2 For your own safety
2.5
Personal protective equipment
Always use personal protective equipment during the transport, installation, start-up,
cleaning, maintenance and removal of the servo drive, for example:
l
Protective gloves
To prevent superficial hand injuries.
l
ESD safety shoes
To prevent foot injuries caused by falling parts.
To prevent electrostatic charging.
l
Protective work clothes
To prevent superficial injuries and soiling.
l
Protective goggles
To prevent eye injuries caused by dust or shards/splinters.
l
Light respiratory protection
To prevent the inhalation of harmful substances.

Safety notes for installation and
maintenance
Dangerous electrical voltage!
Prior to performing any maintenance tasks, you need to ensure that the power supply
and the external power supply of the servo drive have been disconnected and secured
against reconnection and that the DC bus has discharged.
During operation and also for a very long time after the servocontroller has been
switched off, the corresponding connections and an external braking resistor carry
dangerous DC bus voltages. Contact with these voltages may result in serious or even
fatal injuries.
Make sure that the DC bus has discharged by measuring at the DC bus terminals ZK+
and ZK- or wait for the maximum discharge time. This is for BL 4100-M / BL 4100-D
30 minutes
. For BL 4800-M / BL 4800-D no waiting time is required. In the event of a
device defect, connections other than those specified here may also carry a life-
threatening voltage. Under these circumstances, the discharge time must be waited for
in any case.
Risk of burns due to hot surfaces
The servo drive and, in particular, the (external or internal) braking resistor may become
hot during operation. Always wait a sufficient amount of time prior to touching these
parts.
Always use suitable personal protective equipment to avoid severe burns.
Risk of injury for unqualified personnel!
Only personnel who are trained and qualified for working on or with electrical devices are
authorised to install, maintain and repair the servo drive.
