Installation/Fitting
5.6.5 Connecting the Power Supply Cable
1.
Assemble the power supply cable according to
the connector pin assignment in 4.4.2.3 24 V DC
Power Supply (X4).
2.
Connect the power supply cable from the power
supply module to connector X1.
3.
Secure the power supply cable using the strain
relief clamps on the underside of the connection
box.
5.6.6 Connecting the Safety Cable
The safety cable connects external safety relays to the
connection box. Therefore the STO safety function can be
realised via an external safety relay.
1.
Assemble the safety cable according to the
connector pin assignment in 4.4.1.1 Safety Switch
Connectors (Safety I & Safety II).
2.
Connect the safety cable to connector Safety I or
Safety II.
Use connector Safety I for line 1 and Safety II for
line 2.
3.
Connect the safety cable shield to PE.
5.6.7 Connecting the Brake Cable
The brake cable connects the brake chopper to an external
brake resistor.
1.
Assemble the brake cable according to the
connector pin assignment in 4.4.2.2 Brake
Connector (X5).
2.

ISD Connection Box Operating Instructions
5.6.8 Connecting/Disconnecting Hybrid
The hybrid (feed) cable connects the connection box to
the first servomotor in the servo system, either directly or
via a slip ring for turntable applications. All other
servomotors are connected via a loop cable.
HIGH VOLTAGE
Potentially lethal voltage is present on the connectors.
Before working on the power connectors (disconnecting or
connecting the cable), disconnect the power supply
module from the mains and wait for the discharge time to
elapse.
DISCHARGE TIME
The servomotors, the connection box and the power
supply module contain DC link capacitors, that remain
charged for some time after the mains supply is switched
off at the power supply module.
To avoid electrical shock, fully disconnect the power
supply module from the mains before carrying out any
maintenance on the ISD servo system or its components.
Wait for at least the time listed below before carrying out
maintenance work:
Number
0-60 servomotors
Note: High voltage may still be present even if the LED on the
