Wiring Overview - Kollmorgen SILVERLINE S/O Series Manual

4.5.2 Mounting S/O Units on an SPS/R
SPS/Rs include mounting holes for up to four S/O units. The number of S/O units that can be mounted is specified
when you order your units. See the SPS/R outline drawing in Section 3 for more information.
4.5.3 Mounting S/O Units without an SPS/R
S/O units must be mounted vertically. These units are convection cooled and require 6mm (0.25") clearance on both
sides, as well as at least 25mm (1") above and below. See the S/O outline drawing in Section 3 for more information.

4.6 WIRING OVERVIEW

The customer is responsible for providing proper circuit breaker or fuse protection. The customer is responsible for
providing proper wire gauge and insulation rating for all wiring, including motor, AC line, and DC bus. The
customer is responsible for making sure that all system wiring and electrical protection comply with all applicable
national and local electric codes.
When wiring your S/O system, observe the following guidelines:
•
Twist all AC leads to minimize electromagnetic emissions (noise).
•
Avoid running signal leads in close proximity to power leads, motor stator leads, or other sources of
electromagnetic noise. Run signal leads in separate conduit from power leads. Shields are recommended for
signal leads.
•
Minimize lead lengths.
•
Provide adequate strain relief for all cables and wires.
4.7 WIRING GROUND AND BUS
4.7.1 Wiring the Ground with an SPS/R
To prevent shock hazard and to ensure proper operation of the system, the bus- and the motor must be grounded. The
S/O is not isolated from bus-; therefore, grounding bus- will ground the S/O.
GROUND bus- and motor
PROPERLY! Failure to provide
proper grounding can result
in a shock hazard.
WARNING
4.7.2 Providing the DC Bus
The S/O is configured at the factory for operation from a 40-volt DC (max) bus. Regulated supplies may provide up
to 40 volts, providing that regulation is within 2% over all line and load conditions.
The maximum allowed nominal bus voltage varies with the power supply line/load variation. Better regulation allows
higher nominal bus voltage. However, the nominal value must be selected so that in no case will the bus voltage
exceed 40 VDC.
