• Restricted extension of the cable network:
Generally speaking, the use of cable extensions or distributors on the instagrid ONE max
is possible without any problems. However, considering the two points outlined below,
opting for an overall expansion of the cable network that is as low as possible is advisable:
• In order to ensure rapid tripping (<100 ms) of the electronic fuse of the outlet
[section 3.2] in the event of a short circuit, the wire resistance between the
instagrid ONE max and loads must not exceed a value of 1.5 Ω. A wire with a
cross-section of 1.5 mm² achieves this resistance at a length of approx. 60 metres
(including live and neutral conductors; excluding contact resistances at plug
connections).
• When the overall length of the cable network increases, its clarity is reduced. The
probability of discovering a cable damaged in operation which could result in an
earthing at the outlet of the instagrid ONE max reduces correspondingly.
• Regular electrical checks of the loads used:
If an electrical device is used mainly in an IT (isolé-terre) network, the probability of
discovering insulation faults is reduced. For this reason, regular checks of the loads used
(as required by DGUV V3 [German Accident Prevention Regulation 3]) by an electrical
specialist are imperative.
3.4 Passive protection at the inlet
The charging inlet [8] is protected from overload by a fuse, which can be replaced by the user;
see [section 7.1] .
4. INITIAL COMMISSIONING
Before putting the device to use for the first time, carry out the following steps:
• Check the package for external damage.
• Open the package at the top.
• Take out the instagrid ONE max by the handle together with the side cushion.
