5 Electrical Installation
5.1 Warnings for Electrical Installation
During electrical installation, observe the relevant local and national regulations in addition to the information in this manual.
W A R N I N G
LEAKAGE/GROUNDING CURRENT HAZARD
Leakage/grounding currents are >3.5 mA. Improper grounding of the ISD 510/DSD 510 servo drives and the system modules may
result in death or serious injury.
For reasons of operator safety, use a certified electrical installer to ground the system correctly in accordance with the appli-
cable local and national electrical standards and directives, and the instructions in this manual.
W A R N I N G
HIGH VOLTAGE
The servo system contains components that operate at high voltage when connected to the electrical supply network. There are
no indicators on the components that indicate the presence of mains supply. Incorrect installation, commissioning, or mainte-
nance may lead to death or serious injury.
Installation, commissioning, and maintenance may only be performed by qualified personnel.
W A R N I N G
HIGH VOLTAGE
Potentially lethal voltage is present on the connectors that may lead to death or serious injury.
Before working on the power connectors (disconnecting or connecting the cable), disconnect the PSM 510 from the mains
and wait for the discharge time to elapse.
5.2 Electrical Environmental Conditions
Compliance with the following electrical environmental conditions is necessary to enable safe and effective operation of the servo
system:
Only for use in TN-S, TN-C, TN-CS, TT (not corner earthed) supply earthing system
Prospective short-circuit current: 5 kA
Protective class I
Grounded 3-phase mains network, 400–480 V AC ±10%
3-phase frequency 44–66 Hz
3-phase lines and PE line
External supply for auxiliary voltage, 24–48 V DC (PELV) ±10%
AC choke (see
)
Observe the national statutory provisions.
The leakage current is >3.5 mA.
N O T I C E
RCD COMPATIBILITY
The servo system contains components that can cause a DC current in the protective earthing conductor, which may result in
malfunction in any devices connected to the system.
Where a residual current-operated protective (RCD) or monitoring (RCM) device is used for protection in case of direct or
indirect contact, use a type B RCD or RCM device on the supply side of the system components.
