Safety and Installation Instructions
Pin Allocation
The pins of PSC models are printed onto the case of the
regulator.
The pin allocation of PSL models is shown in the table below:

Positive Switching Regulators
Standards and Approvals
All switching regulators are class-I equipment and have been
approved according to UL 60950, CSA 60950, and IEC/EN
60950-1 2 nd Ed.
The regulators have been evaluated for:

surveillance in accordance with the above mentioned
standards and with ISO 9001:2000.
Isolation
The resistance of the protective earth connection (max. 0.1 ? ) is
tested only for PSL models.
PSC models: Electric strength test voltage between input
connected with output against case: 2200 VDC, ≥ 1 s (for some
PSC models only with version V103 or higher).
PSL models: The electric strength between the input, intercon-
nected with the output, and the case is tested with 500 VDC (all
-2 models), 750 VDC (models with V i max = 80 V), or 1500 VDC
(models with V i max = 144) during ≥ 1 s.
1
R-input is used for the inhibit function. Consequently, option R
and i exclude each other.
These tests are performed in the factory as routine test in
accordance with EN 50116 and IEC/EN 60950. The electric
strength test should not be repeated by the customer.
Installation Instruction
Installation must strictly follow the national safety regulations
in compliance with the enclosure, mounting, creepage,
clearance, casualty, markings, and segregation requirements
of the end-use application.
Check for hazardous voltages before connecting.
Connections of PSC models can be made using fast-on or
soldering technique. PSL models should be plugged into a
DIN-rack
The input and the output circuit are not separated, i.e., the
negative path is internally interconnected.
The regulators should be connected to a secondary circuit.
Do not open the regulator !
Ensure that a unit failure (e.g., by an internal short-circuit)
does not result in a hazardous condition.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids must be prevented, since the power supplies
are not hermetically sealed.
Protection Degree
The protection degree is IP 30 (IP 20, if equipped with option
P, D, or D1). It applies only, if the regulator is plugged-in or the
matching female connector is properly attached.
Railway Application
The regulators have been developed observing the railway
standards EN 50155 and EN 50121. All boards are coated with
a protective lacquer.
