Victron energy EasySolar 12/1600/70 Manuel D'instructions page 13

Procedure
Proceed as follows to connect the battery cables:
Use an insulated box spanner in order to avoid shorting the battery.
Avoid shorting the battery cables.
Connect the battery cables: the + (red) and the - (black), to the battery see appendix A.
Reverse polarity connection (+ to – and – to +) will cause damage to the product. (Safety
fuse inside the EasySolar chassis can be damaged)
Secure the nuts tightly in order to reduce the contact resistance as much as possible.
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 EasySolar 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, an 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 (for example, with a shore current plug), 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
Compact, 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 2.5mm².
Procedure
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 (left-side).
Push the 'output' connectors into the AC-out connector (AC0 to AC3 from left to right-side).
