SPECIFIC WARNINGS
To guarantee the IP protection during the installation, expect to seal the instrument cables
(with silicone or foam) after having tightened the cable-gland.
Through the installation expect suitable protections to avoid product overheating (eg. a
shelter to avoid direct sunlight); similarly for low temperatures. Do not open in case of bad
weather conditions (rain, snow, etc). Expect the recurring substitution of the hygroscopic
salts.
Do not install in small locations and/or without ventilation, with high humidity, in potentially
dangerous areas or where is prescribed the use of explosion proof components.
Electrical connections on the product must be executed only from qualified and expert per
-
sonnel, in compliance with actual rules and regulations.
For external network powering, the plug at the end of the cord has ground contact; the
grounding of the powering is provided from the plug inserted in the socket. The product
powering source must be divided from dangerous voltage parts with double insulation and
must guarantee an insulation of at least 3000 Vrms.
Be sure to have, in the plant, a suitable protection from electric short circuit (for example
high sensitivity differential circuit-breaker at the root of the AC/DC power supply unit).
Before any maintenance on the product, the powering must be disconnected.
Avoid any action that can short-circuit the rechargeable battery poles.
To enable the product protections, expect a connection to the ground plant through a proper
green-yellow grounding connector; this connector must be connected to the proper ground
clamp (or to any bolt if it is a metal cabinet).
Verify periodically rechargeable battery voltage; expect a substitution after roughly 5 years
and if the voltage measured on the poles is too low (eg. 10.5V for a battery with nominal
voltage 12V) and investigate on the causes.
Using the product differently from the one expected from the manufacturer can compromise
safety conditions.
The use of parts other than original spare parts could lead to irregular functioning or even
dangerous situations for person and things.
