Mains connections

DANGER: Risk of electric shock from live
parts
Even when the master switch is off, the
input terminals of the master switch L1, L2
and L3 and are live. Contact with the input
terminals of the master switch L1, L2 and L3
will lead to electric shocks, heart failure and
fatal injury.
¶
Work in the control cabinet is only to be
performed by qualified electricians or au-
thorized personnel under the supervision
of a qualified electrician.
¶
Cover or cordon off live parts.
!
The EPS 610 must be connected to the mains
(400 V - 440 V). It is recommended to use a current-
limiting circuit-breaker with a rating of 300 mA.
!
The minimum cross-section of the incoming mains
cable is 6 mm .
2
1. Connect a three-phase mains cable of capacity 40 A
from a three-phase mains isolator of 40 A with fuse /
MCB as a protective device.
2. Route the mains cable through the protective gland
located at the bottom of the control cabinet to the
main switch.
3. Connect the mains supply to the main switch termi-
nals as follows:
$
L1 to terminal 1 on main switch.
$
L2 to terminal 3 on main switch.
$
L3 to terminal 5 on main switch.
$
Neutral to terminal 7
$
Power earth to system power earth (earthing link)
at the bottom of the control cabinet.
i
Ensure that the system ground is connected to the
power earth terminal of the incoming 3-phase supply
via a 10 mm green / yellow earth cable.
2
!
Ensure that the conduit, which connects to the main
supply bus bars is properly grounded.
4. Conduct a Megger test to check if the earthing is OK.
5. Check the primary voltage of the control trans-
former. The primary terminal connections should be
modified as per the measured primary voltage.
i
Observe the label pasted on the test oil motor to
find the correct direction of rotation. If the direction
of rotation is incorrect, switch off the master switch
and the mains supply. Interchange any two phases at
the mains and ensure that the motor runs in correct
direction.

7. Rotate the HMI such that the HMI stud
(Fig. 14, Pos. 2) is directly above the slot on the
front panel (Fig. 14, Pos. 5).
8. Insert the spring washer (Fig. 14, Pos. 3) and the
dome nut (Fig. 14, Pos. 4) into the lever.
9. Insert the lever through the slot in the front panel
