CAUTION – Risk of electric shock. Capacitors store hazardous energy. Do not remove cover until 5 minutes after
disconnecting all sources of supply.
CAUTION – Risk of electric shock. This Inverter / UPS receives power from more than one source. Disconnection of the AC
source and DC source is required to de-energize this unit before servicing.
CAUTION - For continued protection against risk of fire, replace only with same type and rating of fuse.
Insulated tools must be used at all times when working with live systems.
When handling the system/units pay attention to sharp edges.
3.3 Installation
The iIverter System contains output over current protection in the form of circuit breakers. In addition to these circuit
breakers, the user must observe the recommended UL listed upstream and downstream circuit breaker requirements as
defined in this manual.
UL listed (DIVQ) branch overcurrent protections have to be provided by others / by customer.
Please use extreme caution when accessing circuits that may be at hazardous voltages or energy levels.
The modular inverter rack is a dual input power supply. The complete system shall be wired in a way that both input and
output leads can be made power free.
When AC Mains is not connected, the output AC circuit is considered as a separately-derived source. If local codes require
grounding of this circuit, use the identified terminal for bonding this circuit to the enclosure. Ground the enclosure to a
suitable grounding electrode in accordance with local code requirements.
Ground the enclosure to the electrode terminal.
Remove output neutral-to-ground jumper when input AC MAINS is connected.
Use 90°C copper wires / conductors only.
AC and DC circuits shall be terminated with no voltage / power applied.
The safety standard IEC/EN62040-1-1 requires that, in the event of an output short circuit, the inverter must disconnect in
5 seconds maximum. The parameter can be adjusted on T2S; however, if the parameter is set at a value >5 seconds, an
external protection must be provided so that the short circuit protection operates within 5 seconds. Default setting is 60
seconds.
The system is designed for installation within an IP20 or IP21 environment. When installed in a dusty or humid
environment, appropriate measures (air filtering …) must be taken.
3.3.1 Handling
The cabinet shall not be lifted using lifting eyes.
Remove weight from the cabinet by unplugging the inverters. Mark inverters clearly with shelf and position for correct
rebuild. This is especially important in dual or three phase configurations.
Empty inverter positions must not be left open. Replace with module or cover.
