Safety and Installation Instructions

Safety

For safety reasons, the power supply modules must be wired via the female connector H11 (according to DIN 41612,

see section "Accessories") in order to meet national and international safety requirements!

If the output circuit of a DC-DC converter is operator-acces-

sible according to the IEC 950 related safety standards, it

shall be an SELV circuit (Safety Extra Low Voltage circuit,

i.e. a circuit, separated from mains by at least basic insula-

tion, that is so designed and protected that under normal

and single fault conditions, the voltage between any two

conductors and between any conductor and earth does not

exceed 60 V DC).

the output circuit. However, it is the sole responsibility of the

installer or user to assure the compliance with the relevant

and applicable safety standards.

Since the M-family DC-DC converters provide double or re-

inforced insulation between input and output, based on an

input voltage of 250 V AC and 400 V DC, only operational

insulation between the AC mains and the input of the DC-

DC converter is needed according to the following table.

In the following section an interpretation is provided of the

IEC 950 safety standard with respect to the safety status of

If the table below is observed, the output of a DC-DC con-

verter is considered to be an SELV circuit up to a nominal

output voltage of 36 V.

the fully assembled modules are individually tested for elec-

tric strength and earth continuity (see "Supplementary

Data"). All electric strength tests are performed as factory

tests.

In class I equipment the connector protective earthing pin is

leading while it is omitted in class II equipment (no protec-

tive earthing is required). Class II equipment provides rein-

forced insulation between input and output circuitry and

also between input and case. There are two class II Y-ca-

pacitors connected in series between input and output cir-

cuitry instead of havingY-capacitors connected to the case.

The UL 1950 recognition limits the maximum ambient op-

erational temperature of the standard modules to T_A

T_{A max}–15 K. Option U allows the operation in applications

where the full operational temperature range according to

the relevant data sheet and UL 1950 recognition is re-

quired.

During the production process, all transformers and each of

Important Advice

Electric strength tests should not be repeated in the field. Improper test methods, for example overshooting or oscillating

test voltages, voltage slopes exceeding 1 kV/µs, internal Y-capacitors not carefully discharged, etc. can cause severe

damage to switching devices and ICs. Melcher AG will not honour any guarantee/warranty claims resulting from high

voltage field tests.
