RGU-100B

Instruction Manual

3�7�- INSTALLATION CONNECTIONS

All active conductors that supply the loads or part of the installation where protection is required must

pass through the associated

WGB

transformers.

Connect the

WGB

transformer to the

RGU-100B

using the RJ45 cable,

WGB

RGU-100B

RJ45

Channel 1

Figure 12: RGU-100B - WGB connection�

Note:

If a RJ45 connection cable other than the one supplied with the

WGB

is used, it must have a

cross-section of 4 x 2 x AWG24/7. The cable must be a maximum length of 9 metres.

Connect the output relay of the

RGU-100B�

If the installation is modified and it involves new transformer, a replacement of the

WGB

, the

RGU-

100B

will detect this change and light the screens in yellow, see

"5�2�- PROBLEMS OR CHANGES IN THE

INSTALLATION"�
