Connecting and Assembling the CCA630 Connector
1 Open the two side shields for access to the connection terminals. The shields can
be removed to make wiring easier. If removed, replace them after wiring.
2 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
six 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 ).
6 Tighten the two CCA630 connector fastening screws on the rear panel of
Sepam™.

Connecting and Assembling the CCA634 Connector
1 Open the two side shields for access to the connection terminals. The shields can
be removed, if necessary, to make wiring easier. If removed, replaced them 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 (1A) or 8 (5A) 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
six 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 retaining tabs into the slots on the base unit.
7 Pivot the connector toward 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.

CAUTION
HAZARD OF IMPROPER OPERATION
Do not use a CCA634 on connector B1 and
residual current input Ir on connector E
(terminals 14 and 15) simultaneously.
b Though unconnected to a sensor, a
CCA634 on connector B1 will disturb input
Ir on connector E.
Do not use a CCA634 on connector B2 and
residual current input I'r on connector E
(terminals 17 and 18) simultaneously.
b Though unconnected to a sensor, a
CCA634 on connector B2 will disturb input
I'0 on connector E.
Failure to follow this instruction can cause
equipment damage.
