HARDWARE INSTALLATION

Installing a Module

WARNING – Disconnect all power to the unit before installing or removing modules.
Installation of the product must comply with National Electrical Code (NEC), NFPA-70 or Canadian Electrical Code (CED) or any local regulation Authority.

To a 4.3-inch Host

It is recommended that a relay module be installed in Module Position 1 only (shown below).RED LION PM-50 Setpoint Output Dual Relay Module FIG
3

  1. To install a module on the tall side of a 4.3-inch host, align the latches of the module with the host case such that the backplane connector shroud on the module cover aligns with the backplane connector opening in the host case.
  2. To install a module on the short side of a 4.3-inch host, rotate the module 180 degrees and align the latches on the host with the module case so that the I/O connector is facing downward.
  3. Insert the host latches into the openings in the module case by slightly deflecting the latches inward.
  4. Press the module into the host case evenly until the latches engage.
  5. Install-Module Locks between each module as shown by fully inserting the legs of the Module Locks into the slots in the case until the button on the Module Lock aligns with the hole provided in the case. Press fit the button into the hole. Repeat this installation between each module in your system to provide the most secure installation.
  6. When you have finished adding modules, the rear cover should be installed in the same manner as the modules.

To a 3.5-inch Host

It is recommended that a relay module be installed directly onto the back of the host (shown below), not on the back of any other module.RED LION PM-50
Setpoint Output Dual Relay Module FIG 4

  1. Align the latches of the module with the host case such that the backplane connector shroud on the module cover aligns with the backplane connector opening in the host case.
  2. Insert the module latches into the openings in the host case by slightly deflecting the latches inward.
  3. Press the module into the host case evenly until the latches engage.
  4. Install-Module Locks between each module as shown by fully inserting the legs of the Module Locks into the slots in the case until the button on the Module Lock aligns with the hole provided in the case. Press fit the button into the hole. Repeat this installation between each module in your system to provide the most secure installation.
  5. When you have finished adding modules, the rear cover should be installed in the same manner as the modules.

Removing a Module

WARNING – Disconnect all power to the unit before installing or removing modules.

To remove a module from the assembly, first remove the module locks using a small screwdriver as shown. Then disengage the latch by deflecting the latch inward or by using a small screw driver, inserting it into the slot in the side of the case, and prying the latch inward to disengage the latch. Once the latches are disengaged, pull on the module and remove it from the assembly.RED LION PM-50 Setpoint Output Dual Relay Module FIG

WIRING

Wiring Connections

All power, input and output (I/O) wiring must be in accordance with Class I, Division 2 wiring methods and in accordance with the authority having jurisdiction. When connecting relay contacts, you must use a Class 2 circuit according to National Electrical Code (NEC), NFPA-70 or Canadian Electrical Code (CEC), Part I, C22.1 or a Limited Power Supply (LPS) according to IEC/EN 60950-1 or Limited-energy circuit according to IEC/EN 61010-1.
Electrical connections are made via cage-clamp terminal blocks located on the back of the meter. Strip and connect the wire according to the terminal block specifications on Page 2.

Please take care to observe the following points:

  • The power supply must be mounted close to the unit, with usually not more than 6 feet (1.8 m) of cable between the supply and the PM-50. Ideally, the shortest length possible should be used.
  • The wire used to connect the PM-50’s power supply should be at least 22-gage wire suitably rated for the temperatures of the environment to which it is being installed. If a longer cable run is used, a heavier gage wire should be used. The routing of the cable should be kept away from large contactors, inverters, and other devices which may generate significant electrical noise.
  • A power supply with an NEC Class 2 or Limited Power Source (LPS) and SELV rating is to be used. This type of power supply provides isolation to accessible circuits from hazardous voltage levels generated by a mains power supply due to single faults. SELV is an acronym for “safety extra-low voltage.” Safety extra-low voltage circuits shall exhibit voltages safe to touch both under normal operating conditions and after a single fault, such as a breakdown of a layer of basic insulation or after the failure of a single component has occurred. A suitable disconnect device shall be provided by the end user.RED LION PM-50 Setpoint Output Dual Relay Module FIG 6
