Installation

Fig. 1.5

– Wiring Block

For convenience there are two ground terminals: one inside the cover and one external, located close
to the conduit entries.

Use of twisted pair (22 AWG or greater than) cables is recommended.

Avoid routing signal wiring close to power cables or switching equipment.

The unused outlet connection should be plugged and sealed accordingly.

The

LD301

is protected against reverse polarity.

The Figure 1.6 - Conduit Installation Diagram, shows the correct installation of the conduit, in order to
avoid penetration of water, or other substance, which may cause malfunctioning of the equipment.
