D5C
Grounding
In order to maintain the operational reliability of the D5C, be sure to
ground the blue or black wire of the power cord.
The service power supply of the PC (Programmable Controller) is not
available to the D5C-1D
@
0. The negative line of the service power
supply of the PC is not grounded. Therefore, the D5C may not oper-
ate.
Furthermore, if the negative line of the service power supply is
grounded, the noise resistance of the PC will drop.
Provided that single-phase 200 V is supplied to the D5C-1A
@
0, if
one phase is grounded, the power supply will be short-circuited and
a machinery breakdown will result. Use an isolating transformer and
ground the secondary side of the transformer instead.
In the above case, be sure to ground the secondary side, otherwise
the D5C may not operate.
Mounting
Do not tighten the nuts with excessive force. The maximum permissi-
ble tightening force of each nut with a washer is 29.4 N • m.
Others
Do not disassemble the D5C, otherwise the internal wiring will be
damaged and the D5C will fail to operate.
The sealing of the D5C uses nitrile butadien rubber (NBR), which is
highly oil resistive. If exposed to some types of oil or chemical
indoors or outdoors, however, the NBR may deteriorate. Contact your
OMRON representative for details.
When mounting the antenna to the D5C, be sure to tighten the
antenna to a torque of 0.39 to 0.83 N·m. If the antenna is not tight-
ened securely, the built-in contact may break.
If an appropriate antenna is mounted to a free attachment model,
hold the nut on the outer side with a wrench so that the nut will not
move. Then tighten the nut on the inner side within a torque range of
0.78 and 1.18 N·m.
