Safety
IMPORTANT
Please read this information BEFORE installing the equipment.
Hazards to Personnel
WARNING!
This equipment can endanger life through rotating machinery and high voltages. Failure
to observe the following will constitute an ELECTRICAL SHOCK HAZARD.
Metal parts may reach a temperature of 70 degrees Centrigrade in operation.
Before working on the equipment, ensure isolation of the mains supply from terminals
L1, L2 and L3. The equipment contains high value capacitors which discharge slowly after
removal of the mains supply. Wait for at least 5 minutes for the dc link terminals (DC+ and
DC-) to discharge to safe voltage levels (<50V). Measure the DC+ and DC- terminal
voltage with a meter to confirm that the voltage is less than 50V.
Do not apply external voltage sources (mains suppy or otherwise) to any of the braking
terminals (DC+, DBR).
Application Risk
The specifications, processes and circuitry described herein are for guidance only
and may need to be adapted to the user's specific application.
Parker Hannifin Manufacturing Limited does not guarantee the suitability of the
equipment described in the Manual for individual applications.
This manual is for anyone
installing and operating this
unit.
You must be technically
competent to install and
operate this unit.
Before working on the unit,
isolate the mains supply
from terminals L1, L2 and L3
and wait 3 minutes.
Disconnect the unit from
circuits when doing high
voltage resistance checks.
The unit must be
permanently earthed due
to the high earth leakage
current.
The drive motor must be
connected to an appropriate
safety earth.
Electrostatic discharge
sensitive parts : observe
static control precautions.
