Equip any disconnectable connections with connectors and couplings
with grounded metal housing.
●
For unshielded cables of an electric circuit, twist the supply and return
conductors.
Electrical wiring
Hot surface!
The surface temperatures at the self-con‐
tained servo-hydraulic linear axis may be
high. Electrical cables which were installed in
close proximity to the axis can be overloaded,
thus heating up inadmissibly, and in the worst
case suffer an insulation fault.
WARNING
●
Install cables at a sufficient distance to hot surfaces or prevent over‐
heating by proper installation of the cables.
Improper connection of electrical compo‐
nents!
If electrical components are connected or
wired improperly, short-circuits or severe
damage to persons and property may result.
CAUTION
●
Connect the electric components according to the wiring diagram.
●
Wiring and connection work may only be carried out by Bosch Rexroth
or by authorized and qualified personnel of a specialized company that
was authorized by Bosch Rexroth, see
chapter 2.4 "Qualification of per‐
●
Observe the safety instructions in this chapter and in
uct-specific safety instructions" on page 11
●
Before starting to install the cabling of the self-contained servo-hydraulic
linear axis, the following work must have been completed:
–
Mechanical installation of the self-contained servo-hydraulic linear
axis.
–
The control cabinet is fixedly installed at its place of installation or
use. Please observe
chapter 7.3 "Installation conditions" on page
. The position or distance of the individual components (self-con‐
tained servo-hydraulic linear axis, control cabinet) is significantly
influenced by the length of the cable set.
Wire the individual components (self-contained servo-hydraulic linear axis,
drive controller) of the scope of delivery according to the electric circuit dia‐
gram, see also required and supplementary documentation.
Connecting the synchronous unit -
M1 to the self-contained servo-hy‐
draulic linear axis
To connect the plug-in connectors with threaded port, please proceed as fol‐
lows:
1.
Place the power connector in the correct position at the thread of the
connector housing.
