The PROTECT 1. may only be operated with or connected to a three-phase power system with protective grounding using a mains connection cable with PE conductor that has been tested according to German standards (VDE).

Risk of burning!

The battery has powerful short-circuit currents. Incorrect connection or isolation faults can lead to melting of the plug connections, sparking potential and severe burns!

The unit has a warning signal that sounds when the battery voltage of PROTECT 1. is exhausted or when the UPS is not working in its normal mode (see also chapter 6.1 "Signalling”, page 47ff and the following).

Observe the following safety instructions to ensure permanent operational safety of and safe work with the UPS and the battery modules (special accessories):

♦Do not dismantle the UPS!

(The UPS does not contain any parts that require regular maintenance. Bear in mind that the warranty will be invalidated if the unit is opened!)

♦Do not install the unit in direct sunshine or in close proximity of heaters!

♦The unit is designed to be installed inside in heated rooms. Never install the housing in the vicinity of water or in an excessively damp environment!

♦Condensation may occur if the UPS is brought from a cold environment into the room where it is to be installed. The UPS must be absolutely dry prior to start-up. As a result, leave it to acclimate for at least two hours.

♦Never connect the mains input and the UPS output!

♦Ensure that no fluids or foreign bodies can penetrate the housing!

♦Do not block the air vents of the unit! Make sure, for example, that children do not insert any objects in the ventilation openings!
