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.
WARNING
LEAKAGE/GROUNDING CURRENT HAZARD
Leakage/grounding currents are >3.5 mA. Improper grounding of the MSD 510 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
applicable local and national electrical standards and directives, and the instructions in this manual.
WARNING
HIGH VOLTAGE
The MSD 510 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
maintenance may lead to death or serious injury.
-
Installation, commissioning, and maintenance may only be performed by qualified personnel.
WARNING
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.
