4.3 Connection of the AC cabling
This is a Safety Class I product (supplied with a protective grounding terminal).
Uninterruptible protective grounding must be provided at the AC input
and/or output terminals and/or chassis grounding point located externally
on the product.
The MultiPlus is provided with a ground relay (relay H, see appendix B) that
automatically connects the Neutral output to the chassis if no external AC supply is
available. If an external AC supply is provided, the ground relay H will open before the
input safety relay closes. This ensures the correct operation of an earth leakage circuit
breaker that is connected to the output.
- In a fixed installation, uninterruptable grounding can be secured by means of the
grounding wire of the AC input. Otherwise the casing must be grounded.
- In a mobile installation, interrupting the shore connection will simultaneously disconnect
the grounding connection. In that case, the casing must be connected to the chassis (of
the vehicle) or to the hull or grounding plate (of the boat).
- In case of a boat, direct connection to the shore ground is not recommended because of
potential galvanic corrosion. The solution to this is using an isolation transformer.
The mains input & output terminal connector can be found on the bottom of the MultiPlus,
see appendix A. The shore or mains cable must be connected to the connector with a
three-wire cable. Use a three-wire cable with a flexible core and a cross section of 2.5
mm².
Procedure (see appendix A)
Proceed as follows to connect the AC cables:
The AC output cable can be connected directly to the male-connector. (the connector pulls
out!)
The terminal points are indicated clearly. From left to right: 'N' (neutral), earth, and 'L1'
(phase).
The AC input cable can be connected directly to the female-connector. (the connector pulls
out!)
The terminal points are indicated clearly. From left to right: 'L1' (phase), earth, and 'N'
(neutral).
Push the 'input' connector into the AC-in connector.
Push the 'output' connector into the AC-out connector.
