connector on the top part of 
Servo Drive. Not doing so may cause a fire or electric shock.
Design the configuration to cut off the main circuit power supply when the ERR signal (nor-
mally close contact) of the control output function is output (open).
Not doing so may cause a fire.
Do not bundle the motor cables.
Not doing so may cause fire.
