4-2 Power Supply TRM95 Installation and Connection
Safety Please adhere to the following safety precautions:
1. Only authorized personnel are qualified to install and repair the Power Supply
unit.
Caution To reduce the risk of an electrical shock, disconnect the AC main supply before
removing the unit’s cover.
2. Use only approved (CSA,UL, IEC) fuses, size 5x20mm, Type T” (slow-blow), with
appropriate rating (1A for 120Vac, or 0.5A for 230Vac). The correct fuse rating is
marked on the front panel of the Power Supply unit.
3. Ensure that the Power Supply unit is properly grounded. Always connect the unit
to the 3-wire (with grounding) power systems.
4. Ensure that no water does not get inside the unit. Ensure that no foreign objects
get inside the unit.
Wiring Connections and Supply
To get inside the unit, you must first unscrew the two screws that secure the cover.
Once you remove these screws, you can easily lift the cover.
Note To completely detach the cover, you must also remove the cover’s ground connection.
Remember the ground connections must be in place when the unit is operating
normally.
All unused knockout-punch holes (front and back panels) must be plugged with plugs
or similar stoppers. Lyngsoe recommends using the Hole Plug PG11 (P/N 400617)
with a Polyamid Nut (P/N 400645). You have to order these parts separately.
You must secure all cables passing through the front or back panel with cable grips or
connectors (these are not provided). The connectors must match the conduit type used
to protect the cable outside the Power Supply unit. For more information on these
parts, contact Lyngsoe Industries.
For all interconnections (power line, equipment), Lyngsoe recommends using cable
type SJT, PVC jacketed, 3-conductors with a minimum gauge of 16 AWG (0.75 mm
2
-
conductor nominal cross-sectional area). Lyngsoe recommends BELDEN cable type
19353.
An external disconnecting device will be provided as part of the building’s installation.
The disconnecting device will have an appropriate rating for the AC power line
voltage (minimum 1A for 120Vac or 0.5A for 230Vac). Installation of the external
wiring will comply with the national wiring rules (code) applicable to the site.
