•
Output range: 24 V DC ±10%
•
Maximum current: 1 A
Use a 24 V supply unit that is CE marked for industrial use. Ensure that the supply fulfills the PELV specification and is only used for the
system safety input.
A common supply for auxiliary and safety supply can be used, provided the only connection point of the 2 circuits is near to the supply.
This is intended to avoid interference due to a common voltage drop. The maximum cable length between the 24 V supply unit and
the servo system is 3 m.
The safety supply can be looped from PSM 510 to the other MSD 510 system components except for ACM 510, which does not have an
STO connection. The cable for this is not provided. For further information, see
.
NOTICE
-
Ensure reinforced isolation between safety signals and other signals, supplies (mains supply), and exposed conductive
parts.
5.7 UL Requirements
NOTICE
-
Integral solid-state short-circuit protection does not provide branch circuit protection. Branch circuit protection must be
provided in accordance with the National Electrical Code/Canadian Electrical Code, and any additional local codes or
equivalent.
-
Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical amperes, 480 V maximum when
protected by maximum 80 A class J or T fuses.
-
To meet the UL (Underwriters Laboratories) regulations, use a UL-approved copper cable with a minimum heat-resistance
of 60 °C. Use Class 1 wire only. For PSM 510 rated 30 kW, use a maximum heat resistance of 75 °C.
-
Control Circuit Overcurrent Protection is required.
