1. General Safety Instructions
• This manual provides instructions on safety, connections and operation of the HIC4xxA Automatic
Transfer Switching Equipment.
• Whether the HIC4xxA is sold as a loose product, as a spare, as an enclosed solution or as any other
configuration, this device must always be installed and commissioned by qualified and experienced
personnel, in line with the manufacturers recommendations, following good engineering practices and
after having read and understood the details in the latest release of the relative product instruction
manual.
• Maintenance on the product and any other associated equipment including but not limited to servicing
operations must be performed by adequately trained and qualified personnel.
• Each product is shipped with a label or other form of marking including rating and other important
specific product information. One must also refer to and respect markings on the product prior to
installation and commissioning for values and limits specific to that product.
• Using the product outside the intended scope, outside Hager recommendations or outside the
specified ratings and limits can cause personal injury and/or damage to equipment.
• This instruction manual must be made accessible so as to be easily available to anyone who may
need to read it in relation with the HIC4xxA.
• The HIC4xxA meets the European Directives governing this type of product and includes CE marking
on each product.
• No covers other than that for auto/manu on the HIC4xxA should be opened (with or without voltage)
as there may still be dangerous voltages inside the product such as those from external circuits.
• Do not handle any control or power cables connected to the HIC4xxA when voltage may be present
on the product directly through the mains or indirectly through external circuits.
• Voltages associated with this product may cause injury, electric shock, burns or death. Prior to carry
out any maintenance or other work on live parts or other parts in the vicinity of exposed live parts,
ensure that the switch including all control and associated circuits are de-energized.
• As a minimum the HIC4xxA comply with the following international standards:
- IEC 60947-6-1
- GB 14048-11
- EN 60947-6-1

2. Introduction
HIC4xxA “Automatic Transfer Switching Equipment” (ATSE) is designed for use in power systems for
the safe transfer of a load supply between a normal and an alternate source. The changeover is done in
open transition and with minimum supply interruption during transfer ensuring full compliance with IEC
60947-6-1, GB 14048-11 and other international TSE standards as listed.
The HIC4xxA is a full load break (switch type) derived transfer switching equipment where the main
components are proven technology devices also fulfilling requirements in IEC 60947-3 standards.
As a Class PC ATSE, the HIC4xxA is capable of “making and withstanding short circuit currents”
assigned to IEC 60947-3 utilization categories of up to AC23A, GB 14048-11, IEC 60947-6-1 and
equivalent standards with utilization categories of up to AC33B.
HIC4xxA transfer switches ensure:
• Power Control and Safety between a normal and an alternate source.
• A complete product delivered as a fully assembled and tested solution.
• Intuitive HMI for emergency / local operation.
• Integrated and robust switch disconnection.
• Window with clearly visible position indication I – 0 - II.
• An inherent failsafe mechanical interlock.
• Stable positions (I – 0 – II) non affected by typical vibration and shocks.
• Constant pressure on the contacts non affected by network voltage.
• Energy Efficient with virtually no consumption whilst on the normal, alternate or off positions.
• Extremely rugged, error free and built in padlocking facility (configurable).
• Straight forward installation with effective ergonomics.
• Simple motorization control interface.
• ATS configuration through 4 potentiometers and DIP switches.
• Auxiliary contacts for switch positions I – 0 - II (optional).
• “Product availability” output.
• Ample accessories to suit specific requirements.
• Fully integrated ATS controller specifically designed for Mains / Mains and Mains / Genset
applications.

9.3.3. Three phase without neutral network
For three-phase networks without neutral (3NBL) 400 VAC, a neutral must be recreated to allow the
HIC4xxA to operate at 230 VAC. To recreate the neutral, we recommend the use of quantity 2x 400 VA
auto-transformers connected as shown below. The neutral position must be defined as neutral on the
left or neutral on the right in advance and then wired accordingly. The example below shows the wiring
for a product configured with neutral on the left.
A new product must have the neutral configuration pre-programmed as on the left or on the right at the first
start up using a real (not a recreated) 3 phase + neutral supply.

9.3.5. Procedure for the configuration and storage of the neutral position
230/400 VAC network configurations without neutral conductors.
SI SII
Step 1
It is first necessary to connect the HIC4xxA in three-phase + neutral
(4NBL) to allow configuration of the neutral position (neutral position
is detected at the first power-up).
Step 2
Connect the autotransformers.
Neutral must be connected as shown in the drawing above in
section "9.3.4. Auto-transformer connections", see previous
page.

9.3.6. Reset of neutral position
In case the network is not recognized by the HIC4xxA (or in case you would like to change the neutral
position), proceed as follows:
Step 1
Ensure that the product is powered and within voltage limits.
Open the AUTO/MANU cover.
Step 2
Set DIP Switch 1 from 3P to 1P.
Step 3
Set DIP Switch 1 from 1P to 3P.
Step 4
Close the cover.
End of the procedure for detecting the neutral position.
