CAUTION
HAZARD OF IMPROPER OPERATION
Do not use a CCA634 and residual current input
I0 on connector A (terminals 18 and 19).
Even if it is not connected to a sensor, a CCA634
will disturb input I0 on connector A
Failure to follow this instruction can cause
equipment damage.
.
Connecting and assembling the CCA630 connector
1. Open the 2 side shields for access to the connection terminals. The shields can
be removed, if necessary, to make wiring easier. If removed, they must be replaced
after wiring.
2. If necessary, remove the bridging strap linking terminals 1, 2 and 3. This strap is
supplied with the CCA630.
3. Connect the wires using 4 mm (0.16 in) ring lugs and check the tightness of the
6 screws that guarantee the continuity of the CT secondary circuits.
The connector accommodates wires with cross-sections of 1.5 to 6 mm²
(AWG 16-10).
4. Close the side shields.
5. Plug the connector into the 9-pin inlet on the rear panel (item B
).
6. Tighten the 2 CCA630 connector fastening screws on the rear panel of Sepam.
Connecting and assembling the CCA634 connector
1. Open the 2 side shields for access to the connection terminals. The shields can
be removed, if necessary, to make wiring easier. If removed, they must be replaced
after wiring.
2. According to the wiring required, remove or reverse the bridging strap. This is used
to link either terminals 1, 2 and 3, or terminals 1, 2, 3 and 9 (see picture opposite).
3. Use terminal 7 (1 A) or 8 (5 A) to measure the residual current according to the
CT secondary.
4. Connect the wires using 4 mm (0.16 in) ring lugs and check the tightness of the
6 screws that guarantee the continuity of the CT secondary circuits.
The connector accommodates wires with cross-sections of 1.5 to 6 mm²
(AWG 16-10).
The wires only exit from the base.
5. Close the side shields.
6. Insert the connector pins into the slots on the base unit.
7. Flatten the connector against the unit to plug it into the 9-pin SUB-D connector
(principle similar to that of the MES module).
8. Tighten the mounting screw.
