WARNING
This document provides important instructions for a safe installation, operation and
use of the ASYS.
It is advised that this User Manual be consulted before installation of the equipment,
which operation should only be performed by skilled personnel.
DEVICE OVERVIEW
The ASYS is available in two voltage levels, 120 Vac and 220/230/240 Vac.
The nominal current 16A is available for both voltage levels.

The warranty conditions are stipulated in the sales contract. If not the following
points shall apply:
SOCOMEC’s guarantee is strictly limited to the product(s) and does apply neither to
the equipment in which they could be integrated nor to the performance of such
equipment.
The manufacturer, at his discretion, is entitled to adapt his product in order to comply with the warranty or replace the faulty parts. The manufacturer’s warranty does
not apply in the following cases:
- Defects arising either from designs or parts imposed or supplied by the Purchaser,
- Failure due to fortuitous circumstances or force majeure,
- Replacements or repairs resulting from normal wear of units and machinery,
- Repair, modication, regulation or replacement of parts made by a third party or
personnel not qualied without SOCOMEC’s written consent.
The period of validity of the warranty may never exceed 12 months after delivery.
Replacements, repairs or modications of parts during the warranty period cannot
extend the duration of the warranty.
For these stipulations to be valid, the Purchaser must, within a maximum of 8 days
after the warranty lapses, expressly inform the Manufacturer of the faulty design,
or the material or manufacturing defect, stating in detail the grounds for his complaint.
Defective parts replaced free of charge by the Manufacturer are to be put at his disposal, so that he may become the sole owner.
The warranty legally ceases if the Purchaser has, of his own initiative, undertaken
modications or repairs on the Manufacturer’s products without the written consent
of the latter.
The Manufacturer’s liability is limited to the obligations as dened herein (repair or
replacement), all other items of damage being formally excluded.
The Purchaser is liable for taxes or duties of any kind in compliance with either the
European regulations, or those of the country of import or transit.

The 2-pole ASYS is a two-way, single phase automatic switch powered by two independent synchronous or asynchronous AC power supply sources.
ASYS provides redundant power, it makes a rapid switch from one source to the other in the event of a fault to the power supply used to power the load.
One of the two sources can be designated as the preferred power supply, to which
the ASYS will supply the load. It remains there until dierent designations or faults
require it to be switched to the alternate source.
The ASYS is tted with a block diagram with LED indicators, capable of providing all
information concerning equipment operation status, together with the power source
priority selection which enables trained operators to make full use of the apparatus.

2. If the preferred source is out of range, ASYS will automatic transfer to the other
source until the preferred source is recovered within preset tolerance.
3. If both sources are out of range, the ASYS output will be stopped. (Load is not

External protection devices need to be installed upstream and downstream of the
equipment to protect the cables and the unit. Upstream these devices need to be
selected and congured with the size of the unit in mind.
Disconnection devices must always be provided
All protection devices (circuit breakers and fuses) installed upstream of the unit need
to be co-ordinated for discrimination with the ASYS input protection (fuses) and the
ASYS overload capability.
If ASYS overload capacities are exceeded, the unit will switch o the
output.
Depending on overload characteristic the ASYS either will trip the
input fuses or drive only internal power relays to the open position.
