YRM2.DIODE Installation Manual

Product Description

The YRM2.DIODE is a redundancy module for building redundant power supply systems. It is
equipped with two input channels and one output. The two inputs are decoupled by diodes.
The device has a monitoring circuit included. Two LEDs and two relay contacts signal when one of the
two DC-input voltages is not in range due to a non-functioning or disconnected power supply.

Intended Use

This device is designed for installation in an enclosure and is intended for commercial use, such as in
industrial control, process control, monitoring and measurement equipment or the like. Do not use this
device in equipment where malfunction may cause severe personal injury or threaten human life.
The redundancy module can be used with any type of power supply as long as the maximum output
current ratings are not exceeded. It is suitable for power supplies with continuous overload current as
well as any kind of intermittent (Hiccup) overload behavior.

Installation Instructions

Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Do not ground or earth the positive output pole which could prevent redundancy in case of a ground
failure. Ground the negative output pole, when needed.
Use only power supplies with a negligible output ripple voltage in the low frequency range between
50Hz and 10kHz when used in marine applications according to the GL regulations.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the top of the

Other mounting orientations require a reduction in output current.

device.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper
cables that are designed for a minimum operating temperature of 60°C for ambient temperatures up to
+45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temperatures up to +70°C.
Ensure that all strands of a stranded wire enter the terminal connection.
Unused screw terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments.

No condensation or

frost is allowed.
The enclosure of the device provides a degree of protection of IP20.
The input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order to
maintain a SELV or PELV output.
Check correct input polarity. The device will not operate when input voltage is reversed.
The device is designed as “Class of Protection III” equipment according to IEC 61140.
A PE (ground) connection is not required. However, connecting the chassis ground terminal to ground
can be beneficial to gain a high EMI immunity.
The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid!
The device is designed for altitudes up to 6000m (19685ft). See additional requirements in the product
datasheet for use above 2000m (6560ft).
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and
right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. When the device
is permanently loaded with less than 50%, the 5mm can be reduced to zero.
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the
same as the ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.

Installation Instructions for Hazardous Location Areas

The device is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group II
Category 3 (Zone 2) environments.
Hazardous Location classification: ATEX: EPS 11 ATEX 1 312 X, II 3G EX ec nC IIC T4 Gc

WARNING EXPLOSION HAZARDS!

Substitution of components may impair suitability for this environment.
Do not disconnect the device unless power has been switched off or the area is known to be non­hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP54
and fulfils the requirements of the EN 60079-0.

Functional Description

The device can supply any kind of loads, including unlimited capacitive and inductive loads.
Do not apply return volt a g e s from t h e l o a d t o t h e o u t p u t h igher t h a n 2 0 0 V d c .
Both input voltages are monitored individually. The green Input-OK LEDs report an input voltage
above 21.5V for the corresponding input channel.
The Input-OK relays monitor the input voltages. The contact is closed, when the Input-OK LED is on.
Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
